Question

10g of H2 react with 64 g of O2 to yield H2O.

a) Which is the limiting reagent?
b) Calculate the maximum amount of H2O that can be formed.
c) Calculate the amount of one of the reactant which remains unreacted.

Answer 1

Answer:

Typically, percent yields are understandably less than 100% because of the reasons indicated earlier. However, percent yields greater than 100% are possible if the measured product of the reaction contains impurities that cause its mass to be greater than it actually would be if the product was pure.
