Which of the following reactions would be classified as oxidationreduction?
Check all that apply.
2Na(s)+Cl2(g)→2NaCl(s)
Na(s)+CuCl(aq)→NaCl(aq)+Cu(s)
NaCN(aq)+CuCl(aq)→NaCl(aq)+CuCN(s)

Best ResponseYou've already chosen the best response.0electrons have to be transferred from one element to the other, in the process of the reaction, so one is oxidized and the other is reduced.

Best ResponseYou've already chosen the best response.0@marmar10 interesting point, that might be where the point of confusion is. For your reference: "Any pure element—even if it forms diatomic molecules like chlorine (Cl2)—has an oxidation state of zero. Examples of this are Cu or O2." Na(s)+CuCl(aq)→NaCl(aq)+Cu(s) dw:1443492397750:dw Na goes from 0 to +1 so it's oxidized Cu goes from +1 to 0 so it's reduced. so electrons are lost from sodium and electrons are gained from copper.

Best ResponseYou've already chosen the best response.0i think your point of confusion was that any pure element has an oxidation state of 0

Best ResponseYou've already chosen the best response.0yes it makes a lot more sense now. I was looking in my book and it gave examples of ions so no wonder i was confused. Thank you

Best ResponseYou've already chosen the best response.0ugh.. yeah.. technically the first one can be classified as oxidation reduction too.
