Limiting Reagent — Quiz

Test your understanding of limiting reagent with 5 practice questions.

Practice Questions

Question 1

Which reagent is limiting when 2.50 g of Zn reacts with 10.0 g of AgNO3 according to Zn + 2 AgNO3 → Zn(NO3)2 + 2 Ag?

Question 2

What is the theoretical yield of Ag in grams for the reaction in Question 1?

Question 3

If the actual mass of Ag obtained is 11.0 g, what is the percent yield of the reaction?

Question 4

Calculate the mass of unreacted Zn remaining after the reaction in Question 1.

Question 5

In the thermal decomposition CaCO3 → CaO + CO2, if 20.0 g of CaCO3 yields 7.50 g of CO2, what is the percent yield?
