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