uses of calcium carbonate bone

It is a type of supporting tissue in which matrix is hard and solidified due to the presence of more of inorganic substances. The inorganic salts in the matrix account for nearly 60% of the total chemical composition. Among the inorganic salts, calcium phosphate accounts for about 80% ..

Bone is the hardest connective tissue in the body. It is composed of nearly 50% water and the remaining solid part is composed of a mineral matter, mainly calcium salts and cellular matter. A bone is externally covered by a thick, white dense fibrous sheath called the..

(i) Take calcium chloride in a beaker and dissolve it in water. (ii) In another beaker dissolve sodium carbonate in water. (iii) Add the sodium carbonate solution into calcium chloride solution and stir well. Reaction occurs and a white precipitate is formed..

Similarly, when hydrogen gas and iodine vapours are heated in a closed vessel at a constant temperature, 717K, the two react to form hydrogen iodide. In the beginning, the colour of the reaction mixture is deep violet due to the presence of iodine. But as the reaction proceeds, the intensity of th..

Ammoniacal brine next enters the carbonating tower from the top. This tower is partitioned using horizontal plates that have a central hole and covered with a perforated plate. The ammoniated brine meets the rising stream of carbon dioxide to form crystals of sodium b..

Presence of Carbon Dioxide in Air - Another important constituent of air is carbon dioxide. As stated before, plants use it to synthesize carbohydrates, a basic food for all of us. It is also one of the green house gases that help to retain the warmth of the suns rays ..

This solution removes the vapours of hydrogen chloride from the carbon dioxide gas. The gas is now passed through concentrated sulphuric acid to remove water vapour. It is then collected over mercury. Remember : Dilute sulphuric acid should not be used in this preparation as it ..

1. Carbon monoxide is used as a fuel by itself, or in the form of producer gas (mixture of carbon monoxide and nitrogen), or water gas (mixture of carbon monoxide and hydrogen). It is also present in fuel gases like coal gas. 2. It is used as a redu..

Carbon monoxide is used as a fuel by itself, or in the form of producer gas (mixture of carbon monoxide and nitrogen), or water gas (mixture of carbon monoxide and hydrogen). It is also present in fuel gases like coal ga..

Carbon monoxide is a powerful reducing agent. It is used for the reduction of haematite in the blast furnace. ..
