Zinc (Zn) is a metal, and hydrochloric acid (HCl) is an acid. When these two substances react, the zinc atoms lose electrons to form Zn2+ ions, while the hydrogen ions from the acid gain electrons to form hydrogen gas (H2). The chloride ions from the hydrochloric acid combine with th...

To solve the question "Alkyl halide on reduction with Zn + HCl gives", we will follow these steps:Step 1: Understand the Reactants - The reactant is an alkyl halide, which can be represented as R-X, where R is an alkyl group an
Question: If {eq}25.00\ g {/eq} of {eq}\rm Zn {/eq} reacts with {eq}\rm 30.00\ g\ MnO_2 {/eq}, what mass of {eq}\rm Zn(OH)_2 {/eq} will be produced? Batteries and Cell: Cell and batteries are used for generating electricity from the chemical rea...
Given 65 g of Zn and 65 g of HCl, what is the limiting reactant and reactant in excess in the reaction: Zn + 2HCl arrow ZnCl2 + H2? A student used 3.27 g of Zn to react with excess HCl and obtains 6.47 g ZnCl_2. What is...
Observation. A colourless gas is evolved with brisk bubbles from the test tube. When a burning match stick is brought near the gas, then the gas burns with a pop sound. The gas evolved is H(2) gas. H(2) gas is used as fuel in the space crafts.
The reactant with higher redox potential can be spontaneously galvanically replaced by another reactant showing lower redox potential in solutions. Due to the lower redox potential of Zn2+/Zn, Zn/Sn, Zn/Sb, and Zn/Bi interfacial layers can be in situ formed on anodes, which not only ...
In a Z-scheme heterojunction, electrons and holes react separately on the surfaces of different materials, reducing the probability of recombination and improving the sustained efficiency of photocatalytic reactions [7], [8]. The electron-hole separation structure formed in the Z-scheme heterojunction ...
