Answer:
a) Al2O3

Explanation:
Aluminum generally forms Al3+ ions.
Oxygen generally forms O2− ions.

So when the metal and the non-metal bond together they form a neutral compound, i.e. Al2O3
(i.e. 2×3−3×2=0).

The ionic bonding is so strong (due to charge magnitude) in this material that it is reasonably insoluble.

Chemical equation:

2KClO₃ → 2KCl + 3O₂

The given reaction is decomposition reaction.

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD  → AC +BD
