Since oxygen is an element, that would depend on whether you mean adding an oxygen atom or an oxygen molecule. Individual oxygen atoms don't seem to like being single; craving partnership, they will pair off or seek out another strong bond. (Think of oxygen atoms like a parakeet that always chirps at himself in the mirror, or an insanely narcissistic person who is phobic about being alone.)
Carbon dioxide (CO2) is a molecular compound made of 1 carbon atom and 2 oxygen atoms, while the oxygen (O2) that we breath is actually a molecule composed of a pair oxygen atoms. Both are stable molecules that are happy to exist without the overbearing need to bond with another element or compound Adding an oxygen atom to CO2 would make "carbon trioxide" (CO3) by name (and according to wikipedia, can be made by blowing ozone at dry ice) but is an unstable molecule which will break down. Due to the arrangement of electrons in the carbon and oxygen atoms, three (CO3) carbon trioxide molecules will rearrange as 3(CO) carbon monoxide molecules and 3(O2) oxygen molecules very quickly because the oxygen prefers to pair up with itself or carbon alone instead of hanging out in a group.
Adding an O2 molecule to CO2 would produce "carbon tetraoxide" (CO4), but you would only see this combination as a sub-grouping in a larger molecule. Carbon atoms are secure enough to hang out with one oxygen couple, but might feel uncomfortable with two unless there were other guests at the party as well!
carbonates
No. Water is a compound of oxygen and hydrogen. Carbon and oxygen will combined to form carbon dioxide or carbon monoxide.
Inside a catalytic converter they are combined with oxygen to form carbon dioxide and water.
There's not much oxygen on any planet except Earth. I mean "free" oxygen, not chemically combined with other elements. Obviously carbon dioxide contains oxygen combined with carbon, for example.
2 atoms of oxygen combined with 1 atom of carbon make up carbon dioxide, which makes it a compound.

carbon and oxygen
Gold is made up of one particle: just pure Gold. Carbon Dioxide however is made up of Carbon AND Oxygen. Carbon and Oxygen are both elements, but when they are combined in this way it is known as a compound.
Carbon is combined with oxygen forming carbon dioxide.
carbon hydroxide
Carbon dioxide is combined with two oxygen atoms to help plants engage in photosynthesis. During this process, plants take in carbon dioxide from the air and convert it into sugars and oxygen with the help of sunlight.
Inside a catalytic converter they are combined with oxygen to form carbon dioxide and water.
an oxidation
Carbon dioxide is a compound. It is made up of two elements, carbon and oxygen, chemically combined in a fixed ratio.
CO - Carbon Monoxide (only one molecule of oxygen). Not to be confused with CO2 - Carbon DIoxide (two molecules of oxygen).
