Question: 55

10. Which of the following types of reactions generally have the same number of reactants and products?

I. Double-displacement reactions

II. Single-displacement reactions

III. Combination reactions

  • A. I only
  • B. II only
  • C. I and II only
  • D. II and III only

Correct Answer: C

Explanation:

Typically, both single-displacement and double-displacement reactions have two reactants that swap either one or two components between the two species. Combination reactions, on the other hand, have more reactants than products because the reactants combine together to form the product.
