In the balanced net ionic equation for the reaction of solid CaCO₃ and aqueous hydrochloric acid,which produces aqueous chloride and an acid that decomposes into the other two products,what appears on the left side of the net ionic equation?

Question

Quizplus · Accepted Answer

The balanced net ionic equation for the reaction between CaCO3 and HCl is:
CaCO3(s) + 2 H+(aq) → Ca2+(aq) + CO2(g) + H2O(l)
The solid CaCO3 is the only substance that appears on the left side of the equation, and it is also the only solid given in the answer choices. Therefore, only choice D, CaCO3(s) + 2 H+(aq), is a possible answer.
