Calculate the amount of carbon dioxide that could be produced when
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
