Answer 1

a) balanced molecular equation CH3COOH(aq) + KOH (aq) - CH3COOK(aq) + H2O(1) This reaction is a neutralisation reaction. b) lonic equation: CH3COO (aq) + H+ (aq) + K+ (aq) +OH(aq) CH3C00 (aq) +K+ (aq) +H20() all compounds with (s), (), or (9) unchanged the reaction given above, the complete ionic equation is: CH3C00"(aq) + H*(aq) + K+ (aq) +OH(aq) — CH3CO'"(aq) +K(aq) +H20(1) c) Net ionic equation : remove the common ion, the resulting equation is the net ionic eqaution H*(aq)+ OH(aq) — H2O(1) 2) balanced molecular equation H2CO3(aq) + 2 NaOH(aq) - Na2CO3(aq) + 2 H20 (1) This reaction is a neutralisation reaction. b) lonic equation: 2H*(aq) + CO3 (aq) +2Na+(aq) +2 OH(aq) —_ 2 Nat(aq) +CO3 2(aq) +2 H20 (1) all compounds with (s), (), or (g) unchanged the reaction given above, the complete ionic equation is: 2H*(aq) + Coz?(aq) +2Na+ (aq) +2 OH"(aq) + 2 Na (aq) +CỘ32(aq) +2 H20 (1) c) Net ionic equation : remove the common ion, the resulting equation is the net ionic eqaution 2H+ (aq) + 2 OH(aq) - 2 H20 (1)

a) balanced molecular equation 2HNO3 + Ba(OH)2 Ba(NO3)2 + 2H2O This reaction is a neutralisation reaction. b) lonic equation : 2HNO3(aq) + Ba(OH)2(s) Ba(NO3)2(aq)+ 2H2O(1) 2H+ + 2NO3 + Ba(OH)2(s) + Ba 2+ + 2NO3 + 2H2O(I) all compounds with (s), (), or (g) unchanged the reaction given above, the complete ionic equation is: c) Net ionic equation : remove the common ion, the resulting equation is the net ionic eqaution 2H+ + Ba(OH)2(s) Ba2+ + 2H2O(0)
