molecular equation for the reaction of magnesium metal with aqueous silver nitrate

> magnesium + silver nitrate Mg(s) + 2AgNO, (aq) → Mg(NO3)2(aq) + 2Ag(s) copper(11) nitrate silver Cu(NO3)2(aq) Ag(s) silver nitrate AgNO,(aq) Write the molecular equation for the reaction of magnesium metal with aqueous silver nitrate. Include physical states. molecular equation:

Answer 1

Given magnesium metal = Mg(s), aqueous silver nitrate = AgNO3 (aq), the reaction is Mg(s) + 2AgNO3(aq) + Mg(NO3)2 (aq) + 2Ag(s) This is molecular balance equation. To get net ionic equation, first right the total ionic equation, Write the soluble ionic compounds as dissociated ions, and non-soluble compounds expressed same as it is. Mg(s) + 2Ag+ (aq) + 2NO3(aq) + Mg - (aq) + 2NO3 (aq) + 2Ag (s) Net ionic equation Here we didn't change the representation of products Ag(s) and Mg(s). In the complete ionic equation, we see that NO; is present on both sides of the reaction arrow. Ionic species are not changed in the reaction are called spectator ions. We can cancel out spectator ions from our complete ionic equation since they appear on both sides of the equation. Therefore net ionic equation is Mg(s) + 2Ag+ (aq) + 2NO, faq) + Mg2 (aq) + 2NO, taq) + 2Ag (s) Mg(s) + 2Ag+ (aq) + Mg - (aq) + 2Ag (s) (this is the net ionic equation) Mg(s) + 2Ag+ (aq) + Mg+2 (aq) + 2Ag (s) (this is the net ionic equation)
