Thermal decomposition

The video explains thermal decomposition, a process where substances break down when heated. It uses calcium carbonate as an example, which decomposes into calcium oxide and carbon dioxide. The process is typically endothermic, meaning it absorbs heat.

What are the products of the thermal decomposition of calcium carbonate?

• Calcium oxide and carbon dioxide

• Calcium and oxygen

• Calcium and carbon

• Calcium oxide and oxygen

Explain why thermal decomposition is considered an endothermic reaction.
