Steps to Balance an Equation
Practice always makes perfect. In general, to balance an equation, here are the things we need to do:
Count the atoms of each element in the reactants and the products.
Use coefficients; place them in front of the compounds as needed.
The steps are simple, but it is a process of trial and error. Let's take a look at a few more example equations and techniques that can be used to balance each one.
Example 1
This is a reaction between methane (CH4) and oxygen (O2), producing carbon dioxide (CO2) and water (H2O).
Balancing Chemical Equations Example 1
The reaction shown is a combustion reaction: a compound reacts with oxygen and produces carbon dioxide and water. The technique is to balance the carbon (C) atoms first, then the hydrogen (H) atoms, and then the oxygen (O) atoms.
In this case, the carbon (C) atoms are already balanced. So now we look at the hydrogen (H) atoms. There are 4 hydrogen (H) atoms on the reactants side and 2 hydrogen (H) atoms on the products side. To balance them, we put a coefficient of 2 in front of H2O.
Balancing Chemical Equations Example 1
The hydrogen (H) atoms are now balanced. Due to the coefficient 2 in front of H2O, there are a total of 4 oxygen (O) atoms on the products side. To balance the oxygen atoms on both sides, we put a coefficient of 2 in front of O2. The chemical equation is now balance.
