Answer 1

don't know bro

Explanation:

coz it's class 12th question

Answer 2

Explanation:

For given formula of sulphate of metal, its valency is +2

OH is hydroxide ion. By balancing charge, formula of metal hydroxide ion is M(OH) 2

(i) CLO2 is chlorite ion. We need 2 such ions for charge balance. Hence metal chlorite M(CIO2)2.

(ii) Chloride has Cl ion. Hence, metal chloride is MCI2

(iv) NO3 is nitrate ion. By charge balance, metal nitrate is M(NO3)2

(v)NO is nitrite ion. Hence M(NO2)2 is metal nitrite.

(vi) Peroxide has O ion. By charge balance, metal peroxide is MO2

(vii) Cro42- is chromate ion. Hence, by balancing charges metal chromate is M(Cro4).

(viii) (PO4)3- is phosphate ion. By charge balance, metal phosphate is M3(PO4)2.
