Question

Aluminium oxide melts at 2980°C while aluminium chloride boils at 178°C why?​

Answer 1

Answer:

Aluminium oxide (alumina, Al 2 O 3 ) has a high melting point because it is a covalent crystal with strong AlO bonds

Answer 2

Aluminium oxide melts at 2980°C while aluminium chloride boils at 178°C, because

• The Aluminum oxide will break down into aluminium and oxygen, as you already know.
• Because the two Adams, or components that makeup aluminium oxide, are used, it will break down when electricity is passed through it.
• Let's start with the skeletal reaction. Do you happen to have any aluminium oxide on hand? This is a good start, however, we still need to add the subscripts.
• Aluminium, as you may know, has a positive charge of three.
• Oxygen also has a negative charge. To balance this out, add it as a subscript for aluminium and three for oxygen least common denominators.
• As a result, this will decompose into aluminium, which is a solid, and oxygen gas. As a result, whenever you rate oxygen, you should also rate it as a gas.
• Then we must balance this equation. As a result, there are three oxygens on the reactant side and two on the product side. We'll need to use these common denominators to rebalance these.
• So, for oxygen, we'll use a three and for aluminium oxide, we'll use a two. Now let's take a look at each side. We now have six oxygens, and all we need to do now is balance the number of aluminiums with a four.

Hence, Aluminium oxide melts at 2980°C while aluminium chloride boils at 178°C
