1. Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid-fuel rocket motors. The reaction is: Fe2O3(e) + 2Als) → 2Fem + Al2O3(s) a. How many moles of Fe will be produced when there are 6 moles of Al ? b. What masses of iron(II) oxide and aluminum must be used to produce 15.0 g iron? DDT, an insecticide harmful to fish, birds, and humans, is produced by the following reaction: 2. 2C,H;CI + C,HOCI, C4H,Cls + H20 chlorobenzene chloral DDT In a government lab, 1142 g of chlorobenzene is reacted with 485 g of chloral. a. What mass of DDT is formed? b. Which reactant is limiting? Which is in excess? c. What mass of the excess reactant is left over? d. If the actual yield of DDT is 200.0 g, what is the percent yield?
