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 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.
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 Co in CoF6^2- is +3. This is because each fluorine atom has an oxidation number of -1, and the overall charge of the complex ion is -2. Therefore, the oxidation number of cobalt (Co) must be +3 in order to balance the charges.
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 of Co in CoS is +2. This is because sulfur typically has an oxidation number of -2 in compounds and the overall charge of the compound is neutral.
The oxidation number of C in 3CO is +2, as in carbon monoxide each oxygen has an oxidation number of -2. In 3CO2, the oxidation number of C is +4.
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.
