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...
34 Hydrochloric acid reacts with zinc.2HCl(aq)+Zn(s)→2nCl_2(aq)↓+H_2(g)What will increase the rate of this reaction but will not change the Boltzmann distribution of molecular energies? B1 addition of a suitable catalyst2 an increase in concentration of hydrochloric acid3 an increase ...
This process dissolves the zinc to make a solution of zinc sulfate and other acid-soluble metals. Iron is precipitated and filtered from the process as a residue. Depending on the ore, the residue may also contain lead, copper, silver, and gold. Cadmium is not removed in the iron ...
What happens when you react Vitamin C to acid? What happens when sulfur reacts with iron? Does it make any colors before it turns dark grey? If a nickel rod embedded in a silver nitrate solution, what do we predict? explain. What will happen when iron reacts with steam? What happens ...
Batteries generate electricity by allowing two chemicals to react with each other in a way that releases electrons, which are tapped and fed through a wire to do useful work. In most batteries both chemicals are present in the battery and they stay there: It's a sealed system. Fuel cells,...
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...
Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s) This spontaneous reaction was used first in 1830 to make a voltaic cell. The metal is attacked by mineral acids. Reactions with sulfuric and hydrochloric acids produce hydrogen. With nitric acid, no hydrogen is evolved but the pentavalent nitrogen...
2.6 Color/Form White to beige to light brown 2.7 Water Solubility Sparingly soluble in hydrochloric acid, nitric acid, and ammonium hydroxide. 2.8 Stability hygroscopic3. Use and Manufacturing3.1 Description Zinc fluoride, with the chemical formula ZnF2, has the CAS number 7783-49-5. It appears...
Step by step video & image solution for Which gas is liberated when dilute hydrochloric acid reacts with zinc metal ? Write a balanced chemical equation for the reaction which takes place. How will you test this gas ? Name a metal which produces the same gas just by reacting with cold wat...
