Carbonates | AMERICAN ELEMENTS

Metal carbonates decompose into carbon dioxide and a metal oxide upon heating, a process known as calcination. This name is derived from calx, the Latin name of calcium oxide or quick lime, which is produced by roasting calcium carbonate minerals, known commonly as limestone, in a kiln.

The Reaction Of An Acid With A Metal | Reactions Of …

A possible extension is to hold a cold piece of metal or glass above the place where you burst the bubbles so that the water vapour that forms during the reaction condenses on the metal or glass. Place approximately 1 g of the magnesium pieces in the test tube, but do not add the hydrochloric acid until everything else is ready to be asseled.
