Cl has an oxidation number of -1 because it is in the group 7a.
-1*6 = -6
K has an oxidation number of +1 and there are three of them.
-6+3+x = 0
The oxidation number of Co is +3.
The oxidation number for the compound MO can vary depending on M. In general, oxygen has an oxidation number of -2. Therefore, you would need to know what element M represents in order to determine the oxidation number for MO.
If an element gains electrons, it has a negative oxidation number. The oxidation number is determined based on the number of electrons gained or lost by an atom in a compound. The rule is that in ionic compounds, the oxidation number of an element is equal to the charge it would have if it were an ion.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
I don't know if this is what you mean but, you know phosphorus will have an oxidation number of -3 because it has 5 valance electrons. For phosphorus to become stable it needs to gain 3 electrons. This adds 3 negative charges to it and gives it the -3 charge.
You can use an online tool to calculate the molar mass of CoCl3 - convertunits.com/molarmass/CoCl3
because if you know the oxidation numbers of all the reactants and products in a given reaction, you can determine which, if any, of the reactants were oxidized and which were reduced. oxidized is when the oxidation number increases, reduced is when the oxidation number decreases.

It is not possible to know the oxidation number in an formula with more then 2 unknowns such as OCN- you only know O is -2.
As written 'cocl3' it means nothing. !!! Do you mean 'CoCl3' or ' COCl3' both of which are different formulae. CoCl3 is 'Cobalt(III) Chloride' COCl3 as a molecule does NOT exist. NB When writing chemical formulae symbols. single letter symbols are ALWAYS a CAPITAL letter. Two letter symbols are written , first letter is a capital letter and the second letter is small/lower case. Hence 'co' is written as 'Co' (Cobalt). 'cl' is written as 'Cl' (Chlorine). Compare to 'C' Carbon and 'O' oxygen . NNB The molecule 'COCl3 ' does not exist . However, there is COCl2, which is 'di-chloro methone' Structurally 'Cl-C(=O)-Cl'.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
