(aq) is from aqueous, a substance in solution.
HCN(aq) ==> H^+(aq) + CN^-(aq)Ka = [H+][CN-]/[HCN] and the value can be looked up in a book or on line.
Barium chloride and sodium sulfate Molecular equation: BaCl2(aq) + Na2SO4(aq)--> BaSO4(s) + 2NaCl(aq) ionic equation: Ba+2(aq) + 2Cl-(aq) + 2Na+(aq) + SO4-2(aq) --> BaSO4(s) + 2Na+(aq) + 2Cl-(aq) Net ionic equation is Ba+2(aq) + SO4-2(aq) --> BaSO4(s)

Water filters for showers can be purchased on amazon.com, Home Depot or Loews. Amazon offers a water filter that does not require any tools for its installation, however, a pair of pliers are useful. This filter is called Aquasana AQ-4100 Deluxe Shower Water Filter System with Adjustable Showerhead.
Balanced Molecular Equation:HNO2(aq) + NaOH(aq) NaNO2(aq) + H2O(l)Complete Ionic Equation: HNO2 (aq) + Na+ (aq) + OH- (aq)Na+ (aq) + NO2- (aq) + H2O (l)Net Ionic Equation: HNO2 (aq) + OH- (aq)NO2- (aq) + H2O (l)
SO42-(aq) + Ca2+(aq) ---> CaSO4(s)
Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) -> H2O(l) + Na+(aq) + Cl-(aq)
Molecular Eq HC2H3O2(aq) + NH3(aq) -> NH4+(aq) + C2H3O2-(aq) Ionic Eq H+(aq) + C2H3O2-(aq) + NH3(aq) -> NH4+(aq) + C2H3O2-(aq) Net Ionic Eq H+(aq) + NH3(aq) -> NH4+(aq)
Mg(NO3)2(aq) + H2SO4(aq) ==> MgSO4(aq) + 2HNO3(aq) Complete molecular equationTotal ionic equation:Mg^2+(aq) + 2NO3^-(aq) + 2H^+(aq) + SO4^2-(aq) => Mg^2+(aq) + SO4^2-(aq) + 2H^+(aq) + 2NO3^-(aq)RESULT - NO REACTION
NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq) KOH(aq) + HCl(aq) → KCl(aq) + H2O(l) Pb(NO3)2(aq) + KI(aq) → PbI2(s) + KNO3(aq) BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2NaCl(aq) H2SO4(aq) + 2NaOH(aq) → Na2SO4(aq) + 2H2O(l)
The ionic equation for the reaction between magnesium perchlorate (Mg(ClO4)2) and copper(II) chloride (CuCl2) is: Mg(ClO4)2 (aq) + CuCl2 (aq) -> MgCl2 (aq) + Cu(ClO4)2 (s) The net ionic equation is: Mg2+ (aq) + 2ClO4- (aq) + Cu2+ (aq) + 2Cl- (aq) -> Mg2+ (aq) + 2Cl- (aq) + Cu2+ (aq) + 2 ClO4- (s)
