Magnesium chloride is a neutral solid salt but hydrogen chloride is an acid gas. The chemical bonds in magnesium chloride are very strong ionic bonds in which the magnesium atom gives an electron to the chlorine atom so that they each have opposite electric charge and are drawn very closely and strongly together. The bonds in hydrogen chloride are covalent and much weaker because the elements do not exhange electrons so the atoms are not pulled together by electric forces.Thus the magnesium chloride is a high meltng point solid and thehydrogen chloride is a low freezing point gas.

What is compound is formed when magnesium reacts with oxygen?
When magnesium reacts with oxygen, it forms magnesium oxide (MgO). This is a compound composed of one magnesium atom and one oxygen atom. The reaction between magnesium and oxygen is a combination reaction, where the two elements combine to form a single compound. Magnesium oxide is a white solid with high melting and boiling points.
Magnesium oxide as a refractory lining material?
Magnesium oxide is used to make linings for some furnaces. It is known as a refractory material - which just means that it is resistant to heat.Magnesium oxide has a high melting point (2852°C) and so resists the high temperatures in a furnace. Its melting point is high because of the strong ionic bonds between the small Mg2+ and O2- ions.
Analysis test for magnesium oxide?
A common test for magnesium oxide is the Nessler's reagent test, where the presence of magnesium ions results in a brownish color. Another test involves reacting magnesium oxide with hydrochloric acid to produce magnesium chloride and water. Also, magnesium oxide can be identified through its characteristic white solid appearance and high melting point.
Why magnesium oxide has a high melting point and water has a low melting point?
This is simply due to the very different chemical make-up of the two substances. Atoms, ions, and molecules are arranged in particular ways to make up all matter, based on their specific chemical properties. It is because of this specific arrangement of atomic particles that give things their specific chemical and physical properties.
Of the following solids has the highest melting point H2Os Na2Os SO2s CO2s?
This element is wolfram (W): 3 422 oC.
What is magnesium oxygen?
Magnesium oxide is a compound that forms when magnesium reacts with oxygen. It is commonly used as a dietary supplement and in the production of materials such as cement and ceramics. Magnesium oxide has a white powder form and is known for its high melting point and chemical stability.

Does the oxide of Barium have a high or low melting point?
Barium oxide has a high melting point of around 1,923 degrees Celsius. This is typical for many metal oxides, as they tend to have high melting points due to the strong ionic bonds between the metal and oxygen atoms.
Does magnesium sulfate have a high melting point?
Magnesium sulfate has a high melting and boiling point, as it is made of Ionic bonds which are very strong. A lot of energy is needed to break them. So ionic compounds have high melting and boiling points. See related link for more information.
Why does aluminum oxide have a high melting point?
Aluminum oxide has a high melting point because it has strong ionic bonds between aluminum and oxygen atoms. These bonds require a significant amount of energy to break, leading to a high melting point. Additionally, the structure of aluminum oxide is a giant ionic lattice, which further contributes to its high melting point.

Is Magnesium melting point above room temperature?
Magnesium sulfate doesn't melt; at high temperature MgSO4 is thermally decomposed.

Magnesium sulfate doesn't melt; at high temperature MgSO4 is thermally decomposed.
Suggest a reason why magnesium oxide is used to line the inside of furnaces?
Magnesium oxide is used to line the inside of furnaces because it has a high melting point and is chemically stable at high temperatures. It also has good thermal shock resistance, meaning it can withstand rapid changes in temperature without cracking or breaking. This makes it ideal for protecting the furnace walls from the extreme heat generated during operation.
