No. Limestone is a carbonate rock, no matter how it formed. The formula is always CaCO3.
Yes, limestone from areas where shelled sea creatures are highly abundant typically contains more carbonate. Shelled sea creatures like mollusks and corals have shells made primarily of calcium carbonate. Over time, as their shells accumulate and get compacted, they form limestone. As a result, limestone from these areas will have a higher carbonate content compared to limestone from areas without such abundant sea creatures.
In paints, limestone is used as a filter extending expensive pigments. Limestone is calcium carbonate with the chemical formula of CaCO3.
Limestone and marble (calcium carbonate) dissolve when in cntact with acid rain. Other building matrails like granite are not impacted by acid
Carbon.
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
Chemical formula of magnesium carbonate is MgCO3. Magnesium carbonate contain magnesium, carbon and oxygen.
Yes!
The molecule of limestone (calcium carbonate, CaCO3) contain 5 atoms.
Lime stone is nothing but purely calcium carbonate.
It is not a problem to most people.
In paints, limestone is used as a filter extending expensive pigments. Limestone is calcium carbonate with the chemical formula of CaCO3.
Limestone commonly predominantly contains Calcite and Aragonite which are the two crystal forms of Calcium Carbonate (CaCO3). It commonly also contains detrital clasts (broken pieces of other material) such as flint or chert which are silica. Some limestones also contain the mineral dolomite which is Calcium Magnesium Carbonate (CaMg(CO3))2.
Most carbonate minerals are either calcium carbonate (limestone) or a mixture of calcium carbonate with magnesium carbonate (dolomite). However other metals can also combine with carbonate to produce much rarer carbonate minerals.
No. Sandstone is mostly made of silica whereas limestone is made from calcium carbonate (which may contain some magnesium and other carbonates.

The majority of limestone is made of the calcium carbonate (CaCO3) minerals calcite and aragonite. There are also commonly sand and silt sized clasts of other minerals (e.g. quartz) bound up in the matrix of limestone. Limestone may also contain the mineral dolomite which is a magnesium carbonate (CaMg(CO3)2)
Carbon.
In pure form, limestone is calcium carbonate, and does not contain silica. However, in SOME strata of limestone, silica can be present as an impurity.
