Greetings, and welcome to the world of stoichiometry!

Stoichiometry is basically one of the cornerstones of chemistry, since it is the study of the fundamentals of chemistry.

It provides the rules needed to construct the formula of chemical compounds, to construct balanced chemical equations, and to provide procedures to calculate the mass or volume or concentration, of a reactant or a product, using the mole concept.

As a result, you get to know the chemical compounds better, chemical reactions and experiments become more accurate, which is needed in manufacturing and analysis.

No surprise that some students find this particular topic a tough one, but no need to worry, you are here so that the tough topic becomes a piece of cake.

And remember, your performance does not stop here, so it is encouraged to keep on practicing.

This practice test consists of three parts:

1- Ability to write chemical formula based on the chemical compound's name, and ability to deduce the chemical compound's name based on the written formula.

2- Ability to construct balanced chemical equations.

3- Understanding the mole concept and its related calculations.

Do not forget to get the required tools (calculator, periodic table), to help you with the tasks.

So, get yourself ready, and have fun learning.
