Vedclass · Answer

(C) During the early stages of the Earth's formation,the atmosphere was reducing. As free oxygen was produced,it reacted with the abundant hydrogen and methane present in the primitive atmosphere. The reaction of oxygen with hydrogen formed water $(H_2O)$,and its reaction with methane $(CH_4)$ and ammonia $(NH_3)$ led to the formation of carbon dioxide $(CO_2)$ and other complex compounds. Therefore,oxygen combined with hydrogen,methane,and ammonia to form these essential molecules.

Oxygen combined with which of the following to form water,carbon dioxide,and other compounds during the early evolution of the Earth?
