The real reactivity of aluminium | Exhibition chemistry | …
To remove the oxide layer from the metal, put the aluminium sheets in a beaker containing 2 M hydrochloric acid for about a minute - bubbles of hydrogen should be seen as the reaction takes place. Using tongs, remove the aluminium sheets from the acid bath and transfer them to the beaker of mercury.
Calcium is reactive and, for a metal, soft (with difficulty, it can be cut with a knife). In contact with air, calcium develops a mixed oxide and nitride coating, which protects it from further corrosion. Calcium reacts easily with water and acids and the metal burns

Aluminum Carbide You can say it is a by-product of manufacturing calcium carbide. It has an appearance of yellow or brown colour. It reseles crystals which can dissolve in water easily. We use it in cutting tools and also add it to some metals. This will help
Oxidation and Reduction - Purdue University
The reaction between magnesium oxide and carbon at 2000C to form magnesium metal and carbon monoxide is an example of the reduction of magnesium oxide to magnesium metal. After electrons were discovered, chemists became convinced that oxidation-reduction reactions involved the transfer of electrons from one atom to another.
calcium oxide | Infoplease
It is prepared by heating calcium carbonate (e.g., limestone ) in a special lime kiln to about 500 C to 600 C, decomposing it into the oxide and carbon dioxide. Calcium oxide is widely used in industry, e.g., in making porcelain and glass; in purifying sugar; in preparing bleaching powder , calcium carbide, and calcium cyanamide; in water softeners; and in mortars and cements.
Calcium hydroxide | Podcast | Chemistry World
Calcium oxide may have been slaked to produce it, but the hydroxide is still an aggressive base that will burn the skin, damage the eyes and put the lungs at risk if inhaled. In fact, in a controlled way, this ability to burn is the reaction used in most hair removal
