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.
Reaction of zinc with acids. Zinc metal dissolves slowly in dilute sulphuric acid to form solutions containing the aquated Zn(II) ion together with hydrogen gas, H 2. In practice, the Zn(II) is present as the complex ion [Zn(OH 2) 6 ] 2+ .Zn(s) + H 2 SO 4 (aq) â Zn 2+ (aq) + SO 4 2- (aq) + H 2 (g).eaction of zinc with the halogens. Zinc dibromide, zinc(II) dibromide, ZnBr 2, and zinc diiodide, zinc(II) dibiodide, NiI 2, are formed in the reactions of zinc metal and bromine, Br 2, or iodine, I 2. Zn(s) + Br 2 (g) â ZnBr 2 (s) [white]. Zn(s) + I 2 (g) â ZnI 2 (s) [white].
