Choosing a College Chemistry Course Can Be Difficult
Choosing a College Chemistry Course Can Be DifficultIf you are one of the thousands of people who have taken a course at Temple University, then you will be familiar with the many exciting ways that you can study at this great institution. If you do a little bit of research you will be able to find out that the many courses that they offer can be taken at any time, however for those who have special needs, special offers or an allergy to some of the materials, then it is best to consider studying at an alternative college.Many people are unsure what to expect when they visit this university and want to know whether this is a good place to go to school. When considering the teaching style, the first thing that you need to do is talk to the professors to find out what they feel is important. These are people who are well qualified to teach you, so if you are looking for an educational experience that is special, then it would be best to take a look at the curriculum that they offer.As a large group of students at the university, you are sure to be able to find a number of professors who are passionate about teaching chemistry. The students that they have are often some of the brightest in the country and they are taught by some of the best teachers in the country. This gives them the chance to work with a variety of different people and learn something new each day.When deciding which college chemistry course is best for you, you are likely to come across a number of different choices. One of the most common choices that you will find will be a chemistry course from a college or university that is accredited by the National Institute for Standards and Technology (NIST).NIST is a really good choice for those that need to take basic courses in this area as this is one of the best places to get all of the materials that you need. The NIST course will also give you the opportunity to take your coursework home and study there so that you will be able to study at any t ime of the day or night.For those that need to take more advanced chemistry courses, you will probably want to choose one of the many courses offered at a college that is an accredited by the American Chemical Society (ACS). ACS offers a lot of great options for taking courses at this level, and this is a good choice for those that want to learn more about organic chemistry.This area of chemistry is important to those that have chosen this study program because it can help them in their future work in the medical field. Whether you are looking to get into a career as a science teacher or a chemist working in labs, then it is essential that you consider a college course that is accredited by one of these bodies.

Reaction Occurrences Every Day
Reaction Occurrences Every DayOne of the most difficult things for a chemist to understand is the chemical reactions that occur in everyday life. In fact, many of us are better at it than chemistry professors because we live in these processes every day. This means that it can be difficult to remember, let alone see, how reactions really work and why they happen in the way that they do.A simple example of a reaction is when one substance reacts with another. Let's look at some of these reactions that occur every day:Carbon dioxide is gas. When you get this gas out of the automobile, for example, it has changed from the solid state into the gaseous state. But just as a reaction happens between the materials in an automobile, so too do chemical reactions happen between gases and solids. Now, a metal like zinc or copper react with oxygen in air by forming a compound called chromium or nickel. This is called a metal-oxidizer reaction.When you add iron to tin, the tin becomes tin oxide. T hen tin oxidizes (changes into a brown metallic state) to tin. And just as a metal oxidizes in air, so too does the tin when added to other substances.If a tiny amount of iron is present in water, it will become iron sulfate. If the iron is very small and doesn't start to change or react immediately with anything else, it is a carbonate-alkali-acid compound.The absorption of carbon dioxide by nitric acid causes a chemical reaction. This reaction causes an alkaline metal to become a form of sodium metal, which has to be separated from the acid before it dissolves. The result is NaOH, which separates the nitric acid from the alkaline metal. There is a certain degree of stoichiometry involved here: a higher pH means a higher affinity for the acid, and sodium ions have a higher affinity for a higher pH.There are many more reactions that occur every day in your home. Some of them are quite common and also very easy to remember, while others are slightly less common but still useful. Let' s review the most common reactions, starting with some of the most important ones and moving on to more complex reactions.
