1.consider this reaction
2NH₃(aq)+ CO₂(aq)+H₂O(l)--->(NH₄)2CO₃(aq)

As ammonia and carbon dioxide are under an aqueous state, then why "H2O" is shown on this equation?
Does that mean "H2O" is involved in the reaction??

2.consider this reaction
HCl(aq)+NaOH(aq)--->NaCl(aq)+H₂O(l)

The two reactants are under an aqueous environment, so what the significant meaning of the product "H20"? Does this mean that the water level will rise after the reaction? Like, if we start having 2 moles of water molecules in the solution, we will end up of having 3 moles of water molecules?

3. Does the state (aq) mean that compound is soluble in water?? What if that compound is currently soluble in another solvent, say, benzene. what symbol will we use to show it's soluble in that??

Thank you!!

Please read forum rules. You must show your attempt. Won't hurt to obey other points (like Red Violations 2) as well.

Wil" you be able to balance both equations without water?

I attempted doing that..but I just wanna know what it actually means....

i don't the proof from the calculation, but the microscopic view...

No idea what you mean - but balanced equation will give you insight into microscopic situation.

since the first equation you have shown takes place in aqueous solution, water molecules can be added to the equation to maintain the balance of hydrogen and oxygen atoms/ions.
        As for the second equation, it is a neutralisation reaction. it shows that when an acid (HCl) and a base (NaOH) react, salt (NaCl) and water are formed. And yeah, im fairly sure that the water level would rise, so to speak, as new water molecules are being formed and the ones from the start are not changing form.
