Solution

Solution Steps

Step 1: Identify the Reactants and Products

The given reaction is: \[ \mathrm{MgCO}_{3}(\mathrm{~s})+2 \mathrm{HCl}(\mathrm{aq}) \rightarrow \mathrm{MgCl}_{2}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\ell)+\mathrm{CO}_{2}(\mathrm{~g}) \]

Step 2: Determine the Type of Reaction

Precipitation Reaction: This involves the formation of an insoluble solid (precipitate) from two aqueous solutions. In this reaction, no solid precipitate is formed.
Acid-Base Reaction: This involves the reaction between an acid and a base to produce water and a salt. Here, $\mathrm{HCl}$ (acid) reacts with $\mathrm{MgCO}_{3}$, but the products include $\mathrm{CO}_{2}$ gas, which is not typical for a simple acid-base reaction.
Gas-Forming Reaction: This involves the formation of a gas as one of the products. In this reaction, $\mathrm{CO}_{2}$ gas is produced.
