Guidelines for Balancing Chemical Equations

May 28, 2013Balance the equation. Apply the Law of Conservation of Mass to get the same number of atoms of every element on each side of the equation. Tip: Start by balancing an element that appears in only one reactant and product. Once one element is balanced, proceed to balance another, and another, until all elements are balanced. Balance chemical formulas by placing coefficients in front of them. Do

Some Easy Tips for Balancing Chemical Equations

When you write a chemical equation, a necessary step is to balance the number of atoms on both sides of the equation. For example, in the above reaction one molecule of hydrogen (H 2) and an atomic form of oxygen (O) are sufficient to produce a molecule of water (H 2 O). But it is hard to find atomic oxygen.
