Answer 1

land Net conic equation is obtained from conic equation. lonic equation is obtained from balanced equation, after splitting up only the aqueons reactants and products. Once we have Ronie egration, Common tons on both reactant and Product Scle is lancelled out to get net ionic equation. 1 Brzt2 NaI y 2 Na Br + I2 Bry is liquid (d), NaI is aqueous (Aq), Nabr allo aqueons, Iz is Solid (s). Splitting only Agreens molecules, Brz (1) + 2Nat (ap) + 21 (ap) -> 2Ng Cap) + 2Br (ap) + Iz (8) znat is common on both lides, cancelling it, Brz(1) + 25- Cap) y2Br Cop) + 12 (A), is net conic equation So option c is correct antwel. 2. Clusone (ap) + Calls (ap) y Cuch, lap). Casou (s). Casoy is water intoluble. Zone equation it, cuit (ap) + sou (ap) +6224cap) +240 (aq) y cat lop) + 2 etap) + Casouls) Cancelling out Common teams, Souf (ap) + Cat (ap) y sople) is the net conic equateni option E is antwee 3. Hg (NO3)2 + 2 KOH YHg (OH)₂ +2 KNO3 Hg(NO3)2 (ap) + 2 Koh (ap) -> Hq (04) (S) + 2 KNO (ap). So, tght (ap) + 2003 (ap) +24" (cap) + 204 (ap) -> Hg(OH)2 (s) + 24 (op) + 2NO3(af) Hg 24 (ap) + 2011 Cap) y Hg(OH)₂ (s). is not conic equation Ophon K is anhuel.
