Explanation:

Compound consist of molecules that are identical, this molecules are made up of atoms of two or more elements.

An element is identified based on the atomic property of the element.

Water as a compound is composed of 2 Hydrogen atom to 1 oxygen atom and the molecule is H2O.

Water is composed of molecules hence, they are called molecular compound.

Chemical equation of water is showing elements that it is made up of is

H+ + OH- --- H2O .
