Aluminium is a chemical element which is a metal, it is lustrous, ductile and non magnetic. Aluminium is also the third most abundant element on earth and the most abundant element
Magnesium Oxide and Determination of its Empirical Formula Background When elements react to form compounds they do so in specific ratios. The formula that describes the smallest whole number ratio for elements in a compound is the empirical formula. In this experiment, you will heat magnesium in air (a source of oxygen) to generate magnesium oxide. By analyzing the mass of the magnesium and oxygen that have reacted, you will determine the number of moles of each present in the magnesium oxide product

element has three energy levels. The first has 2, the second has 8 and the third has 3. Compounds formed by the Element A very important compound is dialuminum oxide Al2O3. The structure of dialuminum oxide is sometimes hexagonal. The structure is .It is one of the hardest substances known. It is formed by natural occurrence. Dialuminum oxide is formed from the reaction of metallic aluminum with oxygen gas. It is a white crystalline solid. Aluminum chloride has a formula of ALCl3. The structure is
higher level, meaning that technology had to evolve before iron could be smelted and used. Once the iron smelting process was form it rapidly replaced the role of bronze in many civilisations as it was more durable and harder than bronze. 3.

Indium can also be used in the coating of mirrors as it creates the same quality mirrors as silver but
represents the elemental analysis of Orange peel powder and carbon made from Orange peel powder respectively. Besides that this component is widely used to be manufactured as an adsorbent to adsorb (CO2) gas. Orange peel contain Potassium Oxide (K2O) with 1.72%, Calcium Oxide (CaO) with 1.31% and others components in the minority. Therefore, with the great amount of carbon component, carbon produced from orange peel and also orange peel itself is one of the potential adsorbent to adsorb CO2 from gas mixture
are still used in that "completely wooden table" as the screws used to hold it together are made of metals. Many commonly used metals such as iron, aluminium, and/or copper are all found from ores. An ore is a mixture in the form of a rock that is mined. For example, bauxite is an ore that contains a high percentage of pure aluminium. That pure aluminium is then extracted, refined, and crafted in to many everyday items such as cars, foil, and ladders. Chemists are continuously researching an innovative
decided to sell two thirds of Rio Tinto based in Spain so that they can pump money into new developments in other countries. Extensive bauxite deposit was discovered at wepra far north Queensland Australia, that discovery led to Rio Tinto’s entry into aluminium and formation of Comalco limited that was in the year 1956. Six years later Conzinc Rio Tinto Australia was formed, in the year 1966 the first exports to Japan, in Western Australia Rio Tinto launched it’s iron ore operations with the launch of Hamersley
Aluminium Introduction: The element Aluminium has a symbol of Al and has an atomic number of 13. It is a very light, soft and useful metal used for many things such as cans, foil and kitchen utensils. It is a ductile metal, a good conductor of heat and electricity, does not corrode and is a solid at room temperature. It was discovered in 1825 by Hans Christian Oersted in Denmark. Aluminium is one of the most used metals in the world as well as one of the most commonly found metals in the Earth’s
Aluminium Ore Introduction: Metals are currently in high demand by society. A high percentage of common everyday items you use and see utilises a form of metal. That wooden table in a common kitchen that looks like it is made completely of wood. Metals are still used in that "completely wooden table" as the screws used to hold it together are made of metals. Many commonly used metals such as iron, aluminium, and/or copper are all found from ores. An ore is a mixture in the form of a rock that is

adding carbon, the steel becomes harder and stronger and is more corrosion resistant than iron. Steel is malleable, and thus is easily welded and shaped into the forms needed to create car bodies. The cost of steel is low compared to metals like aluminium, which can also be used for car bodies but is expensive. Steel is plentiful and cheap. These properties make steel a suitable material for car bodies. By alloying copper – with the addition of nickel, cupro-nickel alloys have improved strength and
where it is sent to the blast furnace. The blast furnaces uses iron ore, sinter (agglomeration of iron ore, coke and flux fines), and coke to smelt and reduce the iron oxides into liquid iron. This is done by blasting hot in the bottom of the furnace, combusting the coke and producing reducing gasses which helps reduce the iron oxides into iron. Molten iron is then cast into ladles and sent to the BOS (Basic Oxygen Steelmaking) furnace. A lance is injected into the vessel with oxygen at supersonic
are also collected and made into sulfuric acid for use in hydrometallurgical leaching. The matte is recovered and moved to the converter, a cylindrical vessel into which the copper is poured. Air, lime and silica are added to react with the metal oxide. The slag is removed and the Sulfur dioxide and converted into sulfuric acid, this forms blister copper which is 97-99% pure. Blister copper then goes through the fire refining and then cast into copper anodes and placed in an electrolytic cell. Each

In a moisture containing atmosphere, corrosion will happen when these alloys are kept with some other metals with
Carbonate = Metal Oxide + Carbon Dioxide Malachite is an ore of copper. It is made mostly of copper carbonate. It can be crushed into a green powder. If this powder is heated it changes colour. A new substance has been made. The new substance is a black powder. This is called copper oxide. The copper carbonate has been decomposed. Copper oxide is made by thermal decomposition of copper carbonate. Carbon dioxide is also made. The formula for this is: Copper Carbonate = Copper Oxide + Carbon Dioxide
either missing or added) and break away into the water, where they can bond to oxygen ions, with which they can share electrons and produce their oxides. This is the same process iron ions go through when combining with oxygen ions in water to form iron
essay it will be pyrite that will be the primary sulphide considered. Acid mine drainage is not a new phenomenon, early mining techniques utilized gravity to avoid water pooling, resulting in the water becoming polluted by acid, iron, sulphur and aluminium (U.S.E.P.A., 2002). It is most commonly associated with coal mining, especially with soft coal, coal that has high sulphur content. The pyrite that is present in coal seams will be accessible after surface mining when the overlying surfaces are removed
Stainless steel is a type of alloy that has a very strong lattice structure (an arrangement/ shape of the crystals or other objects) which in some case can be more beneficial than others depending on the type of application it may be used for. In many cases this structure will make the material more suited to being used in engineering applications such as tools for instance a hammer (stainless steel alloys) , also they can be used for gears, engines, electrical motors and hydraulic systems because
