When zinc reacts with hydrochloric acid, what is produced? A. Zinc chloride and oxygen. B. Zinc sulfate and hydrogen. C. Zinc chloride and hydrogen. D. Zinc oxide and water. 相关知识点: 试题来源: 解析 C。中文解析:锌和盐酸反应生成氯化锌和氢气。选项 A 生成氧气错误;选项 B 生成硫酸锌...
Yes, it is obvious that copper will not react with hydrochloric acid for the simple reason it's below hydrogen in the reactivity series. So,copper cannot replacethe hydrogen in HCl to form CuCl2 . Hence, when copper (Cu) reacts with hydrochloric acid (HCl) there will be no reaction. Why...
Zinc metal reacts with hydrochloric acid to produce hydrogen gas and zinc chloride (write a balanced equation). When 0.154 g of Zn(s) is combined with enough HCl (aq) to make 50.0 mL of solution in a Zinc metal reacts with excess hydrochloric acid to pro...
In the present paper, the hydrometallurgical processes have been described for the recovery of zinc from the secondaries using sulphuric acid, hydrochloric acid, ammoniacal solution and sodium hydroxide etc. as lixiviants. The leach solution thus obtained has been purified with respect to dissolved ...
Odor Control: It reacts with sulfide to minimize release of H2S gas in waste treatment facilities. Oil-Gas Wells: High-density solutions of Zinc Chloride and calcium chloride give good performance in well completion and work-over operations; the solutions also used as packer fluids under certain...
Zinc burns in air with a bright bluish-green flame, giving off fumes of zinc oxide.[35] Zinc reacts readily with acids, alkalis and other non-metals.[36] Extremely pure zinc reacts only slowly at room temperature with acids.[35] Strong acids, such as hydrochloric or sulfuric acid, can...
(2) the obtained tin sludge is reacted with the concentrated hydrochloric acid to make the tin sludge convert into the tin ionic condition; (3) the tin ion which is in the ionic condition is reacted with the zinc salt under a certain condition to synthetize the zinc hexahydroxystannate ...
When zinc chloride reacts with oxidizing agents, ozone is formed along with hydrogen gas and water vapor. It specifically reacts with oxidizing agents and does not react with acids or strong alkalis. 5. Nucleophilic Properties Zinc chloride can be used to create Grignard reagents, although caution...
The first of these may be considered the dezincking operation proper in which the zinc coating is reacted with hydrochloric acid to form zinc chloride, and the second may be considered as a boiling operation in which the zinc chloride solution obtained from the dezincking operation is boiled ...
