Question

Consider the following balanced chemical equation: A + 5B → 3C + 4D
a. Equal masses of A and B are reacted. Complete each of the following with either “A is the limiting reactant because _____”; “B is the limiting reactant because _____”; or “We cannot determine the limiting reactant because _____.”
i. If the molar mass of A is greater than the molar mass of B, then
ii. If the molar mass of B is greater than the molar mass of A, then
b. The products of the reaction are carbon dioxide (C) and water (D). Compound A has a similar molar mass to carbon dioxide. Compound B is a diatomic molecule. Identify compound B and support your answer.
c. Compound A is a hydrocarbon that is 81.71% carbon by mass. Determine its empirical and mo­lecular formulas.
