Web1. Laboratory Preparation of Dihydrogen. (i) Typically, hydrogen is created when powdered zinc reacts with diluted hydrochloric acid. Zn + 2H+ → Zn2+ + H2. (ii) Zinc and aqueous alkali can also be combined to create hydrogen. The reaction is given below: Zn + 2NaOH → Na2ZnO2 + H2. 2. Commercial Production of Dihydrogen. Webthat the Hydrogen Shot target by the U.S. Department of Energy 7 of producing clean hydrogen at a cost of $1.0/kg by 2030 is ambitious but not unrealistic. Because electricity prices will become the dominant component of the life-cycle cost of hydrogen by 2030, the attainment of the Hydrogen Shot target via electrolytic hydrogen ultimately
