GC Atomic Structure

How much CO2 is produced on heating of 1 kg of carbon?

  1. 11/3 kg 
  2. 3/11 kg
  3. 4/3 kg
  4. 3/4 kg

Answer

Balanced chemical equation for heating of carbon is

C + O2 → CO2

From the equation, 12 g of carbon reacts with 32 g of oxygen to produce 44 g carbon dioxide.

12 g of C gives 44 g of CO2

1 g of C = 11/3 g of CO2

1 kg of C = 11/3 kg CO2

The correct option is A.
