Question

metal react with acid and release hydrogen gas give its reaction​

Answer 1

Metal+acid------->metal salt +hydrogen gas

for example

HCl+Zn------->Zncl2+H2

Answer 2

$\underline {\Huge \mathfrak {Answer ;}}$

When metals react with dilute acids, the products formed are salt and hydrogen gas.

$\boxed {Metal+dilute\:acid→Salt+Hydrogen \:Gas}$

For example,

Fe + 2HCl → FeCl2 + H2 gas

Mg + 2HCl → MgCl2 + H2 gas
