Chapter 5, Problem 185MP

Consider the following balanced chemical equation:

$\text{A}\text{+}\text{5B}\to \text{3C}\text{+}\text{4D}$

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 81.7 1% carbon by mass. Determine its empirical and molecular formulas.
