Step 4, add the state symbol…
How do you know what state each are in???
Like which one is the solid?

Hi, I am still confused on how to figure out which parts of the original equation will break up and which to keep together. Can you help please

hey,what about those type of equations that have only one aqueous compound? like H2SO4 + CaCO3 = CaSO4 + H2O + CO2, whereby only sulfuric acid is in aqueous state here, calcium carbonate and calcium sulfate both is solid

Spectator Ion is in AQUEOUS STATE. Check out the example above and see how we determine the Spectator Ion(s).

Hope this helps. Think about it.
