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 ...
Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper with an annual production of about 12 million tonnes. China is the largest producer country in the world, followed by Peru and Australia (Tolcin et al., 2011). About 70 % of the world’s zinc origi...
1. Identify the Reactants: - The metal we are using is zinc (Zn). - The acid we will use is hydrochloric acid (HCl).2. Understand the Reaction: - When zinc reacts with hydrochloric acid, it produces zinc chloride (ZnCl2) and hydrogen gas (H2). ...

Zinc sulphide, when reacted with dilute hydrochloric acid, gives zinc chloride and hydrogen sulphide. The chemical equation for the reaction can be given as, \({\rm{ZnS}} + 2\,{\rm{HCl}} \to {\rm{ZnC}}{{\rm{l}}_2} + {{\rm{H}}_2}{\rm{S}}\) ...
I have very fond memories of zinc because it's the first metal I melted and cast into many shapes as a wee lad. It's wonderfully suitable for casting because it's fairly non-toxic (certainly less toxic than lead), fairly low melting, and easy to get very cheap in the form of scrap...
Give at least three substances likely removed by washing the solid aldol product with dilute acetic acid in ethanol. A common way to make hydrogen gas in the laboratory is to place a metal such as zinc in hydrochloric acid. The hydrochloric acid reacts with th...
What happens when magnesium reacts with iodine to make magnesium iodide? Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate (Cu(NO3)2). What happens when copper is added to HCl acid? Explain. If you put copper metal into a solution of...
