Chemical equations are illustrations of the reactants and products in a chemical reaction. Chemical equations are expressed as A + B - C, where A and B are the reactants, and C is the product. More »

The chemical equation for the combustion of hydrogen is 2H2 + O2 → 2H2O. During hydrogen combustion, the heat from burning makes hydrogen chemically react with oxygen gas, O2, in the air to form water. More »

The chemical equation formula for water is expressed as H2O, but also is acceptable when displayed as HOH. In this equation, two hydrogen atoms react with an oxygen atom to form a single molecule of H2O. More »

A chemical reaction occurs when the reactants break into constituent ions and recombine to form different products. In this case, lead nitrate and potassium chromate recombine to form lead chromate and potassium nitrate.... More »

Skeleton equations are created by placing the reactants, separated by plus signs, on the left-hand side, and the products on the right-hand side. These skeleton equations are generally unbalanced because they imply that ... More »

Stoichiometry is a branch of chemistry that deals with the relationship between reactants and products involved in a chemical reaction. In other words, it deals with calculations of masses or volumes of relative quantiti... More » Science Chemistry Chemical Equations

It is important to balance chemical equations because there must be an equal number of atoms on both sides of the equation to follow the Law of the Conservation of Mass. This chemical law states that in order for the equ... More »
