Limestone is calcium carbonate. If you have a spill of calcium carbonate on the surface try brushing or polishing the floor.
No, it puts carbon into the atmosphere.
Flowers, trees and all growing vegetation remove carbon dioxide from the air using photosynthesis.
The lime (CaO) reacts with SO2: 2CaO (s) + 2SO2 (g) + O2(g) .........> 2 CaSO4 (s) So the sulphur dioxide is removed and deposited as calcium sulphate.
The limestone decomposes to quicklime and carbon dioxide, and the quicklime removes acidic impurities (eg SiO2). So basically limestone is to remove impurities
It can remove them.
Limestone is used as a building material and in chemical industry.
To remove impurities
You can remove mold on limestone basement walls by using mold remover. Bathroom cleaners and bleach also work well for this use.
Plants remove Carbon Dioxide from the environment.
Limestone
do autotrophs remove carbon dioxide from the air
Only by photosynthesis. Plants remove the Co2 for photosynthesis.

Iron ore or Haematite (Fe3O2), Carbon in the form of 'Coke', and Limestone (Calcium Carbonate 'CaCO3') are all used in the blast furnace. Iron Ore is melted down with coke, the coke burns heat into the furnace. Oxygen gas is blasted in from the sides. The carbon (C) and oxygen (O2) react to form carbon dioxide gas (CO2). At higher temperatures more carbon (C) is reacted with the carbon dioxide(CO2) to create carbon monoxide (2CO). The carbon monoxide 'steals' the oxygen from the iron oxide (Fe3O2), reducing the iron oxide to iron. Due to the impurities in the iron, it is called 'pig iron'. Limestone (CaCO3) is added to remove the impurities from the iron. The limestone (CaCO3) reacts with mainly silicate in the iron, and becomes calcium silicate (CaSiO3) and carbon dioxide (CO2). Calcium silicate is known as 'slag' and is used for construction.
Plants remove carbon dioxide during photosynthesis!
