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.
Magnesium oxide has a high melting point because of its strong ionic bonds between magnesium and oxygen ions. These bonds require a significant amount of energy to break, resulting in a high melting point for magnesium oxide. Additionally, the compact structure of magnesium oxide further contributes to its high melting point.
Magnesium oxide has a very high bond strength, which results from the fact that the difference in electronegativity of the two elements, magnesium and oxygen, is extremely high. To put it in other words, the very negatively charged oxygen and the very positively charged magnesium atoms will strongly attract eachother. This tends to hold them in place against the tendency of heat to break them apart, hence, a high temperature is need to melt this compound.
Magnesium chloride is ionic compound. There is a strong electrostatic force of attraction between 2 chloride atoms and 1 magnesium atom. The bond holding the atoms together is known as ionic bond. A high heat energy have to be applied to break the strong bond holding the atoms, resulting the compound to record a high melting point.
As for every magnesium atom there are two chloride atoms attached which makes the strength of the bond quite strong. Therefore, a lot of energy is required to break it which is why it has a high melting point.
Because of the Strong ionic bond between the ions in the compound i.e Mg2, Br-1
they require a lot of energy to brake hence the high melting point
Because the ions are held together by very strong forces and to melt, you need the ions to break apart.
Sodium and magnesium chlorides are solids with high melting and boiling points because of the large amount of heat which is needed to break the strong ionic attractions.

What is compound is formed when magnesium reacts with oxygen?
Magnesium oxide is formed when magnesium reacts with oxygen. This compound is a white solid that has a high melting point and is commonly known as magnesia.
Magnesium oxide as a refractory lining material?
Magnesium oxide is commonly used as a refractory lining material in high-temperature applications due to its high melting point, resistance to thermal shock, and ability to withstand extreme heat. It forms a protective layer that can help prevent corrosion and erosion from hot gases and molten materials in furnaces and other industrial processes. Additionally, magnesium oxide has good thermal conductivity, which can help with even heat distribution within the refractory lining.
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?
Magnesium oxide has a high melting point due to its strong ionic bonds between magnesium and oxygen ions, which require a lot of energy to break. Water has a low melting point because it is held together by weaker hydrogen bonds that can be easily disrupted at lower temperatures.

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.
Is magnesium sulphate's melting point above room temperature?
Yes, magnesium sulfate's melting point is above room temperature. It has a melting point of 1,124 degrees Fahrenheit (607 degrees Celsius), which is much higher than typical room temperatures.
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.
