Question

what happen when Al, Zn and Fe reacts with dilute Hcl ? ​

Answer 1

Explanation:

when metal reacts with acid it forms salt + hydrogen gas

2Al+ 6Hcl -- 2Alcl3+ 3H2

Zn+2 Hcl--- Zncl2+H2

Fe+2Hcl---Fecl2+ H2

Answer 2

1) when Aluminium react with dilute hydrochloric acid it give Aluminium chloride (salt) and hydrogen gas releases

2Al +6 HCl gives 2AlCl3 +3 H2

2) when zinc react with dilute hydrochloric acid it give zinc chloride (salt) and hydrogen gas releases

2Zn + 2HCl gives 2ZnCl + H2

3) when iron react with dilute hydrochloric acid it gives iron chloride and hydrogen gas releases

2Fe + 2HCl gives 2FeCl + H2
