Purpose How do we determine the reaction type and write a balanced equation for chemical reactions? Background Discussion There are many kinds of chemical reactions and several ways of classifying them. One popular and useful method is to classify reactions into five major types. These are: (1) synthesis, (2) decomposition, (3) single replacement, (4) double replacement, and (5) combustion. Most reactions can be put into one of these categories. In a synthesis reaction, two or more substances

DESIGN Aspect 1: Problem: The problem is will there be a chemical reaction taken place that is able to be observed. Variables: Manipulated: The different chemicals we use for each reaction. Responding: The observation of the chemical properties to see if a new chemical has been formed while the reaction is taking place. Controlled: The surface area of the calcium solid, the volume of chemicals, and the intensity of the flame from the Bunsen burner. Aspect 2:

Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (the electrode: a metal or a semiconductor) and an ionic conductor (the electrolyte). These reactions involve electron transfer between the electrode and the electrolyte or species in solution. If a chemical reaction is driven by an externally applied voltage, as in electrolysis, or if a voltage is created by a chemical reaction as in a battery, it is an electrochemical

for balancing equations practice and discussed using the lowest coefficient possible as well as following proper convention for symbols. We moved on to reviewing an example for writing word equations as well as percent composition. During the percent composition you ensured we understand each step must be included for full point in case of an error during our procedure. We finished the eChat reviewing empirical formulas as well molecular formulas and discussing stoichiometry and the chemical recipe

a low of 2.27. Introduction A buffer solution is a solution that is made up of water and a chemical which gives it unique properties with regard to its pH. The chemical is referred to as buffer agent. The buffer agent resists changes in pH when exposed to bases and acids. The aforementioned property makes it useful in dealing with various chemical accidents, protecting sensitive equipment and balancing internal processes of a number of living things. A buffer agent dissolved in water makes a buffer

STUDENT STUDY GUIDE FOR 8TH GRADE CHEMISTRY Welcome to chemistry. Chemistry is the science of matter and its interactions. Everything around you is made of atoms – atoms and their chemical combinations, molecules. Everything you can see, touch, smell, and taste is made up of chemicals. So, the science of chemistry is a very wide ranging science. Parts can concentrate on how interactions of atoms and molecules allow the nerves in your body to conduct electrical signals. Other parts might concentrate
