How to balance a chemical reaction

Write the unbalanced chemical equation next you’ll have to determine how many atoms of each element are present on each side. Add coefficients to balance mass. Last is to add coefficients to oxygen and hydrogen atoms The reason is that they usually appear in multiple reactants and products, so if you tackle them first you’re usually making extra work for yourself. Now, look at the equation to see which coefficient will work to balance oxygen.
