Chemical reactions are happening all around us and even within us. They occur in your brain and everywhere else in your body as you read this. A large part of chemistry is about understanding reactions and the reactants & products involved. Chemical equations are how chemistry and chemical engineers visualize chemical reactions between elements, compounds, and the like.

Practical Tips to Balance Chemical Equations
Trial-and-error is one of the most common methods for balancing chemical equations. This is where you try out different coefficients with every reactant and product. The ones that balance both sides are the balancers.
The trial-and-error method, or the inspection method, works fine for most chemical reactions. However, a more structured approach is necessary for equations involving several reactants and complex, multi-stage reactions.
Count all the elements on both sides of an equation before starting. Take note of the most unbalanced ones.
Ensure all the symbols and formulas of all reactants and products are correct. Check and recheck.
Balancing equations is no big deal. You need to use your basic mathematical skills to balance out elements on both sides.
Always try to reduce the coefficients to their lowest multiple.
Correct chemical equation balancing occurs when you have the smallest ratios of the coefficients on both sides of the equation.
Now, let’s take a look at some examples.
Some Elaborative Examples
Consider the following chemical compound, C3H6O2. The chemical name of this compound is methoxyacetaldehyde. When it undergoes combustion, the following reaction occurs à
C3H6O2 + O2 à CO2 + H2O
As evident, the above equation needs to be balanced. Let’s balance it out.
Initially, we find that carbon and hydrogen get balanced if we put 3 as the carbon dioxide and water coefficients.
C3H6O2 + O2 à 3 CO2 + 3 H2O
But, if we do so, oxygen becomes unbalanced. We find that there are 9 oxygen atoms on the right-hand side and 4 on the left-hand side.
If we put 3.5 in front of the oxygen molecule, everything balances out.
C3H6O2 +3.5 O2 à3 CO2 + 3 H2O
We can also balance the entire equation in the following manner à
2 C3H6O2 + 7 O2 à 6 CO2 + 6 H2O
Remember always to use whole numbers and not fractions to balance chemical equations. The general rule is to use the lowest whole-number ratio.
However, you can use fractions to balance an equation if there are no whole number ratios.
Balancing chemical equations is not hard if you put your mind to it. However, if time becomes a factor, here are the top 5 automated online chemical equation balancing tools.
