Question

Write the net ionic equation for:
2NaF + Ca(NO3)2 -> CaF2 + 2Na(NO3)

Answer 1

I wrote NaF -> F- + Na-
not feeling too confident with my answer though...

Answer 2

do you know the states for the compounds. also, chem rule of thumb, Na is always soluble. it's a spectator ion.No3 is also soluble, so it's a spectator ion too.

Answer 3

Na No3 is soluble...it's aqueous, thus, the equation will be Ca +F => CaF2.
Balance it out

Answer 4

Thanks for pointing out solubility of Ca, totally skipped that. Now I'm getting
(2F-) + (Ca 2+) -> CaF2
