Answer :
When a 1.00 gram sample of limestone was dissolved in acid, 0.38 gram of co2 was generated. If the rock contained no carbonate other than caco3, 86% percent of CaCO3 by mass in the limestone.
Radon is a gas that is dangerous to breathe in under normal conditions, unlike all the other intermediate elements in the aforementioned decay chains. Exposure of radon gas varies depending on t Limestone, a type of carbonate sedimentary rock made mostly of calcium carbonate, is the main source of the material lime (CaCO3). The majority of its constituents are the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone is produced when these minerals separate from water that has calcium dissolved in it. This can be caused by both biological and nonbiological processes, while biological ones—like the accumulation of corals and shells in the sea—have likely been more important over the previous 540 million years. Limestone makes up the majority of the carbonate rock in sedimentary rock, which comprises 20% to 25% of it. The majority of the remaining carbonate rock, which is closely related to dolomite and contains a significant amount of the mineral dolomite, CaMg(CO3)2, is carbonate rock.
