Answer 1

Explanation:

The two forms of oxygen found in the atmosphere are diatomic molecular form that has chemical formula O2 or OXYGEN,the- lifegiving gasthat we breadth in to survive.

Another is a triatomic molecular form that has chemical formula O3 called OZONE GAS ,it protect us from harmful UV rays.In water, oxygen is found as a compound with hydrogen molecules.The oxygen in water is dissolved oxygen used by aquatic animals and plants.

Carbon dioxide has 2 molecules of oxygen with one molecule of carbon.It is formed by the reaction between carbon molecules and oxygen molecules during fermentation or respiration.In the case of water and carbon dioxide, the oxygen doesnot exist independently but in association with other molecules.whearas in the case of OZONE and oxygen, the oxygen exist independently .Hence,the two forms of oxygen are ozone and oxygen.
