1.	Find the amount of carbon dioxide produced by the combustion of 20g of methane.(a) 44g(b) 20g(c) 66g(d) 22gI got this question during a job interview.Origin of the question is Stoichiometry and Stoichiometric Calculations in section Chemistry Basic Concepts of Chemistry – Class 11
Answer» The correct choice is (c) 66g The explanation is: The CHEMICAL balanced equation for combustion of methane is CH4(g) + 2O2(g)→CO2(g) + 2H2O(g). From the above equation, 1 mole of methane GIVES 1 mole of carbon dioxide. But 20G of methane = 1.25 moles, therefore it gives 1.25 moles of carbon dioxide = 44(1.5) = 66g.
