Answer 1

Draw the structure of H2SO5, CrO5 and NO3 negative. Also mention the oxidation state of each atom

Answer 2

Welcome dear,

[Refer to the image for structures of all 3 compounds.]

● Calculation of oxidation state -
# OS of S in H2SO5 :
Let x be OS of S.
2(+1) + 1(x) + 3(-2) + 2(-1) = 0
x = +6

# OS of Cr in (Cr2O7)2- :
Let x be OS of Cr.
7(-2) + 2(x) = -2
x = +6

# OS of N in (NO3)- :
Let x be OS of N.
1(x) + 3(-2) = -1
x = +5


Hope this helps you...
