उत्तर

The balanced reaction of combustion of carbon can be written as:-

\[\ce{\underset{1 mole}{C_{(s)}} + \underset{(32 g)}{\underset{1 mole}{O_{2(g)}}} -> \underset{(44 g)}{\underset{1 mole}{CO_{2(g)}}}}\]

According to the question, only 16 g of dioxygen is available. Hence, it will react with 0.5 mole of carbon to give 22 g of carbon dioxide. Hence, it is a limiting reactant.
