is the catalytic oxidation of ammonia a reversible reaction? my teacher talked about this, but i can't remember what she actually said.

Can anyone ''write'' this reaction: oxidation of vitamin c with potassium biiodate?

I'm currently writing an organic chemistry lab report, and for each experiment that we do when we write the lab report we must provide a real-world industrial use the procedure could give rise to. So anyone know any real world applications of the Jones Oxidation reaction?

I have a question: it is generally stated that 100 micrometers is the acceptable limit on the thickness of the oxidation layer on Zircaloy4 fuel rods. But I'm at loss as what is the reason for this limit ? Is it structural integrity ? Thermal resistance ? Mechanical tolerance ?

Why does nitrate (NO3-) have an oxidation state of +5? Doesn't it have 4 bonds to oxygen? Shouldn't that give it an oxidation state of +4?

What possible side reactions could occur in the oxidation of borneol? Since an acid-base rxn takes place when the NaOCl is added to the acetic acid, could that be considered a side-reaction since it gives rise to the chloronium ion or is there something else that happens after the production of...

I am working out a reaction and I was wondering if someone could tell me which oxidation state of chromium should be used? Cr(s) + AgNO3(aq) -> Cr(NO3)?(aq) + Ag(s) Do I use Chromium (II) Nitrate or Chromium (III) Nitrate? How do I know which one to use? If anyone could help explain...

Could anyone please help me with this? I don't have a clue where to begin. :frown:

1. The standard reduction potential for the half-reaction Sn4+ + 2e- Sn2+ is +0.15 V. Consider data from the table of standard reduction potentials for common half-reactions, in your text. For a galvanic cell under standard conditions, which of the following cathodic half reactions...

I'm trying to find out what type of reaction this is. a drop of water is added to a small pile of chemicals in a dish, after a few seconds, a blue flame and smoke is produced. NH4NO3 reacts to form (with chlorine as catalyst) N2O and water the experiment is called oxidation of zinc, so...

Hello, In a lab experiment, we filled 2 wells of a culture plate, one of them had 1.0 M CuSO4 and a piece of zinc metal, and the other well had 1.0 M ZnSO4 and a piece of copper metal. My question is: Which well has the reduced form of zinc and the oxidized form of copper? I know that...

i have to balance a redox reaction that contains the cyanide ion and other stuff. but before i can do anything, i have to assign oxidation states. would hte CN- have oxidation states of C being +4 and N being -5? so then would CNO- have C be +4, N be -2, and O be -2?

KMnO4 oxidation of benzylic methyl to acid sometimes does not proced. Is it necessary that solid starting material should soluble in this reaction mixture to proced the reaction.

I worked on this problem for quite a while last night and I'm not at all sure if my answers are correct. This is the problem I’ve been given: I know nitrogen exists in the 3-, 3+ and 5+ oxidation states. I would think that they would give me at least one of each. I'm REALLY not sure about b...

I'm having trouble determining the products of these reactions with bleach. I know for sure that all of these reactions do occur because it's part of a lab in which we find the stoichimetric coefficients for the reactants using calorimetry. Since they don't want us to be able to balance the...

At this moment, I'm on balancing redox equations. I'm stuck on step one though...:redface: 1. Assign oxidation numbers to all atoms in the equation... S + HNO3 --> SO2 + NO + H2O This particular problem is an example in my Chem book so I already know the answers. I just don't...

why does vanadium have maximum observed oxidation state of +5 while for Co the maximum observed oxidation state is +3? why are solutions of chromium(2) acidic? :confused: :confused:

Hello, Can someone show me a good site that helps explain how to determine oxidation numbers. I keep reading the same information in my textbook but I still don't have a clear idea on how to do that. Thank you

The book I'm reading, has suggested to methods for assigninig the oxidation statetes in a compound. The first method includes drawing the Lwis structure of the compound. And the second one is based on some rules. As I'm a beginner in chemsitry there are so many compounds which I can't draw...

nevermind i found the answer. However, i just want to know, is hydrogen always assigned the oxidation number of 1+? As well, how come having a negative oxidation number means nitrogen is a strong oxidizer? Or is this wrong? Can someone please explain this to me? Thanks.

We call reactions in which one species experiences both oxidation and reduction Disproportionation - but why do we chose this particular name? Thanks. :smile:

Hi ppl. I'm asked a question: Iron filings are added to a solution containing the ions Cu2+, Fe2+, Fe3+, H30+ and Zn2+. Deduce what reactions occur from the standard electrode potentials. Is this simply asking me which will change Fe2+ to Fe3+ and vice-versa by reduction or oxidation do you...

In a redox reaction I found, Hydrogen Peroxide (H202) was taken as having an oxidation state of zero However my chemistry teacher keeps telling me that oxygen ALWAYS has an oxidation state of -2 so that would mean the hydrogen in H202 must have an oxidation state of +2 to keep the molecule...

Oxidation States... I have read that the "idea of oxidation states is contrived." Why then do we use the idea and why does it work if it is not really the case? Why should we suppose everything acts like its ionic, etc? Thanks. :smile:

When writing oxidation states, is there a difference between 2+ and +2?

When dealing with an equation in which you combine 2 elements that have multiple oxidation states, let's say Magnesium and Nitrogen, which oxidation states do you assume you're working with? I know that in the instance of Magnesium and Nitrogen, it would have to be one of Nitrogen's negative...

Hi, It's been quite some time now I've spent on figuring out the mecanism of the oxydation of toluene with KMnO4 to give benzoic acid. My problem is i don't know how exactly the MnO4 attacks the hydrogen on the aliphatic chain. So, if anyone can help me figure out the first steps of which O...

Hello I had a few questions if anyone could help me out. I wanted to convert toluene into benzoic acid via side chain oxidation using potassium permanganate. However, I'm a little unsure of the mechanism. If I'm right, you convert toluene into benzyl alcohol using NaOH, and then from...

I saw this arcticle on popular science's web site: http://www.popsci.com/popsci/how2/article/0,20967,693558,00.html it tells about a way using mercury paste to make aluminum rust, very fast and crumble to dust. as you can see in their picture, it apearently is true, and as they explain in...

Hello My question is regarding the oxidative function of selenium dioxide (when reacted with carbonyl compounds). Selenium Dioxide converts an active methylene group to a carbonyl group -C=O, so the reaction of butan-2-one with selenium dioxide should form two products (corresponding to...

I'm not sure how to balance this equation with regards to the half reaction and electrons, as well as the elements: Fe+2 + Cr2O-27--->Fe+3 + Cr+3 Right now, I've gotten this far, though I don't know if it's the right track: Fe+2 + 2Cr+72O-27--->Fe+3 + 4Cr+3 + 7O-22 What should I do next?

what is the difference between oxidation number and ionic charges? I realize they are written differently, +1 vs. 1+, but how can I reasonably explain the differnces to 17 year olds (and myself?)?

Oxidation: Is there any reason for Potassium to react with excess oxygen to give a superoxide, not simple or pero-? Gary

Hello, I was curious if anyone could explain to me the simple procedure/guidleines to carrying out oxidation (half-reactions), reduction (half-reactions) and overall net reactions. I've read my Chem book over and over, but I don't quite understand it. Even a pointer to a good site with a...

Redox question: 12.53 ml of .05093 M selenium oxide (SeO2) reacted exactly with 25.52 ml of .1 M CrSO4. Cr+3 is formed. To what oxidation state is Selenium converted? I think that the ml + M stuff gives you the ratio between moles of SeO2 and moles of CrSO4 (1m SeO2 = 4m CrSO4). But how am...
