Question

Which of the following classification of matter includes material that can no longer be identified by their individual properties?
A. Compound
B. Element
C. Mixture
D. Atom

Answer 1

Answer: Option (A) is the correct answer.

Explanation:

A substance that consists of two or more elements which are chemically combined together and cannot be distinguished by individual properties of its elements is known as a compound.

For example, water is a compound and has chemical formula $H_{2}O$. Water is non-flammable and non-combustible in nature whereas its elements hydrogen is extremely flammable and oxygen supports combustion.

Thus, we can conclude that in a compound classification of matter includes material that can no longer be identified by their individual properties.

Answer 2

A compound consists of 2 or more elements that are combined chemically in such a way that the elements themselves can no longer be identified by their individual properties. So the Answer is A.
