Question

The properties of water are different from properties of elements of which it is formed.discuss

Answer 1

The constituent elements of water are hydrogen and oxygen.
Hydrogen is an inflammable substance, i.e it burns. Whereas oxygen supports burning. These properties are completing different from that of water, which extinguishes fire.

Answer 2

Answer:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions. Example: water $H_2O$

$2H_2(g)+O_2(g)\rightarrow 2H_2O(l)$

Compounds have different properties as compared to the constituents from which it is made.

Hydrogen is a gas , oxygen is a gas whereas water formed is in liquid state.

Also hydrogen does not support combustion, oxygen supports combustion whereas water stops combustion.
