Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Most limestone is composed of skeletal fragments of marine organisms such as coral, forams and molluscs.
Limestone makes up about 10% of the total volume of all sedimentary rocks. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock.
Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, and as a chemical feedstock for the production of lime.
The first geologist to distinguish limestone from dolomite was Belsazar Hacquet in 1778.
Like most other sedimentary rocks, most limestone is composed of grains. Most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. These organisms secrete shells made of aragonite or calcite, and leave these shells behind when they die.
The Fuse is the eighth album by Pennywise, released on August 9, 2005. The Fuse charted at number 36 in Australia on the ARIA Albums Chart, their third lowest position on the chart among the band's album releases.
Limestone cycle revision video that covers all aspects of the GCSE specification on this topic. The videoscribe includes thermal decomposition of metal carbonates, reactions of metal carbonates with acids, advantages and disadvantages of quarrying, the limestone cycle equations and chemical weathering.
http://www.tngun.com/identifying-limestone/ http://www.amazon.com/Kingfisher-Field-Guide-Minerals-guides/dp/086272693X/Sheschinc-20 I needed some limestone to work some cement experiments trying to replicate both the Portland cement patent, and to make slaked lime for mortar mix. This meant I had to be able to identify limestone. Luckily since limestone is calcium carbonate, ( a base). Simple chemistry ensures that when it makes contact with acid it will fizz (which is CO2 being released) as the acid and the base attempt to counteract each other. If you have a large weathered rock, you may get better results if you smash it into little pieces -- limestone is brittle and crushes well. Then simply drop some strong vinegar or weak muriatic (hydrochloric) acid on the rock. If it fizzles,...
This video helps you to evaluate the positive and negative aspects of quarrying for limestone.

Limestone reaction after the combustion process for 72 hours when put in water. Limestone will melt and become smooth and lime powder during the melting process occurs so that the heating evaporating water until exhausted.

This video was made to document the process that was undertaken to build a limestone wall. While challenging with the correct planning and assistance it is very doable as a DIY Project. This wall was planned to have a flush face with rearward hidden piers to support (viewing from front). There is an expansion joint also to allow for movement due to temperature changes etc. This wall was built in Australia, some of the words or lingo used will certainly be different in other parts of the world. Feel free to ask questions or post comments if you are looking to embark on a project like this.

If you have a request for a revision song, please contact me on my Facebook with a list of facts otherwise I'm afraid I cant help! :) x I recorded this in a rush, tired of revision and exams so please bare with the bum notes... MY DEBUT EP IS OUT NOW! iTunes: https://goo.gl/hUQ20B Amazon: https://goo.gl/ppcTob Spotify: https://goo.gl/mBJvEl I don't know about you lot but i just can't remember the Limestone cycle for my exam in a few days so I wrote a song about it. Hope it helps and good luck with your exams:) YOUTUBE: https://www.youtube.com/user/ChristelleLOfficial1 FACEBOOK: https://www.facebook.com/ChristelleMusic SOUNDCLOUD: https://soundcloud.com/christelle-lamb INSTAGRAM: christellelamb
I experiment with hydrochloric acid (HCL) and sulphuric acid (H2SO4) in dissolving a stone sample. I expect to try this method on a larger scale some time soon. This process is used to free fossils from the rock without using abrasives. I calculate the amount of acid needed to dissolve calcium carbonate-based rocks (CaCO3).

In the previous video we saw the traditional lime kilns of Los Caleros, El Salvador in action. Once the limestone is cooked it is mixed with water and in an amazing chemical reaction right before your eyes the limestone turns to quicklime which is used to make cement.
