WebOct 28, 2024 · Chemical Equations = Reactions Because a chemical equation represents a chemical reaction, it's important to understand what a chemical reaction is. You observe chemical reactions... WebAll chemical equations must be balanced. This means that there must be the same number of each type of atom on both sides of the arrow. To balance a chemical equation, place coefficients as needed in front of the symbols or formulas so the same number of each type of atom occurs in both reactants and products.
