Limiting Reactant Practice

Front

What is a limiting reactant?

Back

A limiting reactant is the substance that is completely consumed in a chemical reaction, limiting the amount of product that can be formed.

Front

How do you identify the limiting reactant in a chemical reaction?

Back

To identify the limiting reactant, compare the mole ratio of the reactants used in the reaction to the mole ratio required by the balanced equation.

Front

In the reaction Fe + S -> FeS, if 7.62g of Fe and 8.67g of S are used, which is the limiting reactant?

Back

Fe is the limiting reactant.

In a sandwich-making scenario, if you have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, which ingredient is the limiting reactant?

Back

Peanut butter is the limiting reactant.

Front

What is the balanced equation for the reaction of NH3 and NO?

Back

4NH3 + 6NO -> 5N2 + 6H2O.

Front

If 10 moles of NH3 react with 30.0 moles of NO, which is the limiting reactant?

Back

NH3 is the limiting reactant.

Front

In the reaction C10H8 + 12 O2 -> 10 CO2 + 4 H2O, if 12 moles of O2 react with 1.1 mole of C10H8, what is the limiting reactant?

Back

Oxygen is the limiting reactant.

Front

What is the limiting reactant when 20g of CH4 reacts with 15g of H2O in the reaction CH4 + 2H2O -> CO2 + 4H2?

Back

H2O is the limiting reactant.

Front

Why is it important to identify the limiting reactant in a chemical reaction?

Back

Identifying the limiting reactant is important because it determines the maximum amount of product that can be formed in the reaction.

Front

What is the mole ratio of reactants in the reaction 4NH3 + 6NO?

Back

The mole ratio is 4 moles of NH3 to 6 moles of NO.
