Everyone has the HD gene, but in some families an abnormal copy of the gene gets passed from parent to child. If you have a parent with Huntington's disease, you have a 50% chance of having the gene and developing the disease. Also: Men and women are equally likely to inherit the abnormal gene.
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.
The formation of highly reactive anhydrous HCl gas formed when zinc chloride hydrates are heated is the basis of qualitative inorganic spot tests. The use of zinc chloride as a flux, sometimes in a mixture with ammonium chloride (see also Zinc ammonium chloride), involves the production of HCl and its subsequent reaction with surface oxides.
