Law of Conservation of Mass

INTRODUCTION TO THE LAW OF CONSERVATION OF MASS

The Law of Conservation of Mass states that mass cannot be created or destroyed by chemical reactions or physical changes. 

According to the Law of Conservation of Mass, the mass of the products in a chemical reaction must equal the mass of the reactants. 

BALANCING CHEMICAL EQUATIONS TO FOLLOW THE LAW

The NUMBER AND TYPE OF ATOM must be equal on both the reactants side and products side of a Chemical Equation to ensure that this law is followed .

Typically, you are provided with the reactants and the products of a chemical reaction in the form of a chemical equation. You first need too evaluate many of each kind of atom are involved in allowing the reaction to occur to maintaining the Law of Conservation of Mass.

THIS IS WHERE BALANCING CHEMICAL EQUATIONS COMES INTO PLAY...

7th Grade Students: 

Watch only until 10:12  - Beyond that are examples that are more complicated than you need to worry about!
