Question

How to balance a chemical equation?​

Answer 1

HOW TO BALANCE A CHEMICAL EQUATION :-

Step 1: Write the equation to be balanced.

For example: H2 + O2 ⟶ H2O

Step 2: Write the number of molecules of each element in the equation.

For example: LHS | RHS

H = 2 | H = 2

O = 2 | O = 1

Step 3: Equalize the equation one by one.

For example:

Hydrogen are already equalised.

➢ H2 + O2 ⟶ 2H2O

Now, oxygen are equal but hydrogen are unequal.

➢ 2H2 + O2 ⟶ 2H2O

Now, everything in the equation is equal.

RHS | LHS

H = 4 | O = 2

H = 4 | O = 2

Hence, the equation is balanced.
