Magnesium carbonate, Mg CO3 (archaic name magnesia alba), is an inorganic salt that is a white solid.Several hydrated and basic forms of magnesium carbonate also exist as minerals.orms [edit]. The most common magnesium carbonate forms are the anhydrous salt called magnesite (MgCO 3) and the di, tri, and pentahydrates known as barringtonite (MgCO 3 Â·2 H 2 O), nesquehonite (MgCO 3 Â·3 H 2 O), and lansfordite (MgCO 3 Â·5 H 2 O), respectively.
Reaction type: Nucleophilic Substitution (SN1 or SN2). Summary: 1  When treated with HBr or HCl alcohols typically undergo a nucleophilic substitution reaction to generate an alkyl halide and water.eaction of Alcohols with other Halogenating agents (SOCl2, PX3). Reaction type: Nucleophilic Substitution (SN1 or SN2). Summary: 1  Alcohols can also be converted to alkyl chlorides using thionyl chloride, SOCl2, or phosphorous trichloride, PCl3.
Report Abuse. It takes 1 hour for 1 unit of alchohol-BUT only after you stop drinking. 1 Unit of alcohol is The volume in milliltres times the % alcohol by volume divided by 1000.Therefore 1/2 litre (approx 1 pint or 20 fl oz) of Heineken will take 2 hours 30 minutes to leave your body.Heineken is 5% abv (alcohol by volumne) so 5x500/1000=2.5 units. BUT AGaIN STRESSING only after you stop drinking.eport Abuse.
