Answer:
In the above question, the metal is X, while its oxide form is X2O3.
In this case the metal is Aluminium. It has a charge of +3, while the oxide has a charge of -2. So the oxide form of Aluminium is Al2O3.
On the other hand, the carbonate formulate for Aluminium is derived as follows:
Aluminium has a charge of +3, while carbonate ion has a charge of -2.
Application of the criss-cross methods indicates that the formula for aluminium carbonate is Al2(CO3)3
