Describing Chemical Reactions
... To describe a reaction accurately, a chemical equation must show the same number of each type of atom on both sides of the equation. An equation is balanced when it accurately represents conservation of mass. To balance a chemical equation, you may have to use coefficients. A coefficient is a number ...
