    durable and long lasting chalk. Until they found out that seashells is made up of calcium carbonate that can also be found in chalk. The term seashells usually refer to the exoskeleton of invertebrate animals. Most seashells are commonly found at the beaches but in a variety of habitats it is also possible to find shells from freshwater animals. But what was known in these animals they are made up of calcium carbonate. It will now be easy for the less fortunate country or people

    eggshell experiment

    Introduction The major component of eggshells is calcium carbonate (CaCO3). Calcium carbonate cannot be dissolved in water‚ but can dissolve in an acid using the reaction: 2HCl(aq)+CaCO3(s) Ca2+(aq)+CO2(g)+H2O+2HCl-(aq) This reaction is not used to titrate the CaCO3 because it is very slow when the reaction is close to the endpoint. Instead adding an excess of acid to dissolve all of the CaCO3 and then titrating the remaining H3O+ with NaOH solution can achieve the determination of the amount

    these kinds of water for a long time‚ calcium hydroxide in the cement paste dissolves first (per liter water can dissolve calcium hydroxide of 1.3g). Under the role of still water or zero-pressure water‚ the dissolution will stop because the surrounding water is easy to get saturated due to the dissolved calcium hydroxide‚ and dissolution only occur on the surface‚ little impact. But if the cement paste is in fluid water or pressure water‚ the dissolved calcium hydroxide is easy to be washed away‚

    is really gypsum (calcium sulfate)‚ but often people call it "chalk". People use it for drawing on hard things‚ because it is soft. If this chalk is rubbed on something hard or rough‚ it will leave a mark. People often write with chalk on a chalkboard or blackboard. A chalk eraser or water can be used to clean the chalk marks away so the board is blankagain. Shops usually sell blackboard chalk in sticks that are about 5 cm long. The main component of chalk is calcium carbonate (CaCO 3 )‚ a form

Mining Carbonate deposits can be done with the following chemical reaction which illustrates a small scale gas extraction procedure: CaCO3(s) + 2HCl(aq) CaCl2(aq) + CO2(g) + H2O(l) Hydrochloric acid would need to be imported from Earth to supply the activities on Mars which acid is reacted with the rocks to generate CO2.

Eggshells The calcium carbonate is the one that gives egg shell its hardy strength - a common substance found in rocks. The team found that calcium carbonate made up almost 98 per cent of an egg shell. The remaining two per cent comprises proteins which act as the "cement" to hold the calcium carbonate together.

    The poem harmonium examines the relationship of a father and son. I think Armitage has written this poem for parents and children as they would be able to relate to the emotions in the poem. The Author uses the Farrand Chappelette which is a type of Harmonium or small organ to help him reflect the love that he has for his father. In the first stanza the poet talks about the Farrand Chappelette which was “gathering dust” telling us that it is getting old and it was due to be taken to the skip if Armitage
