You Will Need
- An unbalanced chemical equation
- A pencil
Count the number of atoms of each type
Determine how many atoms of each type are on each side of the equation.
Find a starting element
Find an element that is in only one compound on the left side and in only one on the right side of the equation.
Balance the equation for the first element
Multiply the chemical compound on the side that has less atoms of that type by the number required to achieve the same value on the other side.
Select another element or compound that is not balanced and balance it.
Repeat as necessary
Repeat this process until the equation is completely balanced.
Clear any fractions
Eliminate any fractions in the balanced equation by multiplying through by the denominator of the fraction.
