Cobalt has an oxidation number of 3 (III) in the compound Co2O3.
The oxidation number of cobalt in Co2O3 is +3, and the oxidation number of oxygen is -2. This is based on the rules for assigning oxidation numbers, where the overall charge of the compound must equal zero.
In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
Co2(CO3)3The chemical formula of cobalt(III) carbonate [not cobalt(111)] is Co2(CO3)3.
Carbon trioxide, also known as carbon sesquioxide, is the chemical name for Co2O3. It is an unstable oxide of carbon and has limited practical applications.

Co2(CO3)3The chemical formula of cobalt(III) carbonate [not cobalt(111)] is Co2(CO3)3.
The formula CoO3 has 4 atoms: 1 cobalt and three oxygen. That said, I'm doubtful that that compound actually exists. CoO and Co3O4 both definitely do, Co2O3 is probable but less certain, but the oxidation states involved in those are all reasonable ones for cobalt; +6 would be unusual to say the least.
Co2O3
Carbon trioxide, also known as carbon sesquioxide, is the chemical name for Co2O3. It is an unstable oxide of carbon and has limited practical applications.
Cobalt(III) oxide is a chemical compound with the formula Co2O3. It is a dark brown solid that is insoluble in water. It is used as a catalyst in chemical reactions and as a pigment in ceramics.
Take into account that oxygen has a negative 2 charge (O-2) and there are 3 of them; therefore, to form this compound Cobalt must have a positive 3 charge (Co3+) because there are 2 of them. The name of this compound is Cobalt (III) oxide or Cobaltic oxide.
The formula of cobaltic oxide hexahydrate is Co2O3·6H2O.
This is half of a question I think. If you meant H2CO3 then its carbonic acid. If you are talking about bacteria, then it may be the ID code for a strain of Salmonella, (very bad to eat).
