Answer:
The element in your question my dear is ALUMINIUM (AL) Z=13
Explanation:
The element is Aluminium.
EXPLANATION:
:As according to your question,
The valency of the element =3
:Also it forms Amphoteric Oxide
:Hence, it's a group 3 element.
:As per the question the element is reactive than Iron and Forms Amphoteric Oxide, which is a group 3 element is more reactive than Iron.
:When this element i.e. Aluminium is reacted with Hydrochloric acid, the following reaction takes place-
| Al + HCl ------->AlCl3+H2 |
Ans. Hence the element M asked in the question is Aluminium and on it's reaction with HCl, Aluminium chloride (AlCl3) is formed along with release of H2 gas.
