Which of the following is not an oxidation-reduction reaction? A. Ca + 2 HCl ---> CaCl2 + H2 B. H2 + Cl2 ---> 2 HCl C. NaCl + LiNO3 ---> NaNO3 + LiCl D. 2 CO + 2 NO ---> 2 CO2 + N2
I think the correct answer from the choices listed above is option C. The reaction NaCl + LiNO3 ---> NaNO3 + LiCl is not an example of an oxidation-reduction reaction. It is a double replacement type of reaction. Hope this answers the question.
