What is the main product of the thermal decomposition of calcium carbonate (CaCO3)? (2019)

What is the main product of the thermal decomposition of calcium carbonate (CaCO3)? (2019)

Step 1: Understand what thermal decomposition means. It is a chemical process where a compound breaks down into simpler substances when heated.
Step 2: Identify the compound we are looking at, which is calcium carbonate (CaCO3).
Step 3: Know that when calcium carbonate is heated, it breaks down into two products.
Step 4: The first product formed is calcium oxide (CaO). This is a solid substance.
Step 5: The second product formed is carbon dioxide (CO2). This is a gas that will be released into the air.
Step 6: Therefore, the main products of the thermal decomposition of calcium carbonate are calcium oxide (CaO) and carbon dioxide (CO2).
