Can anyone tell me what you'd expect to see with the following? And tell me if mine are right so far? (Observations meaning colour solution, precipitate, gas, solid dissolving, solid/solution changing colour, no reaction):

1)MgCO3 (s) + 2HCl (aq) ---> MgCl2 (aq) + H2O (l) + CO2 (g)
-Bubbling?
-Solid Dissolves?

2)NaOH (aq) + HNO3 (aq) ---> NaNO3 (aq) +H2O (l)

3) K2CO3 (aq) + 2HNO3 (aq) ---> 2KNO3 (aq) + H2O (l) + CO2 (g)
-Bubbling?




4) Cu(NO3)2 (aq)+K2CO3 (s) ---> CuCO3 (s) + 2KNO3 (aq)
-CuCO3 precipitate formed? What colour?

5) Cu(NO3)2 (aq) + Fe(s) ---> Fe(NO3)2 (aq) + Cu (s)

Also are the state symbols right (particularly the highlighted ones)?

Thanks so much!

You wouldn't see anything in (2)

I'm blue/green colour blind, so (4) is hard for me. I think it's a blue/green solid, though.

In (5) the blue-ish copper nitrate will decolourise and copper (which is red/brown/pink/copper coloured/black?) would appear on the surface of the iron.

State symbols look fine to me - the ones on the reactant side we can't know if they're aq, but at least they're all soluble.

Thanks so much! Are all the observations I wrote okay?
