Calcium carbonate makes limestone, while magnesium carbonate makes dolomite.
Limestone.
The chemical name for limestone is calcium carbonate.
It is Calcium Carbonate
limestone
When calcium carbonate reacts with an acid, it produces carbon dioxide gas, water, and a calcium salt. When calcium carbonate reacts with heat, it decomposes into calcium oxide (quicklime) and carbon dioxide gas. Lime stone, which is primarily composed of calcium carbonate, can undergo similar reactions.
You can calculate the value of calcium carbonate in limestone by determining the percentage of calcium carbonate present in the sample and then multiplying that by the market price per ton of calcium carbonate. The formula is: Value = (Percentage of calcium carbonate / 100) x Market price per ton.
Lime Stone(Calcium Carbonate)
Calcium carbonate is deposited from marine or freshwater sources over time, accumulating in layers and eventually forming limestone through compaction and cementation processes. The accumulation of shells, coral, and other biological remains containing calcium carbonate contribute to the formation of limestone.
The word equation for this reaction is: calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxide.
Lime stone is nothing but purely calcium carbonate.
