Why is HF a liquid and HCL a gas? Best Answer: The simple answer is because HF has stronger intermolecular forces of attraction than HCl does. Since the molecules are more strongly attracted, they have to have a greater average kinetic energy in order for them to escape as a gas.

- Abstract. The zinc and ammonia values in solutions containing zinc chloride or zinc monoammine chloride and ammonium chloride can be recovered by adding ammonia to a pH of about 5.5 to about 8.5 and separating the precipitated zinc diammine chloride from the residual aqueous solution of ammonium chloride.

Zinc (Zn) and water The ion does form a protective, water insoluble zinc hydroxide (Zn(OH) 2) layer with dissolved hydroxide ions, according to the following reaction mechanism: Zn 2+ + 2OH - 2 (s). Zinc reacts with H+ ions, according to the following reaction mechanism: Zn(s) + 2H + 2+ (aq) + H 2 (g).This reaction releases hydrogen, which reacts with oxygen explosively.inc is naturally present in water. The average zinc concentration in seawater is 0.6-5 ppb. Rivers generally contain between 5 and 10 ppb zinc. Algae contain 20-700 ppm, sea fish and shells contain 3-25 ppm, oysters contain 100-900 ppm and lobsters contain 7-50 ppm.

"Answer to Question #10245 Submitted to ""Ask the Experts""" In old uranium mines, the ventilation was often poor, and the radon progeny were close to equilibrium with the radon. The progeny in equilibrium with 100 pCi L-1 (3,700 Bq m-3) radon gas would release approximately 130,000 megaelectronvolts (MeV) of alpha energy in decay, so the WL was defined as: 1 WL = 130,000 MeV alpha energy per liter of air

It's Elemental Zinc is pronounced as ZINK. History and Uses: Although zinc compounds have been used for at least 2,500 years in the production of brass, zinc wasn't recognized as a distinct element until much later. Metallic zinc was first produced in India sometime in the 1400s by heating the mineral calamine (ZnCO 3) with wool. Zinc was rediscovered by Andreas Sigismund Marggraf in 1746 by heating calamine with charcoal. Today, most zinc is produced through the electrolysis of aqueous zinc sulfate (ZnSO 4). Roughly one third of all metallic zinc produced today is used in a process known as galvanization. During galvanization, an object that is subject to corrosion, such as an iron nail, is given a protective coating of zinc.

- The zinc patina is formed by the conversion of zinc metal into corrosion products through interaction with the environment. The first products formed include zinc oxide and zinc hydroxide. Later in the corrosion cycle these products interact with carbon dioxide in the environment to form zinc carbonate.

Hydrogen chloride Hydrogen chloride. Hydrogen chloride, (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A solution of the gas in water is called hydrochloric acid. 1  Hydrogen chloride may be formed by the direct combination of chlorine (Cl2) gas and hydrogen (H2) gas; the reaction is rapid at temperatures above 250° C (482° F). 2  Hydrochloric acid is prepared by dissolving gaseous hydrogen chloride in water.
