They are all dissolved in water.
1)Write the BALANCED equation for the reaction with CORRECT state symbols: Mg(s) +2HCl(aq)---------->MgCl2(aq) +H2(g) 2)Now rewrite the equation replacing aqueous substances as they would appear in solution( ie)as ions.Leave everything else as is in the standard state. Mg(s) + 2H+ (aq) + 2Cl-(aq)---->Mg2+(aq) +2Cl-(aq) +H2(g) 3)Now cancel ions common to both sides ,that is,spectator ions. Cancel the 2Cl-(aq) on each side. 4)Rewrite the equation without what you have canceled. Mg(s) + 2H+(aq)------>Mg2+(aq) + H2(g). Good Luck.
Carbonic Acid
When KOH (potassium hydroxide) aqueous neutralizes HCl (hydrochloric acid) aqueous, potassium chloride (KCl) and water (H2O) are produced. This reaction is a neutralization reaction where the acid and base react to form a salt and water.
Examples of strong alkalis include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These substances are highly reactive and can cause severe burns on skin and tissue.
The gas given off from the reaction between AgNO3 and HCl is nitrogen dioxide (NO2).
These substances are in solution.
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
(aq) is from aqueous, a substance in solution.

In solution, CuC2H3O2 would dissociate into Cu2+ and C2H3O2- ions. The phases involved would be solid CuC2H3O2 dissociating into aqueous Cu2+ and C2H3O2- ions.

Ionisation in solution is not a chemical reaction. It can be written as one but still it's NOT: only physical change of state ( subscripted between brackets (s) or (aq) ) Na2S(s) --> 2Na+(aq) + S2-(aq)
NaNO3(aq) + KCl(aq) ---> NaCl(aq) + KNO3(aq) Na+(aq) + NO3-(aq) + K+(aq) + Cl-(aq) ----> Na+(aq) + Cl-(aq) + K+(aq) + NO3-(aq) NO NIE since they are all spectator ions it is soluble in water and no precipitate forms, there is no net ionic equation
