Question: what is meant by thermal decomposition reaction give two examples of thermal decomposition reaction?
Answer: A thermal decomposition reaction occurs when heat is applied to a compound causing it to decompose (break down) into multiple different chemical substances. An example is when baking soda (sodium bicarbonate) is heated. 2NaHCO3(s)→CO2(g)+H2O(g)+Na2CO3(s) Here is a video discussion of this reaction.
