How to Balance Chemical Equation?

Chemical equation is defined as the symbolic representation of the chemical reaction. Here, we are giving the detailed step by step procedure that to be followed while balancing any chemical equation.

  • Let us assume any chemical equation
  • At first count the number of each and every atoms on right hand side and left hand side of the equation
  • Add numbers to the reactants and products to make the number of items on both sides are equal.
  • Cancel the common terms in denominator, numerator


Question1: Balance the following chemical equation C2H6+O2->CO2+H2O?


Given chemical equation is


In the given equation we have 2 Carbon items, 6 Hydrogen and 2 Oxygen items at one side.

The other side of the equation has one Carbon, 2 Hydrogen and 3 Oxygen

By seeing the equation, we have to balance carbon and oxygen numbers

To balance the Carbon items just add 2 in front of CO2 but oxygen items are not balanced

So add 4 in front of CO2 and 6 in front of Water (H2O)

The equation becomes


Question2: Balance the equation H2+O2->H2O?


Given Chemical equation is


Two Hydrogen and 2 Oxygen items on one side and two Hydrogen and one Oxygen on the other side of the equation.

So, we need to balance the Oxygen items only.

FAQs on Chemical Equation Calculator

1. What are the different types of chemical reaction?

The different primary types of chemical reactions are as listed here

Combination reaction

Displacement reaction

Decomposition reaction

Double displacement reaction

2. What are the steps involved in writing a chemical equation?

The steps involved in representing a chemical equation are mentioned here:

The reactants are written on the left hand side and products are written on the right hand side of the equation

An arrow pointing towards the products is inserted between the reactants and products.

Arithmetical plus sign is inserted between the products, reactants.

3. What are the parts of a chemical equation?

Each and every chemical equation should have these parts. They are Reactants, Products, Coefficients, Subscripts, Arrow, and Law of Conservation of Mass.

4. What are the examples of chemical equation?

In general, chemical changes involve chemical equation and the creation of new products. Chemical changes are irreversible. The common chemical changes observed in human life are Burning Wood, Boiling Egg, Baking a Cake, Rotting Bananas, Using a chemical battery, and others.

5. What are the main differences between chemical change and physical change?

Chemical change is a permanent change where physical is a temporary change. Physical change affects only physical properties i.e shape, size, colour but chemical change affects both physical and chemical properties. The best examples of chemical changes are boiling egg, burning of coal, for physical changes are melting wax, boiling of water and freezing of water.
