Chemical Reactions and Equations

The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction.
A chemical reaction is a process in which one or more substances are converted into new substances.
A chemical equation is a symbolic representation of a chemical reaction, with reactants on the left and products on the right, separated by an arrow.
The purpose of balancing a chemical equation is to ensure that the number of atoms of each element is the same on both the reactant and product sides.
In a chemical equation, the substances to the left of the arrow are called reactants, and the substances to the right of the arrow are called products.
