Cobalt has an oxidation number of 3 (III) in the compound Co2O3.
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.
Balanced :2 Co2O3 + 3 C ----> 4 Co + 3CO2
Co2S3also written asCo_2_S_3_sulfide 2- charge trades with the Cobalt 3+ charge
Cobalt has an oxidation number of 3 (III) in the compound Co2O3.
In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
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.
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
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.
Balanced :2 Co2O3 + 3 C ----> 4 Co + 3CO2
TiCO3 is the chemical formula of titanium carbonate.
The appropriate rule is that for each element in the formula unit or molecular formula of a compound, the number of atoms of one element is the product of the subscript following the atomic symbol and the coefficient, a normally sized and placed number preceding the formula unit. If either or both of an explicit subscript or coefficient is missing, the number 1 is assumed. Therefore, 2CO2 contains 4 oxygen atoms and 3 H2O contains 3 oxygen atoms, for a total of 7 in the two formulas combined.
