The reaction between antacid tablets and hydrochloric acid is classed as an acid-base reaction, and is also called a neutralisation reaction. The base or alkali in the reaction is in the antacid tablet. These reactions produce a salt (not necessarily table salt NaCl) and water.
It is a chemical change. Depending on the antacid, the active ingredient in the tablet (which is a base) will react with the hydrochloric acid to produce water, a salt, and sometimes carbon dioxide.
Chemical.
The Law of Mass Conservation is related to a closed system; but also in this case the initial mass of the antacid tablet is equal to the sum of masses of the products obtained after the reaction.
Chemical reactions can't truly be reversed in any way. Separating the antacid tablet's contents from the water may be possible, but the material won't be a single, whole tablet again, and might not even be a single material at that point.

It is simply acid base neutralization.
It is a chemical change. Depending on the antacid, the active ingredient in the tablet (which is a base) will react with the hydrochloric acid to produce water, a salt, and sometimes carbon dioxide.
The reaction is that the two become neutral water. An H+ (hydrogen atom) bounces off the HCl (hydrochloric acid atom) and attaches itself to the OH- (solid)* in the solid most likely NaOH (solid)*. When H+ is combined with OH- you get H20, or simply water, neutral boring, odorless, $1 a bottle, water.

this chemical reaction forms a gas that may rupture the container or explode.

antacid tablet are chewed because they can act faster whereas swallowed tablet act slowly.
