The chemical equation needs to be balanced so that it follows the law of conservation of mass.
To balance the chemical equation above, we need to make use of coefficients. A coefficient is a number that we place in front of a chemical formula. In the chemical equation, to make the number of nitrogen (N) atoms equal on both sides, first, we place a coefficient of 2 in front of NH3.
Once we do that, the number of nitrogen (N) atoms on both sides is balanced. However, the number of hydrogen (H) atoms is not balanced on both sides. We need to make use of another coefficient in front of H2. This time, we put a coefficient of 3 in front of H2 to balance the chemical equation.
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.
