+4
The oxidation number of Co in LiCoO2 is +3. This is because lithium has an oxidation number of +1 and oxygen has an oxidation number of -2, so the overall charge of the compound is zero, making the oxidation number of cobalt +3.
The oxidation number of carbon in CO is +2. This is because the oxidation number of oxygen is typically -2, and there is only one oxygen atom in CO, so the oxidation number of carbon must be +2 to balance the charge.
The oxidation number of Co in CoSO4 is +2. This is because the oxidation number of oxygen is -2 and the overall charge of the sulfate ion (SO4) is -2, so the oxidation number of Co must be +2 to balance the charges.
The oxidation number for Co in CoO is +2. This is because oxygen typically has an oxidation number of -2, so by setting up an equation Co + (-2) = 0, we find that Co is in the +2 oxidation state in CoO.
To determine the oxidation number for Co in CoCl3, we need to consider that the overall charge of CoCl3 is 0 and Cl has an oxidation number of -1. By setting up an equation (x + 3(-1) = 0) where x is the oxidation number for Co, we find that Co has an oxidation number of +3 in CoCl3.
The oxidation number of Co in LiCoO2 is +3. This is because lithium has an oxidation number of +1 and oxygen has an oxidation number of -2, so the overall charge of the compound is zero, making the oxidation number of cobalt +3.

The oxidation number for Co in CoO is +2. This is because oxygen typically has an oxidation number of -2, so by setting up an equation Co + (-2) = 0, we find that Co is in the +2 oxidation state in CoO.
To determine the oxidation number for Co in CoCl3, we need to consider that the overall charge of CoCl3 is 0 and Cl has an oxidation number of -1. By setting up an equation (x + 3(-1) = 0) where x is the oxidation number for Co, we find that Co has an oxidation number of +3 in CoCl3.
The oxidation number is + for C and -2 for O.
In MnCo2, Mn has an oxidation number of +2, and Co has an oxidation number of -1. This is determined by assigning oxidation numbers based on rules for assigning oxidation numbers to each element in the compound.
The oxidation number of cobalt (Co) in cobalt monosulfide (CoS) is +2, and the oxidation number of sulfur (S) is -2. This is because sulfur typically has an oxidation number of -2 in compounds and cobalt typically forms compounds with a +2 oxidation state.
The oxidation number for Co in CoS is +2, a divalent cobalt cation, since the only anion formed from a single sulfur atom has a charge of -2.
CO is a harmful gas.C shows +2 in CO and it shows +4 in CO2.
The oxidation number of sulfur (S) in Co2S3 is -2. This is because oxygen (O) usually has an oxidation number of -2 and cobalt (Co) has an oxidation number of +2, so the overall charge of the compound must be neutral, making sulfur's oxidation number -2.
To calculate the oxidation number of Co(NH3)6, first identify the oxidation number of ammonia (NH3), which is -3. Since there are six ammonia molecules surrounding the cobalt (Co) atom, the total charge contributed by the ammonia ligands is -3 x 6 = -18. Since the overall charge of the complex is usually 0, the oxidation state of cobalt (Co) in this complex is +3 to balance the charge.
