Question

water have hydrogen and oxygen two substance then why this is this is a pure matter? ​

Answer 1

HERE IS UR ANSWER MATEY !!!!

A mixture is when two or more substances combine physically together.

However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.

For example, if you combine iron powder and sulfur powder physically (just mixing them together without applying heat), you can find that the mixture retains the properties of the original components, i.e. you can still use a magnet to attract the iron inside the mixture.

However, if you heat it up, the iron and the sulfur would combine chemically, and a new compound would be formed, which we call "iron sulfur" (FeS). This is a new compound and loses the properties of the original compounds. For example, it is not attracted by magnets.

Therefore, water is not a mixture; it is a compound and it is pure.

HOPE THIS HELPS U

Answer 2

Answer:

hydrogen and oxygen will together make up water. However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.

Explanation:

Water can be pure water and not always pure because minute substances can mix with water and this makes water impure.
