Worksheet: Thermal Decomposition of Carbonates

In this worksheet, we will practice identifying carbonates susceptible to thermal decomposition and writing balanced equations for these reactions.

Q1:

Which of the following is not a product of the thermal decomposition of a metal carbonate?

  • A A metal oxide
  • B Carbon dioxide
  • C Water

Q2:

A pure sample of calcium carbonate is heated until no further changes in mass are observed. The total change in mass is 30 g. What is the initial mass of the sample?
