Explain your answer. Question. Think about it: Since hardshelled organisms evolved about 550 million years ago, billions of tons of limestone rock have been produced from their shells. Limestone is made of calcium carbonate, with the formula CaCO3.
#0183;#32;Limestone has a Moh''s hardness of about 3 b/c it is made up of calcium carbonate (calcite). That is really not too hard. Also, depends on the porosity. I have seen some limestone that was pretty easy to break. If it has a lot of fossils in it (esp. shells) amp; has lots of holes. I have a few core samples like this that break relatively easily.
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don''t dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3 ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
Is limestone a hard rock? Quora
#0183;#32;Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an
How hard is limestone on the Mohs scale? Halite has perfect cleavage and a hardness of on the Mohs hardness scale. Limestone is the most abundant of the nonclastic sedimentary rocks. Limestone is produced from the mineral calcite (calcium carbonate) and sediment.
Hard and soft are relative attributes. Compared to a Marshmallow, limestone is very hard. It''s even harder when comparing it with candy floss. In comparison to granite, steel or diamonds
Carboniferous limestone takes form as either a finegrained calcite mud in ancient shallow seas or as shelly limestone. Shelly limestone forms from layers of crushed coral. Both find use in industry as strong stones for use in roads, cement, and architecture. Caches of limestone from different locations can possess different hardness scores.
Hard and soft are relative attributes. Compared to a Marshmallow, limestone is very hard. It''s even harder when comparing it with candy floss.
#0183;#32;Carbonatecemented sandstones therefore contain a hard mineral and a soft mineral. Silicacemented sandstones (quartzites) are uniformly very hard amongst the hardest rocks on earth. 5 0. Chewie. 1 decade ago. real answer pure limestone is calcite, and has a hardness on the Mohs scale of 3. With impurities you are looking at more
#0183;#32;Limestone is made up of calcium carbonate which reacts with acids. Acid rain will cause erosion and depending on your proximity to such places as a coalfired power station, factories, wind, sand, etc., the rate will vary.
Limestone has many other uses. Powdered limestone is used as a filler in paper, paint, rubber, and plastics. Crushed limestone is used as a filter stone in onsite sewage disposal systems. Powdered limestone is also used as a sorbent (a substance that absorbs pollutants) at many coalburning facilities. Limestone is not found everywhere.

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

#0183;#32;I live in Austin, TX and I m looking to plant some trees in my backyard. Problem is I can only dig about 612 inches of soil before I hit limestone. What tools can I use to break the limestone? I ve been chiseling it with a hammer and steel point shovel, but its slow progress. thanks
