5g of A reacts with 6 g of B and produces the product AB. If 5 g of A is able to produce -21g AB, given plenty of B, and 6 g of B is able to produce-17 g AB,
given more than enough A, which is the limiting reactant?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
