aqueous magnesium chloride is not used to extract magnesium. explain why [3 marks]
Answers
Answer:
Explanation:Magnesium chloride, MgCl2, dissolved in seawater, is an abundant, natural source of the very useful metal magnesium. Magnesium is a common component of alloys. Alloys are produced by combining a pure metal with one or more other elements to form a new substance with desirable properties. (Steel, for example, is a common alloy of iron and carbon.) Magnesium alloys are found in aircraft, automobiles, rockets, luggage frames, portable power tools, cameras, laptop computer casings and mobile phones.
Magnesium lends lightness and strength to alloys--a real plus for the owners of fuel-consuming vehicles, or travelers carting luggage. And magnesium alloy construction helps dampen the noise and vibration associated with the use of hand-held power tools, such as electric drills and nail-shooting guns.
Answer:
A single replacement reaction, also known as a single displacement reaction, occurs when one element in a molecule is exchanged with another. Starting substances are always pure elements combined with an aqueous compound to give a solid compound and liberates hydrogen gas.
Explanation:
Aqueous magnesium chloride is not used to extract magnesium because the magnesium will rapidly react with the water if we do it in an aqueous solution.
The reaction of magnesium with water is as follows below:
Mg (s) + H₂O (l) → MgO (s)+ H₂ (g)
It is an example of a single replacement reaction.
Hence, the aqueous magnesium chloride is not used to extract magnesium because the magnesium will rapidly react with the water if we do it in an aqueous solution.
