Module 6 - Practice Problems

QuestionAnswer
6.1 When 2.13 moles of C^3H^8 burn in excess oxygen, how many moles of CO^2 will be formed? Assume this is complete combustion. 6.39 moles CO₂
6.2 Silver tarnishes when exposed to oxygen and dihydrogen monosulfide. The chemical reaction is on p. 199. 0.000164516 moles H₂0
6.3 Freon, a very useful refrigerant, is produced in the reaction on p. 199. If a chemist wants to make 1.0 x 10(4) moles of Freon using excess carbon tetrachloride, how many moles of antimony triflouride will the chemist need? 9944.44 moles
6.4 In the reaction from problem #3, suppose the chemist wanted to make 100.0 liters of Freon using exess antimony triflouride. How many liters of carbon tetrachloride would the chemist need? 99.44 liters
6.5 17,908.16 grams
6.6 13.61 grams
