Question.
Calculate the amount of carbon dioxide that could be produced when
(i)1 mole of carbon is burnt in air.
(ii)1 mole of carbon is burnt in 16 g of dioxygen.
(iii)2 moles of carbon are burnt in 16 g of dioxygen
Calculate the amount of carbon dioxide that could be produced when
(i)1 mole of carbon is burnt in air.
(ii)1 mole of carbon is burnt in 16 g of dioxygen.
(iii)2 moles of carbon are burnt in 16 g of dioxygen
Solution:
The balanced reaction of combustion of carbon can be written as:
(i) As per the balanced equation, 1 mole of carbon burns in1 mole of dioxygen (air) to produce1 mole of carbon dioxide.
(ii) 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.
(iii) According to the question, only 16 g of dioxygen is available. It is a limiting reactant. Thus, 16 g of dioxygen can combine with only 0.5 mole of carbon to give 22 g of carbon dioxide
