उत्तर
The balanced reaction of combustion of carbon can be written as:-
\[\ce{\underset{1 mole}{C_{(s)}} + \underset{(32 g)}{\underset{1 mole}{O_{2(g)}}} -> \underset{(44 g)}{\underset{1 mole}{CO_{2(g)}}}}\]
As per the balanced equation, 1 mole of carbon burns in 1 mole of dioxygen (air) to produce 1 mole of carbon dioxide.
