What is a balanced equation?
A chemist's shortcut for using chemical symbols to depict the molecules and atoms involved in a chemical reaction is a balanced chemical equation. Reactants are located on the left side of the equation, and products are located on the right. The coefficients show how many molecules are involved, and the subscripts show how many atoms are in each molecule.
Chemical equations can be "balanced," much like algebraic equations, based on the interactions of the constituent chemicals, understanding of the law of conservation of mass, and practice with a few example equations.
