Sodium carbonate on reaction with hydrochloric acid in equalmolar concentrations gives sodium chloride and sodiumhydrogencarbonate

What happens when sodium carbonate solution is added to dilutehydrochloric acid?(Write balanced chemical equation only

Sodium hydroxide solution (in water) reacts with hydrochloric acidsolution (in water) to produce sodium chloride solution and water

Using the background theory provided, choose the set of equations that best describe the reaction between the sodium carbonate and hydrochloric acid in experiment 1.Question 2Select one:a.     (1)  Na2CO3 (s) →  2Na+ (aq)  + CO32- (aq)   (2)  HCl (g) → H+ (aq) + Cl- (aq)   (3) 2H+ (aq) + CO32- (aq)  → H2CO3 (aq)   (4)  H2CO3 (aq)  →  CO2 (g)  + H2O (l)   b.   (1)  HCl (g) → H+ (aq) + Cl- (aq)    (2)   NaHCO3 (aq) → Na+ (aq) + HCO3- (aq)   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)  Na2CO3 (s) →  Na+ (aq)  + CO3- (aq)   (2)  HCl (g) → H+ (aq) + Cl- (aq)   (3) H+ (aq) + CO3- (aq)  → HCO3- (aq)

1. In an experiment, 0.933 g of a sample of washing soda (Na2CO3. xH2O) wasdissolved in some distilled water. The solution was treated against 0.258 Mhydrochloric acid. 25.4 cm3 of the acid was required for the completion of thefollowing reaction:Na2CO3 + 2HCl → 2NaCl + H2O + CO2i. From the result, calculate the number of moles of sodium carbonate in thesample of washing soda

Indicate whether each species is a reactant, product or spectator.Dilute hydrochloric acid is added to a solution of sodium carbonate, evolving carbon dioxide.2H+(aq) + 2Cl-(aq) + 2Na+(aq) + CO32-(aq) → CO2(g) + H2O(l) + 2Na+(aq) + 2Cl-(aq)
