No
A compound called calcium hydrogencarbonate is the main cause of hard water. It forms when rain falls on limestone and chalk rocks. These rocks are made of calcium carbonate, which is insoluble in water. Because rain water contains carbon dioxide, dissolved from the air, this makes it acidic. The rain water reacts with the rocks to form calcium hydrogencarbonate which is soluble. This is the white solid that ends up in our kettles. An equation for the reaction is: water + carbon dioxide + calcium carbonate = calcium hydrogencarbonate H2O (l) + CO2 (g) + CaCO3 (s) = Ca(HCO3)2 (aq)
The common name of Calcium carbonate may be Chalk, but chemically that's not true, if it is the blackboard writing chalk. This chalk is actually Calcium sulfate, which is mistaken as Calcium carbonate, as its manufacturing process uses Calcium carbonate.So, I think the common name for chalk should be Limestone, which is the most common mineral form of this compound.
Calcium carbonate is a major component of sedimentary rocks such as limestone, chalk, and marble. These rocks form from the accumulation of marine organisms' shells, coral reefs, and precipitated calcite minerals.
No. Mainly rocks with a high content of iron. Rocks such as silica or calcium carbonate are not.

You think probable to limestone.
That is the correct spelling of the word "limestone" (calcium carbonate rocks).

Calcium acetate is reasonably soluble in water, so vinegar will dissolve limestone (calcium carbonate).
Lime stone is nothing but purely calcium carbonate.
The name of the chemical formula CaCO3 is calcium carbonate. Calcium carbonate is commonly found in rocks and is created when ions in hard water react with carbonate ions to create limescale. The hardness of water is measures in ppm CaCO3.
Calcium carbonate (CaCO3) easily react with acids.
No
No. Calcium carbonate is found in sedimentary and metamorphic rocks. Igneous rocks such as andesite are composed almost entirely of silicates.
