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.
Chlorine is a powerful oxidising agent. It normally occurs as a gas but can be liquefied under pressure at ambient temperatures. As a dry gas it does not tend to be aggressive towards stainless steels, but as either a damp gas or dissolved in water it can be a corrosion hazard. Chlorine readily forms chlorides when in contact with gases such as methane, hydrogen sulphide and ammonia. Hydrochloric acid (HCl) can also be formed by these reactions.
