<h3>What is a balanced equation?</h3>
A balanced chemical equation is a chemist's shortcut for representing the molecules and atoms involved in a chemical process using chemical symbols. On the left side of the equation are the reactants, and on the right are the products. The number of molecules involved is indicated by the coefficients, and the number of atoms in each molecule is indicated by the subscripts.
Based on the interactions of the constituent chemicals, knowledge of the law of conservation of mass, and practise with a few example equations, chemical equations can be "balanced," much like algebraic equations.
