Chemistry is pretty much about math and logic. So, if you’re good with those, you’ll be able to understand how chemical reactions work and what they’re made of. For instance, chemical equations are like recipes that show how a chemical reaction happens. And if you don’t balance them, you’re breaking the rules of conservation of mass and energy.

Balancing a chemical equation can be a real challenge, especially when you’re short on time. But fear not! This is a handy chemical equation calculator that can help you out. It’s super fast and accurate, so you can save yourself a lot of trouble.

Let’s dive into the features of this fantastic chemical equation balancer & calculator, but a bit before that let’s see what is a chemical reaction.

Before we read about the chemical equation calculator, let us first understand what a chemical equation is. In chemistry, an equation is basically the symbolic representation of a chemical reaction. According to the law of conservation of mass, atoms are neither created nor destroyed during a chemical reaction. What occurs during a chemical reaction is the rearrangement of atoms. In a chemical equation, the reactants and products are conventionally shown on the left and right sides of an arrow, respectively.

Obeying the laws of conservation of mass and charge, both the numbers of every type of atom and the total charge have to be the same on both sides of a balanced chemical equation. The only difference on each side of the equation is the arrangement of the atoms to form ions or molecules. That is because in a reaction, usually the reactants’ bonds are broken and new bonds are to give rise to the products. If the numbers of each kind of atom on the two sides of an equation are different, then the reaction is unbalanced. As a result, it fails to correctly represent what takes place during the reaction.

For example, consider the example given below:

CH4 + Cl2 → CCl4 + HCl

The balanced chemical equation for the above reaction is:

CH4 + 4Cl2 → CCl4 + 4HCl

Using a chemical equation, we can also determine the equilibrium constant of the reaction (Keq). It is defined as the value of a reaction’s reaction quotient at the state of chemical equilibrium. The Keq of a reaction is formulated as the amount of products divided by the amounts of reactants. Here, each amount is in terms of either the concentration or partial pressure, raised to the power of its coefficient in the balanced chemical equation.

There are many ways of manually balancing a chemical equation. However, these methods tend to be time-consuming and, occasionally, complicated. The chemical equation calculator is of great help to students, teachers, and scientists who need to balance a chemical equation accurately and speedily.

The chemical equation calculator has been programmed with a state-of-the-art algorithm to ensure accurate results in a short time. It is highly recommended for beginners and professionals alike.

Balance a Chemical Equation Manually

Not everything has to be done with a chemical equation balancer & calculator. In the exams, you will have to do it manually and on paper.

Balancing a chemical equation involves determining the correct number of atoms of each element that are involved in a chemical reaction.

The reactants (the starting materials) must be balanced with the products (the materials formed in the reaction) regarding the number of atoms of each element present. To balance a chemical equation, you can follow these steps:

  1. Write the unbalanced equation with the reactants on the left side and the products on the right side.
  2. Identify the elements that are present in the reactants and the products.
  3. Determine the number of atoms of each element present in the reactants and the products.
  4. If the number of atoms of an element on the reactant side does not match the number of atoms on the product side, add a coefficient (a number in front of a chemical formula) to balance the number of atoms.
  5. Check that the equation is balanced by ensuring that the number of atoms of each element is the same on both sides.

For example, the balanced chemical equation for the combustion of methane (CH4) is:

CH4 + 2O2 → CO2 + 2H2O
