Write the correct equation for the formation of a white precipitate on mixing together 10 mL each of 1 M calcium chloride, 1 M calcium bromide, 1 M calcium nitrate, 1 M sodium carbonate, 1 M potassium carbonate, and 1 M rubidium carbonate.

Answer 1

The net ionic equation is as follows:
Ca^2+(aq) + CO3^2-(aq) ==> CaCO3(s)

You can use that to write the molecular equations.
