Question

An element reacts with oxygen to form basuc oxide which reacts wuth dilute HCL to form a salt. is tge element a metal or non- metal? explain witg chemical equation.

Answer 1

Aluminium reacts with oxygen to form a basic oxide ( Aluminium Oxide ) .

4Al + 3O2 ------ 2Al2O3

And when it reacts with dilute HCl it leads to the formation of AlCl3 and H2O is released.

Al2O3 + 6HCl ------ 2AlCl3 + 3H2O

This Element is Aluminium and it is a metal

Answer 2

HEY MATE❤❤

HERE IS UR ANSWER ❤❤

⤵⤵⤵⤵⤵⤵⤵⤵

➡IT IS A NETAL BECAUSE METALS REACT WITH OXYGEN TO GIVE BASIC OXIDES.

➡THIS METAL OXIDES WHEN REACTS WITH DIL.

➡HCL GIVES SALT AND WATER .

FOR EAMPLE ,

➡ 2Mg(s) + O2(g) ----------> 2MgO(s)

➡ MgO(s) + 2HCL(dil.) ---------> MgCL2 + H2O(L)

HOPE IT HELPS U ❤❤
