How much CO_{2} is produced on heating of 1 kg of carbon?

- 11/3 kg
- 3/11 kg
- 4/3 kg
- 3/4 kg

**Answer**

Balanced chemical equation for heating of carbon is

C + O_{2} → CO_{2}

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 CO_{2}

1 g of C = 11/3 g of CO_{2}

1 kg of C = 11/3 kg CO_{2}

**The correct option is A.**
