ANSWER

The formal charge on three oxygen atom has electron pair shared by chlorine,

Cl=

2S−L

v−1

=0=

2×2−6

6−1

=−1

The formal charge on the oxygen atom having an electron pair shared by chlorine and hydrogen, then the formal charge is :

0=

2×2−0

1−1

=0

Formal charge onH is 0=

2×2−0

1−1

=0

For the Co

For the oxygen:

6−4−

×4=0

For the carbon atom:

4−0−

×8=0

For the second oxygen:
