Best ResponseYou've already chosen the best response.0So oxired reactions charge from one side to the other, and A does do that with Ba... Wow, now I know why it's wrong

Best ResponseYou've already chosen the best response.0The best way to answer this kind of (defition related) questions is to understand what the definition means, and learn about it. Here is a link that will give you the answer (and more): http://www.shodor.org/unchem/advanced/redox/

Best ResponseYou've already chosen the best response.0Let me explain. OxidationReduction reactions are the one in which from reactants to products side, there has been loss and gain of electron in at least 2 different elements. NB: The oxidation number of an element in its standard state is 0. C answers it because at the reactants side, Zn has oxidation number 0 and on the products side, has oxidation number +2. On the other hand, the Zn could have lowered its oxidation number on the products side, given that the oxidation number of S can also change, affecting the Zn's. Hydrogen in the reactants side had oxidation number +1 and in the products side, 0. Meaning, it reduced. Zn also appeared to reduce. At the end of the day, we cannot find the element which oxidized, hence it is not an oxidationreduction reaction.

Best ResponseYou've already chosen the best response.0Then the answer must be A. Because in both B and D, the reactants had 0 oxidation numbers and in the products side, one of them increased and the other reduced, making them reduction  oxidation reactions.
