Which property of calcium oxide does the lattice structure explain?
according to my calculations it explains the high melting point
Does the oxide of Barium have a high or low melting point?
High melting point
Why does aluminum oxide have a high melting point?
it has a giant ionic lattice structure containing oppositely charges ions. these take alot of energy to break, and the substance therefore has a high melting point
Is calcium a nonmetal or a metalloid?
Calcium is considered a Metal since is in position 2 of the periodic table, it is also malleable which is a property of metals and it has also a high melting and boiling point (as shown below) also a property of metals. It can be beaten into extremely thin sheets. It can be pressed, rolled, and cut.Melting point is 851 degrees Centigrade.Boiling point is 1482 degrees Centigrade.
Does chlorine have a high melting point low boiling point etc?
low melting point, it is a gas at room temperature....

Does the oxide of Barium have a high or low melting point?
High melting point
Is calcium liquid at room temperature?
No it is a solid. Calcium has a high melting point. Most metals (except mercury) have high melting points.
Does rust have a very high melting point?
The melting point of the oxide Fe2O3 is 1 565 oC.
What type of physical properties are in a calcium oxide?
Some physical properties of calcium oxide are:- density: 3,34 g/cm3- melting point: 2 613 oC- boiling point: 3 850 oC (at high pressure)- crystlline structure: face-centered cubic- enthalpy of formation: 635 kJ/mol
Is calcium chloride soluble in water?
because it has high melting/dissolving point.
Why does aluminum oxide have a high melting point?
it has a giant ionic lattice structure containing oppositely charges ions. these take alot of energy to break, and the substance therefore has a high melting point
What is the melting and boiling point of zinc oxide?
Melting point of zinc: 787,15 0F Boiling point of zinc: 1 655 0F
What is the calcincation of calcium oxide?
Calcination is the heating of an ore at high temperature. Calcium carbonate undergoes calcination to give calcium oxide. Calcium oxide doesn't undergo calcination.
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.
Does chromium have a high low melting point?
high melting point
Does carbon have high melting point?
it has a low melting point
