Hydrogen gas, now a days, is not preferred to be used

Which of the following metals can be used for liberating hydrogen from dilute hydrochloric acid? Write reactions as well.
Magnesium, Gold, Copper.

Write reactions for the preparation of hydrogen from action of a reducing agent on an acid.

Consider the reaction.

${\mathrm{MnO}}_2\left(\mathrm{s}\right)+4\mathrm{HCl} \to {\mathrm{MnCl}}_2\left(\mathrm{aq}\right) + {\mathrm{Cl}}_2\left(\mathrm{g}\right) + 2{\mathrm{H}}_2\mathrm{O}$

Give the term used for such reactions.

Justify the position of hydrogen in the periodic table on the basis of similarity and dissimilarity with alkali metals and halogens.

Describe the procedure to prepare and collect hydrogen gas in a laboratory, with suitable diagrams.

Why Bosch process is preferred over laboratory method for industrial production of hydrogen?
