• 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.
