Solid chromium (III) hydroxide reacts with nitric acid. Write the balanced net ionic equation.?

Question

Cr(OH)3(s) + 3HNO3(aq) --> Cr(NO3)3(aq) + 3H2O(l)
This is the correct balanced chemical equation.

I have tried entering both:
3OH-(aq) + 3H+(aq) --> 3H2O(l)
3OH-(s) + 3H+(aq) --> 3H2O(l)

But neither are marked correct. Could someone please tell me what is wrong with my answer?

You cannot take a solid apart. The solid has to be together. 
You have to keep the solid and then take out the spectator ions,which would be nitric acid. 

Cr(OH)3 (s)+ 3H+ (aq) --> Cr3+ (aq) +3H2O

(b) Solid chromium (III) hydroxide reacts with nitrous acid. Cr(OH)3 (s) + 3HNO3(aq) → Cr(NO3)3(aq) + 3H20(l) Cr(OH)3(s) + 3H(+)(aq) + 3NO3(-)(aq) → Cr(+3)(aq) + 3NO3(-)(aq) + 3H2O(l) Cr(OH)3(s) + 3 H(+)(aq) → Cr(3+)(aq) + 3H2O(l)
