Magnesium Oxide Formula
Magnesium Oxide Formula
Students also refer to the magnesium source known as magnesia as the Magnesium Oxide Formula. The Magnesium Oxide Formula preparation reaction is also reversible, making it simple to recover the components by merely heating the molecule. To distinguish the Magnesium Oxide Formula from magnesia Negra, a black mineral that includes what is commonly known as manganese, it was historically referred to as Magnesia Alba (the white mineral of magnesia).
The Magnesium Oxide Formula is thermodynamically stable at pressures greater than 116 GPa, and, in line with the evolutionary crystal structure prediction, a semiconducting suboxide, Mg3O2, is thermodynamically stable at pressures greater than 500 GPa. The Magnesium Oxide Formula is also used as a model system for calculating the vibrational characteristics of crystals due to its stability.
Magnesium Oxide Formula and Structure
The Magnesium Oxide Formula is denoted as MgO. It has a molar mass of 40.304 g/mol or its molecular weight. Additionally, it has the empirical formula MgO and is made up of the ionic bonds between the oxygen ion O2 and the lattice magnesium cation Mg2+.
Furthermore, the Magnesium Oxide Formula produces magnesium hydroxide (Mg(OH)2) when water is present. Students can obtain the elements by separating the moisture, but this reaction is reversible.
Occurrence of Magnesium Oxide
The Magnesium Oxide Formula can be found in nature as the mineral periclase, which is the main source of magnesium. Additionally, the Magnesium Oxide Formula can be prepared at factories, research facilities, and labs.
Preparation of Magnesium Oxide
By calcining magnesium hydroxide or magnesium carbonate, students can make the Magnesium Oxide Formula. However, the last can be achieved by combining lime and magnesium chloride solutions, which are often made from seawater.
Additionally, the Magnesium Oxide Formula with variable levels of reactivity is produced by calcination at various temperatures. High temperatures, such as those between 1500 and 2000oC, reduce the amount of surface area that is available and create dead burnt magnesia, an unresponsive form that people use as a refractory.
Additionally, calcination at a lower temperature, such as 700–1000oC, creates light burn magnesia, a reactive form that is known as caustic calcined magnesia, whereas calcination at a higher temperature, such as 1000–1500oC, produces hard burn magnesia with a restricted degree of reactivity.
While some carbonate to oxide decay takes place at temperatures lower than 700oC, the resulting materials are released to reabsorb carbon dioxide from the atmosphere.
Properties of Magnesium Oxide
The Magnesium Oxide Formula appears as an odourless, white powder. The Magnesium Oxide Formula has a 3.6g/cm3 density. Additionally, its melting point is 2852oC and its boiling temperature is 3600oC). It dissolves in acid, ammonia, and water and creates magnesium hydroxide there. Alcohol, however, does not dissolve it. The material has a refractive index of 1.7355, a thermal conductivity of 45 to 60 W/m K1, and a heat capacity of 37.2 J/mol K.
Uses of Magnesium Oxide
Since Magnesium Oxide Formula is a solid and chemically and physically stable at high temperatures, people use it as a refractory material. The Magnesium Oxide Formula also has poor electrical conductivity and high thermal conductivity, both of which are advantageous. The Magnesium Oxide Formula is used as a food additive and is an anti-caking agent with the E530 code. People use the Magnesium Oxide Formula a lot as an electrical insulator in the heating elements of tubular construction. They also use it in heat-resistant electrical cables as an insulator.
Safety and health hazards of magnesium oxide
The Magnesium Oxide Formula irritates the eyes, and the respiratory system, and triggers an allergic reaction on the skin. Also, Magnesium Oxide Formula has extremely harmful and long-lasting impacts on aquatic life.
Solved Example for You
