Answer 1

a) balanced molecular equation Na2CO3(aq) + 2 HCl(aq) - 2 NaCl (aq) + H20 (1) + CO2(g) This reaction is a neutralisation reaction b) lonic equation : all compounds with (s), (), or (9) unchanged the reaction given above, the complete ionic equation is: 29fa(aq) + coz?(aq) +2 H(aq) +2 ¢r(aq) —>2 1șa(aq) + 2 ct (aq) + H2O () + CO2(9) c) Net ionic equation : remove the common ion, the resulting equation is the net ionic egaution co3?(aq) +2 H*(aq) — H20 (1) + CO2(g) KBr(aq) + AgNO3(aq) — AgBr(s) + KNO3(aq) b) lonic equation: all compounds with (s), (), or (g) unchanged the reaction given above, the complete ionic equation is: K*(ab) + Br(aq) + Ag*(aq) + nos (aq) — — AgBr(s) + K+(aq) + Nos (aq) Any dissolved ions that appear in the same form on both sides are spectator ions. Spectator ions are K+ and NO3- Correct option is "c"
