Write a balanced chemical equation for the reaction between solutions of cobalt(III) sulfate and sodium hydroxide.

Also: sodium carbonate and calcium chloride.

I need to know the physical states as well. I tried to do this with ammonium sulfide and nickel(II) bromide and ended up using all my chances on the online course and never got it right.

I am really just lost and can't risk getting any more questions wrong. Please help me. Thank you!

Co2(SO4)3 + 6 NaOH = 3 Na2SO4 + Co2(OH)6

Na2CO3 + CaCl2 = CaCO3 + 2 NaCl

(NH4)2S + NiBr2 = NiS + 2 NH4Br

I can't help you with the states, it's kind of hard to determine.
