This is a faster reaction then the original reaction. The final reaction has the same amount of particles of acid and the magnesium, but the magnesium has been cut to increase the surface area. This makes the acid particles more likely to have more successful collisions each second than the original reaction.

Carbonate - Wikipedia

Chemical properties Metal carbonates generally decompose on heating, liberating carbon dioxide from the long term carbon cycle to the short term carbon cycle and leaving behind an oxide of the metal. This process is called calcination, after calx, the Latin name of quicklime or calcium oxide, CaO, which is obtained by roasting limestone in a lime kiln.

In general, the metal is added to the acid until there is no further reaction. (when no more bubbles of hydrogen gas are produced) Excess metal is then filtered out, and the clear filtrate is then evaporated until crystals form.

Reactivity Series of Metals - Get the Chart, Significance …

In the reactivity series, as we move from bottom to top, the reactivity of metals increases. Metals present at the top of the series can lose electrons more readily to form positive ions and corrode or tarnish more readily. They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent.
