THE LAW OF CONVERSATION OF MASS

The law of conversation of mass is the idea that matter(the thing the universe is made of) cannot be created or destroyed. So, any equation must have the same amount of matter on each side. This is a balanced equation. It means that the equation can and will happen on earth, as in rust, digestion, COMBUSTION, and many other natural chemical changes.

Balanced

The equation above(combustion) is balanced because both sides of the equation have the same amount of total elements. To find out if an equation is balanced, separate the reactant's elements and write them under the equation. BE SURE TO USE COEFFICIENTS AND SUBSCRIPTS!!! Then do the same thing to the products. Compare your answers, do both sides have the same amount of Elements?? If so, it is a balanced equation.
