I believe the following reactions will occur and will result in the following manner:

Magnesium carbonate and dilute sulfuric acid.
MgCO₃(s) + H₂SO₄(aq) --> MgSO₄(aq) + H₂O(l) + CO₂(g)


Nickel sulfate solution and hydrogen sulfide gas.
NiSO₄(aq) + H₂S(g) --> NiS(s) + H₂SO₄(aq)
Mainly because metal sulphides are insoluble


Aluminium chloride solution and aqueous ammonia solution.
AlCl₃(aq) + 3NH₃(aq) + 3H₂O(l) --> Al(OH)3(s) + 3NH₄Cl(aq)
or AlCl₃(aq) + 3NH₃(aq) + 3H₂O(l) --> Al(OH)4(aq) + NH₄Cl(aq)
But I don't know which one would occur and if there will be a precipitate produced.

Lithium chloride solution and potassium nitrate solution.
LiCl(aq) + KNO₃(aq) --> LiNO₃(aq) + KCl(aq)
I am not sure if this would proceed since they are both aqueous, how could you tell the difference?

No suh thing as Al(OH)₄ - if anythng, it has to be charged.

This is tricky. I think result depends on the concentrations.

Good question - perhaps just nothing happens?

Sorry just a formatting error.

Would you be able to point me in the right direction to where to find information on both reactions? I want to learn more about it and especially since you said it is concentration dependent

the fourth reaction, I have a feeling now that the reaction won't occur because I have a feeling they both are highly soluble. Is that consistent in practical application?
