Question

The net ionic equation for solid sodium carbonate and aqueous hydrochloric acid is

a) Na₂CO₃(s) + 2 H+(aq) + 2 Cl-(aq) 2 NaCl(s) + H₂O(l) + CO₂(g)
b) Na₂CO₃(s) + 2 H+(aq) + 2 Cl-(aq) 2 NaCl(aq) + H₂O(l) + CO₂(g)
c) 2 Na+(aq) + CO32-(aq) + 2 H+(aq) + 2 Cl-(aq) 2 NaCl(aq) + 2 H₂O(l) + CO₂(g)
d) Na₂CO₃(s) + 2 H+(aq) + 2 Cl-(aq) 2 NaCl(aq) + H₂CO₃(aq)
e) Na₂CO₃(s) + 2 H+(aq) + 2 Na+(aq) + H2O(l) + CO₂(g)

Answer 1

The net ionic equation for the reaction between solid sodium carbonate and aqueous hydrochloric acid is 2 H+ (aq) + CO3^2- (aq) → H2O (l) + CO2 (g).

Step-by-step explanation:

The net ionic equation for the reaction between solid sodium carbonate (Na2CO3) and aqueous hydrochloric acid (HCl) is:

2 H+ (aq) + CO32- (aq) → H2O (l) + CO2 (g)

In this reaction, the sodium and chloride ions are spectator ions and do not participate in the formation of the products. The net ionic equation focuses only on the ions that are involved in the chemical change.
