Answer:

1. a = 2, b = 1 and c = 2

2. a = 1, b = 3, c = 2 and d = 2

Explanation:

According to law of conservation of mass, the mass can neither be created nor destroyed.

Hence, for a chemical equation the left hand side should be equal to the right hand side.

Therefore, the two balanced equations are;

2 CO + O₂ → 2 CO₂

C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O
