Concept introduction:
Hydrogen is a minor component of atmosphere as well as Earth’s crust. It is one of the most important substances in inorganic chemistry, as it is used as the precursor of many compounds. Hydrogen gas is very good reducing agent. It is used in the reduction of different metal oxide to their respective metals by heating at high temperature. It is one of the components of water also.
(c)
Interpretation:
The chemical reactions for the preparation of hydrogen gas from Mg(s) should be determined.
