Answer 1

Answer:

Decomposition reactions

are processes in which chemical species break up into simpler parts. Usually, decomposition reactions require energy input. For example, a common method of producing oxygen gas in the laboratory is the decomposition of potassium chlorate (KClO3) by heat.

Decomposition Reaction Examples

Carbonic acid in soft drinks decomposes to give carbon dioxide gas. Hydrogen gas and oxygen gas are released from the decomposition of water. Digestion of food is a decomposition reaction. Through this reaction, nutrients are released from the food eaten.

Answer 2

Answer:

Decomposition reaction is a chemical reaction in which a single compound breaks down to simpler products. ... Example: Decomposition of ferrous sulphate crystals. 2FeSO4 (s) → Fe2O3 (s) + SO2 (g) + SO3 (g) Heat the ferrous sulphate crystals; the colour of ferrous sulphate crystals is green.
