Question

A displacement reaction is given below
X+ZnSo4 --->XSo4+zn (hint:X is a metal)

A) analyse the reactivity order given below and identify the possible metal X

B) which the chemical equation which shows the change according to Zn^2+ions in the reaction?

C) Whether the change in Zn^2+ ion in oxidation or reduction? Why?
​

Answer 1

Answer:A.Na ,B.When zincoxide reacts with hydrogen it gives zinc +2ion,C. oxidation

Explanation:

a. Na +ZnSo4⇒NaSo4+Zn

b. Zno+H2⇒Zn+H20

Zn+2electron⇒Zn²+ion

c. Zn is oxidation.Because of the renoval of oxygen.
