Step 1: Determine number of atoms for each element
. Step 2: Pick an element that is not equal on both sides of the equation. Step 3: Add a coefficient in front of the formula with that element and adjust your counts
. Step 4: Continue adding coefficients to get the same number of atoms of each element on each side.
