Question

Which chemical reaction falls under the study of electrochemistry?
a) SO3(g) + CaO(s) --> CaSO4(s)
b) Zn(s) + Cu^2+(aq) --> Zn^2+(aq) + Cu(s)
c) SO2(g) + H2O(l) --> H2SO3(aq)
d)CaCO3(s) --> CaO(s) + CO2(g)

Answer 1

the chemical reaction b) Zn(s) + Cu^2+(aq) --> Zn^2+(aq) + Cu(s) falls under the study of electrochemistry as it involve ions dissolved in solution. these are electrolytic solutions capable of transferring eletrons.

Answer 2

B. Zn(s)+Cu^2+(aq)-> Zn^2+(aq)+Cu(s) 
its the correct answer on    ed gen uity
