Question

asseration (A) aluminium oxide is an amphoteric oxide reasion (R)aqarance​

Answer 1

Answer:

Here,'√'is the radical symbol used to represent the root of numbers. ... The positive number, when multiplied by itself, represents the square of the number. The square root of the square of a positive number gives the original number. For example, the square of 3 is 9, 32 = 9 and the square root of 9, √9 = 3..it's for your helpful

Aluminium oxide reacts with both acidic and basic substances to give neutralization reaction and hence cannot be called a true acid as well as base. Hence it is called amphoteric oxide.

Al 2 O  3  +6HCl→2AlCl  3 +3H  2 O>> Neutralisation Reaction with hydrochloric acid ( behaves like a base )

Al 2  O  3 +2NaOH→2NaAlO  2  +H  2 O>> Neutralisation reaction with Sodium hydroxide ( behave like an acid )

(b) lonic compounds are bound to each other with strong attraction force. Hence they are in solid form and their ions are not mobile. When in molten state the ions become mobile and act as carriers for charge and hence conduct electricity.
