Become a master in STOICHIOMETRY!!!

Chemistry Preparatory

Dear students,

Goal: In this activity you will perform calculations for keeping and maintaining the law of concervation of matter and energy.

According to the studied contents, here you are going to find basic concepts, statements and exercises for aquiring a better understanding by solving two activities. Read them and prepare your materials for performing calculations about ratios in chemical reactions.

Stoichiometry

Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements. In order to use stoichiometry to run calculations about chemical reactions, it is important to first understand the relationships that exist between products and reactants and why they exist, which require understanding how to balanced reactions.

Topics you will need to revise before getting started with this activity:

-   Balancing equations 
-   Molar ratios
-   Limiting reagent

Activity 1.

Activity 2

Solve the following exercises: (Important! for this activity you will have to solve only the last link Practice Final Exam, Multiple Choice Only
.

Ever sit at home and wonder if you were doomed to fail the upcoming quiz?  Well, now you can find out for sure by doing a bunch of practice problems.  Actually, my real purpose for putting these practice worksheets on the internet is that I want you to learn the material --  as the saying goes, practice makes perfect!  I've included the answers so you can see if you need to do some more studying.  With a little practice, all of you should be able to solve any problem in chemistry!
