Magnesium: extraction Brife introduction Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources
Manufacture of calcium oxide (quicklime) It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

Acetylene is a colorless, coustible gas with a distinctive odor. When acetylene is liquefied, compressed, heated, or mixed with air, it becomes highly explosive. Acetylene may be generated by the chemical reaction between calcium carbide and water.
Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable (unlike its sister magnesium) but not fast enough at room temperature to generate much heat. Part of the slowness of the calcium-water reaction results from the metal being partly protected by insoluble white calcium hydroxide .
1. Calcium metal reacts with water to form solid calcium hydroxide and hydrogen gas. Ca + 2H2O → Ca(OH)2 (s) + H 2 (g) 2. Zinc hydroxide solution reacts with lithium to form lithium hydroxide solution and zinc metal. Z(OH)2 (aq) + 2 Li → 2 LiOH (aq 3H

Two thirds of the world’s hydrogen production is devoted to the manufacture of ammonia, which is a fertilizer and used in the manufacture of nitric acid. Large quantities of hydrogen are also important in the process of hydrogenation , discussed in the chapter on organic chemistry.
Position of the non-metal (Hydrogen) in the periodic table and general group characteristics with reference to valency electrons, burning, ion formation applied to the above mentioned element. (i) Hydrogen from: water, dilute acids and alkalis. (a) Hydrogen from•
Reaction of Metal Oxides with Hydrogen The lower position of metal in reactivity series, the easier hydrogen remove oxygen from metal oxide by heating. At higher position, stronger heat is needed. E.g. PbO reacts with H 2 can be reduced by bunsen burner 2 2
Pasteurized milk lost a lot of calcium during processing, and adding a small amount of calcium chloride can help coagulate. Calcium chloride is also an important additive in cheese. Additional food processing appliions include meat tenderization, as a refrigerant in the manufacture of ice cream and frozen foods, reducing oil consumption and darkening of French fries and more.
Many metals react with oxygen gas to form the metal oxide. For example calcium reacts: 2Ca(s) + O2(g)--> 2CaO(s) Calculate the mass of calcium prepared from 4,20g of Ca and 2.80g of O2. (a) How many moles of CaO can form from the given mass of Ca? (b
Hydrogen fluoride is a clear, colorless, fuming liquid or gas with a sharp, pungent odor. Diluted with water, it forms hydrofluoric acid solutions, which are most commonly sold to industry in concentrations of 49% and 70%. Typical physical properties for hydrogen

Calcium Carbonate + Hydrochloric Acid --> Calcium Chloride + Water + Carbon Dioxide. You would see the Calcium Carbonate slowly dissolve and the Carbon Dioxide being made as bubbles. But you would not see the Calcium Chloride or the water being made since there is already water in the flask and the C al cium Chloride will dissolve in it.
Calcium The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.
