Question

Decay of organic matter is a chemical change. Justify​

Answer 1

Answer:

Decomposition, the opposite of combination, occurs when a single substance breaks down into two or more different substances. This type of chemical change is evident when fruit decomposes over time. Decomposition can also occur when substances absorb energy, such as the decomposition of water into hydrogen and oxygen with electricity.

Answer 2

Decay of organic matter is a chemical change because:

• A chemical change is one in which the formation or breaking of a chemical bond takes place between the molecules.
• Decaying is the process of rotting or decomposing organic matter through the action of microorganisms like bacteria and fungi.
• In this process, a chemical change occurs in organic matter like carbohydrates, sugars, lipids, etc., and is converted into smaller molecules.
• For example, when fruit begins to rotten it is called a chemical change. This is because sugars present in fruits are converted into substance  by microorganisms which is also responsible for the foul smell.
