Question

Choose the set of equations that best describe the reaction between the sodium carbonate and hydrochloric acid in experiment 1.

Select one:
a.
(1) HCl (g) → H+ (aq) + Cl- (aq)
(2) NaOH (s) → Na+ + OH-


b.
(1) Na2CO3 (s) → 2Na+ (aq) + CO3 2- (aq)
(2) HCl (g) + H2O (l)→ H3O+ (aq) + Cl- (aq)
(3) 2H3O+ (aq) + CO32- (aq) → H2CO3 (aq) +2H2O (l)
(4) H2CO3 (aq) → CO2 (g) + H2O (l)


c.
(1) HCl (g) → H+ (aq) + Cl- (aq)
(2) NaOH (s) → Na+ + OH-
(3) Na+ (aq) + OH- (aq) + H+ (aq) + Cl- (aq) → NaCl (aq) + H2O (aq)


d.
(1) NaHCO3 (aq) → Na+ (aq) + HCO3- (aq)
(2) HCl (g) → H+ (aq) + Cl- (aq)
(3) H+ (aq) + HCO3- (aq) → CO2 (g) + H2O (l)
