Multiple Choice
How do you determine if the problem has a limiting reactant?
There is information about the mass or the moles of two or more reactants.
There are more than one reactant in the reaction.
There are more than one product in the reactions.
All stoichiometry problems are limiting reactant problems.
6
Multiple Choice
Identify if the problem will be a limiting reactant problem:
How many moles of ammonia are formed when 2.00 moles of nitrogen reacts with hydrogen?
It is a limiting reactant problem because the moles of a reactant is given.
It is NOT a limiting reactant problem because the moles of one reactant is given.
It is NOT a limiting reactant problem because the products are given for the reaction.
It is a limiting reactant problem because the moles of two reactants are given.
7
Multiple Choice
Identify if the problem will be a limiting reactant problem:
How many moles of sodium chloride is formed when 45.8 g NaOH reacts with 26.5 moles HCl?
It is a limiting reactant problem because the quantitative values of a reactant is given.
It is NOT a limiting reactant problem because the quantitative values of one reactant is given.
It is NOT a limiting reactant problem because the products are given for the reaction.
It is a limiting reactant problem because the
quantitative values of two reactants are given.
8
Multiple Choice
Identify if the problem will be a limiting reactant problem:
How many grams of iron is needed to react with 97.26 grams of oxygen to form iron(III) oxide?
It is a limiting reactant problem because the quantitative values of a reactant is given.
It is NOT a limiting reactant problem because the quantitative values of one reactant is given.
It is NOT a limiting reactant problem because the products are given for the reaction.
It is a limiting reactant problem because the quantitative values of two reactants are given.
9
Multiple Choice
Identify if the problem will be a limiting reactant problem:
A reaction occurs between a 112.9 grams of cobalt and oxygen. If the reaction starts with 7.2 moles of oxygen, how many grams of cobalt(III) oxide can be formed?
It is a limiting reactant problem because the quantitative values of a reactant is given.
It is NOT a limiting reactant problem because the quantitative values of one reactant is given.
It is NOT a limiting reactant problem because the products are given for the reaction.
It is a limiting reactant problem because the quantitative values of two reactants are given.
