<p>for the first one, i would imagine that N is 3- since NH3, has 3+ for H so N has to be 3-… but i think some cases (u gotta memorize) N is 3+.. or H is 3-… idk about that, the book might have an error. The second question, i am not 100% sure but yes, i think the most negative one is the oxidation equation… or i think that you can tell the diff between them by just looking at them, their format. I dont remember from the top of my head but i think when u see and electron on the right side, its reduction, and electron on the right side is oxidation, it could be vice versa so check up with that in the book lessons.</p>
<p>^ If the electron is on the left side of the equation, it’s reduction; if it’s on the right side, it’s oxidation.
Li+ + e- –> Li(s) would be reduction, since it’s gaining an electron (or you could say Li+ is an oxidizing agent)
One acronym to remember what’s oxidation/reduction is OIL RIG: Oxidation is Loss (of electrons), Reduction is Gain. There’s also “LEO IS A GERC” (Loss Electrons is Oxidation and Anode, Gain Electrons Reduction Cathode)</p>
<p>lol I know that fellas, thanks. Maybe I didn’t state the problem that clearly.</p>
<p>Both equations were writting in REDUCTION form b/c its in reductio form when stating the E (volt) charge.</p>
<p>Oh, haha, okay.</p>
<p>Well, looking at my data booklet, the equations with the most positive electrical potential are the strongest oxidizing agents, so they’d be the reducing equations. So yes, the most negative electrical potential would be the strongest reducing agents, and be the oxidizing equation.</p>
