10 moles of C6H12 reacted with 18 moles of O2, how many moles of CO2 will produce?(a) 3(b) 6(c) 9(d) 12The question was asked at a job interview.Question is from Stoichiometry Applications Terminology in chapter The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering

Answer»

Right choice is (d) 12

Easy explanation: The BALANCED chemical REACTION is C6H12 + 9O2 -> 6CO2 + 3H2O, => O2 is the LIMITING reagent, => MOLES of CO2 = (18/9)*6 = 12.
