Question

Consider the redox reaction below. Upper Z n (s) plus 2 upper H upper C l (a q) right arrow upper Z n upper C l subscript 2 (a q) plus upper H subscript 2 (g 0). Which half reaction correctly describes the oxidation that is taking place? Upper Z n superscript 2 plus (s) plus 2 e superscript minus (a q) right arrow upper Z n (s). Upper Z n (s) right arrow upper Z n superscript 2 plus (a q) plus 2 e superscript minus. 2 upper H superscript plus, plus 2 e superscript minus right arrow upper H subscript 2. Upper H subscript 2 plus 2 e superscript minus right arrow 2 upper H superscript plus.

Answer 1

Answer:

Cuo+H2---->Cu+H2o

this reaction have both reduction and oxidation so they are called as redox reaction when oxidation and reduction as use of electron and gain of electron would always give redox reaction this has been told in this question
