Question

8) word equation for zn+ cacl2 gives zncl2+ cu
A) zinc + Hydrochloric acid zinc chloride + Hydrogen
B) zinc + cupric chloride –
zinc chloride + copper
c) zinc + sulphuric acid _ zinc sulphate + Hydrogen

D) zinc + copper chloride _ zinc chloride + copper​

Answer 1

Answer:

CuCl2 + Zn → ZnCl2 + Cu - Balanced equation | Chemical Equations

Explanation:

The reaction between zinc and hydrochloric acid is Zn + HCl = H2 + ZnCl2. It is a single replacement reaction where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt. Zinc reacts quickly with the acid to form bubbles of hydrogen.

Zinc and Copper Chloride Zn + CuCl2 ---> ZnCl+ Cu

In this reaction, Zinc is the higher series and copper is lower. The atoms of the more reactive metal push their electrons on to the ions of the less reactive metal. ... This is because copper is being formed during the reaction, meaning that new bonds are being formed.
