What is the oxidation state of each element in mn(cro4)2?

The The oxidation state of each element in Mn(Cro4)2 is

Oxidation state of  Mn is  +4

Oxidation state of  is -2

Oxidation state of Cr is +6

Explanation :

The oxidation number denotes the number of electrons the atom loses in a chemical compound.

Also, oxidation number is equal to the charge of the ion. In the above compound oxidation state of Cro4 is -2 and there are two ions together. Thus, there oxidation state would be -4.

Mn have the oxidation state of +4. And oxidation charge of oxygen is always -2. In equation Cro4 there are 4 oxygen each having oxidation charge of -2. Making it -8 in total. Cro4 has its oxidation charge of -2. Thus adding up the charges it turns out to be +6 for chromium.    

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
