The most common state of oxygen is probably oxygen combined with metals and silicon such as molecules of silica which is sand and molecules of metal oxides like iron oxide. Aluminium oxides and Iron oxides and many other metal oxides make up most of the rocks and heavy material in the earth's crust. The sea contains a lot of oxygen as H2O which is water and the air is 20% oxygen, but the earth's crust weighs a lot more than the oceans and the air put together.
Therefore it is very likely that the rocky oxides hold most of the Earth's oxygen.
Carbon monoxide CO; and carbon dioxide CO2.
The most common form of answer is Carbon-die-oxide and Carbon-mon-oxide.
solid
Carbon is a chemical element; methane (CH4) is a chemical compound containing carbon.
The chemical formula of carbon monoxide is CO.
Water: H2OFrizz bubbles, carbon dioxide: CO2Ammonia: NH3Table salt: NaClNatural gas, methane: CH4Alcohol, ethanol: C2H5OHTable sugar, saccharose: C12H22O11
Common salt (Sodium Chloride) has the formula NaCl.
The elements are returned back to the atmosphere. It is common in all the cycles.
Carbon is a chemical element; methane (CH4) is a chemical compound containing carbon.

The chemical formula of carbon monoxide is CO.
Carbon Monoxide
Carbon dioxide, methane are the two more common compounds.
Carbon dioxide (CO2)Carbon monoxide (CO)Carbon trioxide (CO3)Carbon tetroxide (CO4).

They are chemical compounds.
Carbon dioxide is a very common gas with the chemical formula CO2.
The elements are returned back to the atmosphere. It is common in all the cycles.
Nitrogen, Oxygen,Hydrogen, and Carbon Di-oxide are the common Gases in the Atmosphere.
