What is the first step in balancing a chemical equation? Rules of balancing chemical equations: 1. write the unbalanced equation 2. count the number of atoms of the same element on reactant and product side of equation 3. make the â¦ number of atoms the same by changing the coefficients, not subscripts 4. balance hydrogen and oxygen last 5. reduce coefficients if possible
Balanced Chemical Equation  Tells us which substances are the products and which substances are the reactants, and the relative amounts of each. Balancing Chemical Equations. In class demo Electrolysis of Water. The reaction that is taking place right now is the decomposition of water into hydrogen and oxygen.Water Hydrogen + Oxygen. In this example water is the reactant (it will be completely destroyed if the reaction goes to completion), while hydrogen and oxygen are the products (they are created by this chemical reaction).alanced Chemical Equation  Tells us which substances are the products and which substances are the reactants, and the relative amounts of each.
