Problem
A kidney stone consisting largely of CaCO₃(s) can be dissolved by flushing it with dilute HCl(aq) according to the net ionic equation
CaCO₃(s) + 2 H⁺(aq) → Ca²⁺(aq) + CO₂(g) + H₂O(l)
Which classification best describes this reaction?
(a) Redox reaction involving electron transfer between CaCO3 and H+
(b) Single-displacement reaction in which H+ replaces Ca2+ in the solid
(c) Acid–base reaction that produces a gas as one product
(d) Precipitation reaction forming an insoluble compound
