Question

what happens when a piece of carbon is burnt in air​

Answer 1

Answer:

Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide), CO2. Diamond is a form of carbon and also burns in air when heated to 600-800°C - an expensive way to make carbon dioxide! When the air or oxygen supply is restricted, incomplete combustion to carbon monoxide, CO, occurs.
