Questions 40 and 41 all REFER TO THE PROBLEM BELOW!
When chlorine gas is added to acetylene gas, liquid 1,1,2,2-tetrachloroethane is formed:
2 Cl2(g) + C2H2(g) ⟶ C2H2Cl4(l)
40. If 8.0 L of chlorine is reacted at STP, exactly how many liters of acetylene at STP would be needed to allow complete reaction?
39. If one of my Chem 10 students ran the reaction as stated in problems 35 and got 7.052 g of Ba(OH)2, what is the percent yield for the reaction?
38. Referring to question 37, which reactant was the limiting reactant?
