Hydrogen gas is produced: Zn + 2HCl â ZnCl2 + H2â + Î´Q   Zinc (Zn) reacts with Hydrochloric Acid (HCl) to produce Zinc Chloride (ZnCl2), Hydrogen Gas (H2), and He â¦ at. 6 people found this useful.
It is also prepared from metallurgical grade silicon in a two-step process. First, silicon is treated with hydrogen chloride at about 300 Â°C to produce trichlorosilane, HSiCl 3, along with hydrogen gas, according to the chemical equation: Si + 3 HCl â HSiCl 3 + H 2. The trichlorosilane is then converted to a mixture silane and silicon tetrachloride.
