Question

Q2. In limited supply of air charcoal burns
to form carbon dioxide gas, Explain it.​

Answer 1

Actually, when charcoal burns in excess of air, only then we get CO2 gas. When supply of air is limited, we get CO. When there is limited supply of air, only half of the oxygen gets added, and hence forms CO. Else, (i.e when supply of air is excess), then CO2 will be formed.
