Write a net ionic equation for the reaction that occurs when cobalt(II) carbonate (s) and excess hydroiodic acid are combined.

Answer 1

molecular equation:
CoCO3 + 2HI==> CoI2 + CO2 + H2O

Turn this into an ionic equation.
CoCO3(s)+ 2H^+ + 2I^- ==> Co^2+ + 2I^- + CO2 + H2O

Net ionic equation:
Cancel those ions that appear on both sides of the equation. What's left is the net ionic equation.

Answer 2

Write a net ionic equation for the reaction that occurs when aqueous solutions of sodium hydroxide and hydrochloric acid are combined.

Answer 3

Co(OH)2(s)+2H+---> Co2+(aq)+2h2o(l)

Answer 4

2H^+(aq)+CoCO3(s)—> Co^2+(aq)+H2O(l)+CO2(g)
