Ba H O (1) ► 1 Ba(OH)2 ) 128 to NaC2H302 (aq) + H2SO4 (aq) Na2SO4 (aq) + 2_HC2H3020) (e) 2 AgNO3 (aq) + BaCl(aq) AgCl (8) + Ba(NO3)2 (aq) | NiBr2 (aq) + H2(g) (d) Ni (s) + 2HBr (aq) → Fe 03 (5) ► 2 FeCl3 (aq) + 3 H20 (1) (e) HCI (aq) +

Answer 1

Molecular equation is 1 Ba (s) + 2 H20 (1) ---------> Ba(OH)2 (s) + H2 (g) Totalionic equation is 1 Ba (s) + 2 H2O (1) ---------> Ba(OH)2 (s) + H2 (g) Net ionic equation is (discard the counter ions) 1 Ba (s) + 2 H20 (1) ---------> Ba(OH)2 (s) + H2 (g) Molecular equation is NaC2H302 (aq) + H2SO4 (aq) ---------> Na2SO4 (aq) + 2 HC2H302 (1) Totalionic equation is 2 Na+ (aq) + 2 C2H30,- (aq) + 2 H+ (aq) + 50,-2 (aq) ----> 2 Na+ (aq) + 50,-2 (aq) + 2 HC2H302 (1) Net ionic equation is (discard the counter ions) 2 C2H302 (aq) + 2 H+ (aq) ----> 2 HC2H302 (1)

Molecular equation is 2 AgNO3 (aq) + BaCl2 (aq) ---------> 2 AgCl (s) + Ba(NO3)2 (aq) Total ionic equation is 2 Ag+ (aq) + 2NO3- (aq) +Ba+2 (aq) + 2 Cl- (aq) ----> 2 AgCl (s) + Ba+2 (aq) + 2NO3- (aq) Net ionic equation is (discard the counter ions) 2 Ag+ (aq) + 2 C1- (aq) ----> 2 AgCl (s) Ag+ (aq) + C1- (aq) ----> AgCl (s) Molecularequation is Ni (s) + 2 HBr (aq) ---------> NiBrą (aq) + H2 (g) Total ionic equation is Ni (s) + 2 H+ (aq) + 2 Br (aq) ----> Ni+2 (aq) + 2 Br (aq) + H, (g) Net ionic equation is (discard the counter ions) Ni (s) + + 2 H+ (aq) ----> Ni+2 (aq) + H2 (g)

Molecular equation is 6 HCl (aq) + 1 Fe2O3 (aq) ---------> 2 FeCl3 (aq) + 3 H20 (1) Totalionicequation is 6 H+ (aq) + 6 C- (aq) + 1 Fe, 02 (aq) ----> 2 Fe+3 (aq) + 6 Cl- (aq) + 3 H2O (1) Net ionic equation is (discard the counter ions) 6 H+ (aq) + 1 Fe2O3 (aq) ----> 2 Fe+3 (aq) + 3 H20 (1)
