Problem

The balanced net ionic equation for the reaction of hydrochloric acid with aqueous carbonate is 2 H⁺(aq) + CO₃²⁻(aq) → CO₂(g) + H₂O(l) Which statement about the stoichiometric relationship expressed by this equation is correct when performing quantitative calculations? (a) Exactly 1.0 mol1.0\ \text{mol} of H+\mathrm{H^+} is required to completely react with 1.0 mol1.0\ \text{mol} of CO32−\mathrm{CO_3^{2-}}. (b) Exactly 1.0 mol1.0\ \text{mol} of CO32−\mathrm{CO_3^{2-}} yields 2.0 mol2.0\ \text{mol} of CO2\mathrm{CO_2}. (c) Exactly 2.0 mol2.0\ \text{mol} of H+\mathrm{H^+} are required to completely react with 1.0 mol1.0\ \text{mol} of CO32−\mathrm{CO_3^{2-}}. (d) Exactly 2.0 mol2.0\ \text{mol} of H+\mathrm{H^+} produce 2.0 mol2.0\ \text{mol} of H2O\mathrm{H_2O}.
