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 zinc was oxidized into Zn 2+ ions. This reaction is an oxidation reaction. The second part of this reaction involves the hydrogen ions. The hydrogen ions are gaining electrons and bonding together to form dihydrogen gas.xidation and Reduction Examples. Consider the reaction between zinc metal and hydrochloric acid. Zn(s) + 2 HCl(aq) â ZnCl 2 (aq) + H 2 (g). If this reaction where broken down to the ion level: Zn(s) + 2 H + (aq) + 2 Cl - (aq) â Zn 2+ (aq) + 2 Cl - (aq) + 2 H 2 (g). First, look at what happens to the zinc atoms.
