Questions & Step-by-Step Solutions

What is the primary product of the thermal decomposition of calcium carbonate? (2019)
  • Step 1: Understand what thermal decomposition means. It is a process where a compound breaks down into simpler substances when heated.
  • Step 2: Identify the compound in the question, which is calcium carbonate (CaCO3).
  • Step 3: Know that when calcium carbonate is heated, it breaks down.
  • Step 4: Determine the products of this breakdown. Calcium carbonate decomposes into calcium oxide (CaO) and carbon dioxide (CO2).
  • Step 5: Conclude that the primary products of the thermal decomposition of calcium carbonate are calcium oxide and carbon dioxide.
