Because water has physical and chemical properties that ARE DISTINCT from hydrogen and oxygen.........

Explanation:

What is the normal boiling point of water? What are the normal boiling points of dioxygen; of dihydrogen? (You will have to look these up!). What are the densities of each substance under standard conditions? Different physical and chemical properties specify different chemical substances.
