An exposed metal nail forming rust Cu Oxidation is defined as the loss of electrons. Mg + Cu 2+ → Mg 2+ + Cu ? The average of four numbers is 26. oxidation neither reduction. Answer : The option (C) is not an oxidation-reduction reaction. -2. Metals react with oxygen in the air to produce metal oxides. A restaurant manager states the number of customers that enter the Mg ? Mg(s) + Cl 2 (g) → MgCl 2 (s). Depending on the chemical reaction, oxidation and reduction may involve any of the following … An oxidation-reduction reaction happens when hydrogen, oxygen or halogen atoms are transferred, so in this case, your answer would be B. 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. If the oxygen atoms are not balanced in either reaction, add water molecules to the side missing the oxygen. This case can be solved trivially without memorizing anything as in the first three reactions an element is a reactant, and the fourth reaction is a neutralization reaction. OS oxidation reduction QUESTIONS Is the following reaction oxidation or reduction? 2C(s) + O 2 → 2CO(g). restaurant is equal to 3 times the number of people that buy a hotdog from Example 1.
