Describe the differences between word equations, formula equations, and chemical equations.

A word equation uses words to represent the reactants and products in a chemical reaction. A formula equation uses chemical symbols or formulas, but does not reveal the ratios of the products and reactants. A chemical equation is a balanced formula equation.

You must be able to write word, formula, and chemical equations
