Question

Oxidation number of CaoCl2
​

Answer 1

Answer:

cao cl 2 it is called oxidation adding oxygen

Answer 2

Answer: THE OXIDATION NUUMBER OF Ca in CaoCl2 is +4

Explanation: Let us assume the oxidation number as X and charge=0,since we know the oxidation numbers of oxygen[i.e.=-2] and that of chlorine[i.e.=-1] so let us calculate the oxidation number for calcium

Therefore

X+(-2)+(2*-1)=0

X-2-2=0

i.e. X-4=0

Therefore the oxidation state of Calcium in CaoCl2 is +4.
