Metal: Reaction with hydrochloric acid: Order of reactivity: Products: Magnesium Vigorously reacts with a stream of gas evolving. 1 st - most reactive. Magnesium chloride, MgCl 2 and hydrogen gas. Zinc Quite slow reaction with a steady stream of gas evolving. 2 nd.
Calcium - DrugFuture
Found naturally only in the form of its compds, never uncoined, in minerals such as limestone, dolomite, marble, chalk, iceland spar, gypsum, anhydrite, fluorite, apatite. Principal commercial source is limestone, q.v. Major commercial production by high temperature vacuum reduction of calcium oxide in aluminothermal process; less commonly by electrolysis followed by redistillation.
Barium - Simple English Wikipedia, the free encyclopedia
As a metal Barium is used to remove oxygen from hode ray tubes and vacuum tubes. It is placed inside and reacts with all of the oxygen, using it up. Barium is also used in spark plug wire. As chemical compounds Certain compounds of barium, such as
Magnesium | Podcast | Chemistry World
Many minerals are known which contain magnesium; but the main ones are dolomite (calcium magnesium carbonate, CaMg(CO 3) 2) and magnesite which are mined to the extent of 10 million tonnes per year. Magnesite is heated to convert it to magnesia (MgO), and this has several appliions: fertilizers; tle feed supplement; a bulking agent in plastics; and for heat-resistant bricks for
Uses of Magnesium - Want to Know it
Uses of Magnesium Magnesium is widely used as a part of aluminum alloys. This includes alloys used in aluminum beverage cans. Magnesium, alloyed with zinc, is used in die casting. In this process the molten metal is forced into a mold (die) under high
CHAPTER3 Metals and Non-metals
basic behaviour . Such metal oxides which r eact with both acids as well as bases to produce salts and water are known as amphoteric oxides. Aluminium oxide reacts in the following manner with acids and bases – Al 2 O 3 + 6HCl → 2AlCl 3 + 3H 2 O Al 2 O 3
Calcium (Ca) and water - Lenntech
Calcium occurs in water naturally. Seawater contains approximately 400 ppm calcium. One of the main reasons for the abundance of calcium in water is its natural occurrence in the earth''s crust. Calcium is also a constituent of coral. Rivers generally contain 1-2

Metal-Water Reactions Chemistry Tutorial
Why would you not use a metal such as magnesium to make water pipes? Response: Magnesium is a more active metal than copper. Magnesuim would react with the water in the pipes to produce magnesium hydroxide which would produce "hard water" (soap won''t lather properly in hard water), causing the magnesium pipe to disintegrate over time.
