Question - 0.1

Identify balanced chemical equations from the following.

(1) C + O2 → CO2

(2) H2+O2 →H2O

(3) 2Pbo +C → Pb + CO2

(4) Fe2O3 + 2A1→ AL2O3 + 2Fe

(a) All of above are balanced.

(b) (1), (3),and (iv) are balanced.

(C) (1) and (iv) are balanced.

(d) (1),(2) and (iii) are balanced.

Balanced chemical equation is - (C) (1) and (iv) are balanced.

Balanced chemical equation refers to the equation where amount of product formed is equal to the amount of substrate consumed. In balanced chemical equation, number of moles of each element should be equal on both sides of equation.

The balanced chemical reaction will be -

2H2 + O2 --> 2H2O

In this reaction, 2 moles of hydrogen and 1 mole of oxygen is present on left sides and 2 moles of water on right side.

2PbO + C --> 2Pb + CO2

In this reaction, 2 lead oxide, 1 carbon mole is present on left side and 2 moles of lead and 1 mole of carbon dioxide on right side.
