The nutrient breakdowns of whey protein and nutritional yeast are quite different. Protein powder, for example, gets more than 80 percent of its calories from protein, with a very small percentage coming from carbohydrates and about 15 percent coming from fat.
Zn + 2HCl H 2 + ZnCl 2 B. What gas was produced by the reaction of zinc and hydrochloric acid? How did this gas behave in the presence of fire? The gas produced by the reaction of zinc and hydrochloric acid was hydrogen. In the presence of fire Hydrogen explodes with a popping sound.
Reaction of zinc with air. Zinc metal tarnishes in moist air. Zinc metal burns in air to form the white zinc(II) oxide, a material that tirns yellow on prolonged heating.2Zn(s) + O 2 (g) â 2ZnO(s) [white].eaction 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).
