great Questions :)

$\huge \mathfrak \orange{❥Answer}$

★ zinc

✪ ADDITIONAL INFORMATION

★ The zinc is ideal for the preparation of hydrogen gas in chemical laboratories because it usually contains a small amount of copper, which has the ability to act as a catalyst to the associated chemical reaction and, therefore, increase the rate of the chemical reaction without actually participating in it.
