MagnesiteWikipedia
Magnesite can also be formed via the carbonation of magnesium serpentine (lizardite) via the following reaction 2 Mg 3 Si 2 O 5 (OH) 4 3 CO 2 → Mg 3 Si 4 O 10 (OH) 2 3 MgCO 3 3 H 2 O. However when performing this reaction in the laboratory the trihydrated form of magnesium carbonate (nesquehonite) will form at room temperature.

Magnesium oxide MgOPubChem
Magnesium Oxide is the oxide salt of magnesium with antacid laxative and vascular smooth muscle relaxant activities. Magnesium combines with water to form magnesium hydroxide which reacts chemically to neutralize or buffer existing quantities of stomach acid stomach-content and intra-esophageal pH rise resulting in a decrease in pepsin activity. This agent s laxative effect is the result
