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.
-1 for each Cl
+3 for Co
oxidation number of I is -1. oxidation number of F is +1.
Zn has oxidation number +2; S has oxidation number -2
The oxidation number for H is +1, and the oxidation number for O is -1.
Oxidation number of Si is +4.Oxidation number of O is -2.
Carbon atoms oxidation number is +2.Hydrogen's oxidation number is +1.Oxygen's oxidation number is -2.
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.
CoCl3
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.
The correct name for the compound CoCl3 is cobalt III chloride.
