Explanation:

Each chlorine atoms are connected with four oxygen atoms. ... Hence the oxidation state of Cl is +7 and hence the valency of both Cl is 7 only.

Answer 2

2 .x + 7. ( -2 ) = ( - 2 )

2 . x - 14 = -2

Add 14 both sides

2 . x - 14  + 14 = -2 + 14

2 . x = 12

divide both sides by 2

2x / 2 = 12 / 2

x = 6

hence, + 6 is answer
