Problem- Ethyl acetate reacts with H2 in the presence of a catalyst to yield ethyl alcohol- C4 H8O2(l) +H2(g)-------> C2H6O6(l)
Part a) Write a balanced equation for the reaction.
Part b) How many moles of ethyl alcohol are produced by reaction of 1.5 mol of ethyl acetate?
Part c) How many grams of ethyl alcohol are produced by reaction 1.5 mol of ethyl acetate with H2?
Part d) How many grams of ethyl alcohol are of ethyl alcohol are produced by reaction of 12.0 g of ethyl acetate with H2?
Part e) How many grams of H2 are needed to react with 12.0g of ethyl acetate?
