double displacement reaction of weak acid by strong acid.Since,neutralisation means formation of unionised molecule of water,according to Arrhenius'theory.In this reaction,carbonic acid is formed which loses carbon dioxide at room temperature.Here carbonic acid is displaced by hydrochloric acid.Hence,it is displacement reaction.Its equation is,
CaCO3 + 2HCl -------> CaCl2 + H2CO3
but,H2CO3 loses CO2 at room temperature.Therefore it becomes,
CaCO3 + 2HCl ------->Cacl2 + H2O + CO2
Limestone is dissolved by carbonic acid through a process called chemical weathering. Carbonic acid forms when rainwater combines with carbon dioxide in the atmosphere or soil, creating a weak acid that gradually breaks down the calcium carbonate in limestone over time.
Carbonic acid
The weathering process is chemical weathering, specifically dissolution. The acid in the rain reacts with the calcium carbonate in the limestone, causing it to dissolve and wear away over time.

NH3 + HCl --> NH4 + + Cl - Some kind of single displacement ionic reaction. Could also be called an acid base neutralization reaction.
An acid-base reaction that leaves no excess H+ or OH-
Corrosion is the type of reaction between metals and acids.
This is considered an acid/base reaction.
A chemical reaction.
This is a thermal decomposition reaction.
The reaction described is a chemical reaction known as neutralization. In this reaction, an acid (carbonic acid H2CO3) reacts with a base (sodium carbonate Na2CO3) to form a salt (sodium carbonate Na2CO3), water (H2O), and carbon dioxide (CO2).
A waterfall is not a chemical reaction.
