Using the Percent Difference Formula Chemistry

Using the Percent Difference Formula ChemistryA percent difference formula is a chemistry equation used in most different types of spectroscopy. This is a very useful type of equation for any person to have because it can be very helpful in any investigation that you would like to conduct. This is because the formula can be very helpful in determining how the light behaves when it hits the instrument.Using the percent difference formula, it is possible to determine what components of the spectrum that are responsible for the color of the instrument. The scientific method, that this science is based on is quite simple and easy to understand. In most cases, it is used in chemistry labs to determine what compounds are present in the spectra and how they will react.The first part of the formula determines the absorption of light and then the second part of the formula determines how much light is absorbed. Once the percent difference has been calculated, then it is important to know that this is what the spectra will look like when it is viewed through the spectroscope. Once this information is gathered from the laboratory, then the next step is to study the spectra to determine if there are substances that are present in the spectra that can cause a chemical reaction when they come into contact with the instrument.Some of the substances that will react with the instrument will absorb more light than others will. When this is figured out, then it is important to know if there are certain substances that will react with the instrument in a certain way or not. This can help to determine if there are impurities that should be checked for before they are allowed to be released into the atmosphere.The percent difference is a very useful tool for many different scientific investigations. There are many different experiments that can be conducted through this type of method. It is important to be careful with how this type of information is handled in order to keep a safe work environment for everyone involved.It is important to note that the percentage of absorption is always the same, however, it is always recommended to use a different percentage of absorption when testing other gases. The percentage of absorption is different depending on whether the gas is solid or liquid. There are also different formulas when it comes to gas solubility which are needed for different tests.Once you are able to determine what the different levels of absorption are and what the percent difference is, then it is time to add up all of the numbers. Once the numbers are added up, then it is important to know how the amounts will change depending on the composition of the gel. This will help to determine if the proportions are correct or not.One of the biggest problems with using the percent difference equation is that you will have to take different numbers and determine if they are correct based on the way the gel is made. There are many different chemicals that wi ll cause the percentages to change and this will need to be taken into consideration when applying the equation. It is important to know that this is a good thing, but only if you take the time to understand how the equation works and how it can be used properly.

Teacher QA Exploring Abu Dhabi public schools with Lindsey, part 2

Teacher QA Exploring Abu Dhabi public schools with Lindsey, part 2 Abu Dhabi public schools offer incredible opportunities, great salaries, and extensive benefit packages for teachers. This post contains the second half of my interview with Lindsey, who taught in Abu Dhabi public schools for five years. Make sure you check out part 1 here first. What were some of the largest differences between Abu Dhabi public schools and North American ones? Did they pose challenges for you personally? Lindsey: There are many differences and similarities. Kids are kids no matter where they grow up. However, the school climate can be very different. A personal challenge of mine was getting over my Western-centric attitude. Most Westerners suffer from this without even realizing it. What I mean is that I had to remind myself constantly that there is no right way, or superior way, or better way. There are different ways to do things and one is no more right than the other. Once I accepted this concept, school life became a lot easier for me. Other things I found challenging was the language barrier - not so much between my students and I, but between myself and the staff. I am a social person by nature, so it was difficult when I would try to communicate with staff, especially because I was one of two female teachers in my entire school when I first arrived. To help solve this problem, I asked some of the Arabic teachers to teach me Arabic basics in return for English basics from me. This was a great way for us to find common ground and build a relationship. Another major difference I found was the lack of recess for students. Students get an average of 20 minutes of total break per day due to the fact that the school day is packed into only five hours. What are the resources and support systems like for educators in Abu Dhabi public schools? Lindsey:The Abu Dhabi public schools are going through an incredible reform, which means that year by year, sources and support systems are improving. There are plans that have been designed by ADEC to support students and educators. Also, I felt support by other teachers and the administration at my school. I find that most Emiratis see value in the education reform and are therefore are very open minded. How did you positively handle problematic classroom behaviour from students? Did you need new strategies? Lindsey:I watched a lot of teachers struggle, including myself, with student behaviour. As a fairly junior level teacher, it was a lot to take on a class of 28 grade 2 boys that had not only never had an English-speaking teacher, but that also had never had a female teacher either. I think reflecting back on the experience, this helped me grow as an educator. I was able to use trial and sometimes a lot of errors to try different techniques. In the end, the most successful method was reinforcing positive behaviour. I implemented a class tracking system and only rewarded students for good deeds done. The students started to intrinsically motivate themselves to make good choices. With the UAE’s education reform in place, what subjects are taught in English? Did you teach any of these? Lindsey:English Language Arts, Math, and Science are all taught in English. I taught all three subjects. What level of English could the students speak? Lindsey:There was a wide spectrum of English speaking ability. Some students were fluent English speakers, readers, and writers. Other students could speak English but could not read or write. Other students had no concept of the English language. Teachers have to be comfortable with different skill levels and understand how to meet the needs of the students in their classroom based both on ability and learning style. How was your experience with communicating with parents? Lindsey:Some parents were very approachable, easy to speak with, gracious, and supportive. Otherparents were more challenging to speak with because of their limited English ability and my limited Arabic language ability. In these situations, I would rely on my Arabic partner teacher for translation. Overall, I had a very pleasant experience with the parents of the students I taught. Did you meet other new teachers when you arrived? Were there onboarding or orientation events and activities for new staff? Lindsey:I met so many new friends when I arrived! Everyone is in the same situation as you are and therefore very open and friendly. I found teachers that had already been living there extremely helpful and willing to offer assistance to help me settle in. There was a week long orientation that I participated in. Representatives from the schools went through major processes and curriculum. They briefed us on living in the UAE, dos and don’ts, and helped familiarize us with where to go and what for. They also helped us set up a bank account and a cell phone. They were very helpful and patient. During orientation, which took place in Abu Dhabi City, we were placed in hotels. When I started, there wasn’t a Head of Faculty position, however, when I was a Head of Faculty one of my duties was to welcome new teachers to the school and help them get adjusted to the school climate as well as answer any questions they may have. How did you get along with other teachers at your school? Lindsey:I love getting to know all different types of people. I worked in a coed staff, which is rare in Abu Dhabi. The advantage was that I had colleagues from all over the world and I could learn from their teaching methods to expand my own professional growth. The teachers were very kind, welcoming, and inviting. What is the number one reason a teacher should experience teaching abroad? What is the number one reason a teacher should experience teaching in Abu Dhabi public schools? Lindsey:The number one reason a teacher should experience teaching abroad is for the overall professional and personal growth experience. Teachers should experience teaching in the Abu Dhabi public schools because it is an amazing opportunity to be on the forefront of a unique and ambitious education reform. Most teachers at home never see the big picture. Their students pass by year after year and it’s hard to feel that “I’m making a difference” satisfaction. In Abu Dhabi it’s totally opposite. Teachers can experience the difference they are making first hand! They are helping to re-shape the educational climate in the country, on the front lines and can see the incredible growth and of their students. It is very professionally satisfying work. What would you say to other teachers considering teaching abroad? Lindsey:Just do it! It’s a scary thing to consider, but the pros FAR outweigh the cons. I fell head over heels in love with living abroad! Everyone should have this experience of a lifetime! I can see myself going abroad again if the right opportunity presents itself.

3 books all parents should read

3 books all parents should read As a parent I am always looking for answers to a whole lot of questions. Parenting is no easy feat and as parents we are always open to advice and tips from other parents who have already been there. Children are precious. They are individuals with their own characters and their own minds. There are some books that offer great insight into children that we may not have thought of or not be aware of. And some books are so inspirational and full of great ideas on how to become better parents that they shouldn't be missed. Here are three books I think all parents will find inspiration from: 1. HOW to TALK so KIDS will LISTEN and LISTEN so KIDS will TALK - Adele Faber Elaine Mazlish This is one of my favourites. This best-selling book gives you great insight into how to effectively talk to your children so that you can build solid, trusting relationships. It is a very down-to-earth book with fabulous suggestions of practical ways to solve those everyday problems we parents face with our children. The book offers valuable lessons in breaking argument patterns, coping with negative feelings, engaging your child's cooperation, resolving conflicts and a whole lot more. It is basically a guide to enriching your relationship with your children. An absolute must-read for new parents or parents with young children. 2. The Magic Years: Understanding and Handling the Problems of Early Childhood - Selma H. Fraiberg The great thing about this book is that it takes the reader into the mind of the young child and takes the reader through the way the young boy looks at the world and how he handles situations. This classic book offers a diverse look into how children think and the reasons they behave the way they do; delving into their actions based on their emotions and cognitive abilities. Understanding why our children act in certain ways and seeing the world through their eyes can really help in understanding our children better and build a better relationship with them. 3. No Regrets Parenting: Turning Long Days and Short Years into Cherished Moments with Your Kids - Harley Robart, M.D. Most parents can probably agree that time flies by when our children are young. This book explores how busy parents don't notice how quickly time flies by and how to spend the time they do manage within the day enhancing their relationships with their children through quality time. The book delves into how to enjoy the experience of parenting whilst juggling with the rest of your daily routines from work, housework, homework and cooking to football practice, ballet and bath time. It concentrates not on how much time you spend with your children but how you spend that time with them helping parents re-adjust their priorities.

Chemistry - Reaction Mechanism

Chemistry - Reaction MechanismReaction mechanism is the means to control the chemical properties of a material. The chemical property of a substance can be changed through chemical reaction, which is highly productive in the development of science. Reaction mechanism will modify chemical compounds and transform the original chemical substances into new materials. By increasing the productivity of chemical compounds, chemists are able to discover new elements and compounds.Reaction mechanism in organic chemistry includes the method in which matter is broken down, and the steps of the process. Most chemical reactions take place by heating the raw materials. Sometimes, the raw materials are cold in order to achieve higher temperature and to develop reactions faster. In reaction mechanism, the properties of the elements are changed at different temperatures. There are two different mechanisms which include percolation and crystallization.Percolation is the method in which heat is used to destroy the crystal structure. In the process, heat is applied to create gaps between molecules, which in turn makes the chemical bonds dissociate. This creates space for the molecule to move towards its equilibrium position in the neighboring molecule.Crystallization is the method in which the molecular weight is altered. To alter molecular weight, an organic compound is mixed with a metal and other chemicals. In this process, a new crystal structure is formed.In reaction mechanism, chemical elements are changed on the molecular level. Chemical elements are changed from one state to another by use of a different mechanism. The first mechanism is that of heating, which produces energy to run a reaction. It requires no input of chemical power by the user.In reaction mechanism, there are different reactions used in organic chemistry. With the use of different mechanisms, chemical compounds are altered into different products. Besides, various chemical compounds can be formed from the reactants.Other than reaction mechanism, there are other processes used in organic chemistry. A reaction involves the breaking down of carbon chains to produce carbon dioxide, water, and other gases. The formation of different carbon units may also take place in the reaction mechanism. At times, the reaction is self-sustaining and is not dependent on any external input.

While the present day affords us with any information we desire at the click of a button, it can still be a difficult task to follow the history of South American food.The main reason for this can be found in the various political and social events that have marked the continent, for better and for worse. In terms of food, however, everything from creole, or criollo, culture to the slave trade presented South American countries with lasting recipes. From the Spaniards and indigenous peoples, to the Andes Mountains and the Amazon basin â€" this guide follows how the dynamic and diverse evolution of food in South America.Maize, or corn, has been a staple in the southern hemisphere for centuries GiovanniC ooking Teacher 4.83 (12) £25/h1st lesson free!Discover all our tutors HalimaCooking Teacher £12/h1st lesson free!Discover all our tutors HakimCooking Teacher 5.00 (5) £50/h1st lesson free!Discover all our tutors VincenzoCooking Teacher £30/h1st lesson free!Discover all our tutors GinellaCooking Teacher £30/h1st lesson free!Discover all our tutors ArronCooking Teacher 5.00 (2) £9/h1st lesson free!Discover all our tutors JoshuaCooking Teacher 5.00 (5) £30/h1st lesson free!Discover all our tutors FlickCooking Teacher 5.00 (1) £50/h1st lesson free!Discover all our tutorsWhat Exactly is South American Cuisine?In order to be able to truly savor the deliciously diverse gastronomy of South American countries, we’ll have to start by looking at the history of the continent. While we may think of the continent of South America as a static concept today, its rich history is enough to toss monolithic notions of the “pre-Columbian” Americas away.One of the theories  on how the first “Americans” arrived involves the Ice Age and a very long land bridge that connected Asia and North America, known as the Bering Bridge. While this dates their first arrival before 10,000 BC, there are actually many Native Americans that have their own origin or creation stories.The earliest evidence of agriculture in South America, including staples such as potatoes, chilies and beans, has been traced to 6500 BC. Ecuadorian ceramic has suggested the earliest settlements were found there. Other early civilizations included Colombian Chibchas and Bolivian Aymara to Peru where the Quechuas settled.Whether you’re interested in Venezuelan or Argentinian food, much of South America’s eating habits stem from the diets of early civilizations in the region. Some examples of the foods integral to this diet include lima beans, the black bean, quinoa, corn, chocolate, and cassava.The origins of many of the famous South American dishes we recognize today have a much more complicate d background, each plate telling a story of joy, conquest, exploitation and creativity. In fact, many of the classics that can be found in South American restaurants and households have their roots in immigrant populations.Lookup for the best cooking classes London on Superprof.One great example of this can be found in a fruit we have grown to love around the world: the banana. While you may be familiar with the small, yellow banana found in most food markets â€" it’s cousin, the plantain, is actually green and typically much bigger.The plantain is native to regions in Southeast Asia and Oceania, whose countries introduced the delectable fruit to traders in Madagascar. While it quickly became a stable ingredient in West and Central African countries, the slave trade that began with Spanish invaders is actually what spread the plantain across the Atlantic. The plantains, stored as provisions for slaves, made their way into the households and diets of the Americas.From the Andean mo untains to the Argentine and Chilean Tierra del Fuego, much of South American cuisine as we recognize it today has been influenced by immigration and colonization, from the language that is spoken in a given country to the diet that sustains them.In Brazil, for example, large swaths of the indigenous population were killed by the diseases brought by Portuguese invaders looking to use the communicates as labour for their sugar cane plantations. This led to the mass enslavement and forced migration of West Africans, who introduced ingredients like coconut milk, peppers and palm oil.In countries like Bolivia and Peru, however, some ancient agricultural practices have remained staple dishes throughout the course of history. Quinoa, considered sacred by the Incan Empire, domesticated the plant and, because of its high nutritional value, have kept using it in their dishes.While borders have been and will always be contested, people generally name thirteen countries under the umbrella term of South America:ArgentinaBoliviaBrazilChileColombiaEcuadorIslas Malvinas (Falkland Islands)French GuianaGuyanaParaguayPeruSurinameUruguayVenezuelaSome countries of South America are home to the Magellanic penguinWhether you’re looking at the Uruguayan or Guyanese diet, every South American country has been influenced by both European colonization, the slave trade and immigration. In Guyana, for example, the Dutch and British colonizers brought many indentured workers from various countries, a fact that is echoed in Guyanese cuisine. Where Indian workers popularized curry and roti dishes, the British left a lasting tradition of bread-making.People who were considered to be creole, who were born in the European colonies throughout Latin America, also brought about many innovations in the sphere of food, especially in Brazil and Peru.In Argentina, the dishes that typify national cuisine in the country either stem from their ancient civilizations or the various European forces that were active in the region. Where the French and Italians brought about pastries and pastas, the Spanish are said to have introduced the now famous empanada. Famous plates with indigenous origins include locro, a stew with Andean roots, humitas and yerba mate.Immigration has played an equally as important role in forming the diets of South American countries. From street food to comfort food, the largest migrant groups to have left a lasting imprint on the continent have come from Japan, the Philippines, China, and Africa.Start to learn with the best cooking courses around.In fact, because of the rapid changes brought about by the forces of colonization and migration, much of the population in South America is incredibly diverse. While in Brazil, the majority of the population have European ancestry, countries like Bolivia contain the highest percentage of those with indigenous ancestry. Whether you’re visiting Machu Picchu or the various salt flats in Argentina and Bolivia, there will be a varied and delicious assortment of culinary treats to try.Latin American Recipes Originating from South America?While most American countries have been influenced by South American cuisine, trading in a hot dog or macaroni in favor of plantain and hominy, the flavors of the continent have actually spread worldwide. Before delving into how these flavors have been adapted on the global scale, it’s helpful to start by looking at the many variations of the same dishes within Latin America.Eaten either as street food and comfort food, arepas are an excellent example of how one dish can be adapted to the unique tastes of each country. An arepa is, at its core, a fried and savory, cornmeal based dough ball. Stuffed with black bean or avocado in Venezuela, arepas in Colombia are typically mixed with ham and cheese. Looking towards Central American countries, the pupusa is a traditional dish made in El Salvador that is comparable to arepas. Stuffed with cheese, beans or vegetable s, it is equally as popular in Honduras.While ingredients like raisins, lima beans, cassava, beans and rice have become staples to South American diets throughout the years,   these are also ingredients that can be found used in many kitchens around the world. In fact, besides the fish stew or clam chowder found in French Guiana, a dish called fricassee can be found replicated around the world. This meat stew, made with game meat and served with rice, can be found in the Caribbean as well as in France.Peruvian ceviche is another great example of how similarities in food can bring people closer. While the origins of this dish are contested, it is generally prepared as a fresh, seafood salad. While in Mexico this dish is served on top of tostadas, a crisp-like tortilla, the dish can also be found in the Asian Pacific. Kinilaw, native to the Philippines and dating back to around the 10th century, is prepared using raw fish, vinegar, chili and herbs.All countries in South America enjoy some of the best coffee in the worldSouth American Cuisine to Try At HomeFrom chimichurri sauce and churrasco to empanadas and tamales, food culture in South America offers everyone a chance to find something easy and affordable to make. Whereas some dishes, like the Rio de Janeiro specialty feijoada, can be found on the global scale, there are some recipes that unique to South American countries.Focusing on dessert, one recipe that is sure to satisfy your taste buds is the Paraguayan kaguyjy. Also known as mazamorra, the Paraguayan version calls for corn, honey, milk and sugar boiled into a hearty, sweet soup.While many countries of the Americas have desserts that require flour, such as apple pie or churros, many countries offer dishes that don’t need flour at all. Besides kaguyjy, the Surinamese bojo cake is another example of this. Made with rum soaked raisins, coconut milk, cassava, and coconut oil â€" this cake exemplifies the best of South American desserts.If you’re looki ng for a drink that moves past your standard caipirinha, make sure to check out some recipes for pisco or chicha. While pisco is a liquor typical of Chile and Peru, chicha is a corn drink that can be found throughout South America either fermented or not. Regardless of what you pick, any recipe from the continent will be sure to satiate your cravings.
