Points covered in this video:-

Balancing a Chemical Equation:
Step I. Writing unbalanced equation and enclosing the formula.
Ex. Sodium metal reacts with water to produce Sodium hydroxide and
hydrogen gas.

(Na) + (H2O) 🠊 (NaOH) + (H2)

Step II. Making list of number of atoms of different elements as present in unbalanced equation.

Step III. Balancing first element - It is clear that it is only the hydrogen atoms, which are unbalanced. So, firstly try to balance it.

Step IV. Balancing second element - We examine the obtained equation and select another element which is still unbalanced. In the above equation, Na is still unbalanced. To balance the number of Na-atom.

Step V. Checking the correctness of equation - To check the correctness of the equation, we further tabulate the number of atoms of each element separately.

- Propane on combustion gives carbon dioxide and water vapour.
C3H8 + O2 CO2 + H2O
