Great, thank-you! And as a follow up to all this and as a conclusion...in the I2 (aq) + I- (aq) <----> I3- (aq) equation if any of the reagent's concentration was changed...this would affect the iodine distribution between the two liquids, correct? But, let's say I3- was increased would that...

Homework Statement I'm studying the equilibrium of I2 and its distribution in two immiscible liquids (varsol and aqueous potassium iodide). Since I2 is non polar; it will "prefer" to be in varsol but since KI (aq) is an ionic salt solution, iodine will also dissolve to give the I3- ion. When...

Oh my goodness, that makes complete sense...to be honest I didn't even clue in that this was a redox reaction. Thank you.

Hello, Thanks for all the help. I don't know why Paulham and I are so confused but I don't seem to see the matter clearly either. I understand the theory behind it and how NaOH will remove some H+ from the reactants side shifting the reaction to the left but it's the actual chemical equation...

Hello, Thanks for the reply. What would make a carbon more electronegative? Aren't atoms of the same element equally electronegative? If anything, I guess, wouldn't the triple bond be the most electronegative? If that's the case, why would it be more electronegative? Thanks!

Homework Statement Label the acid hydrogen in each of the following compounds and arrange them in order of increasing acidity and explain the trend. Homework Equations N/A The Attempt at a Solution I'm not quite sure what the question means by "label" the acidic hydrogen but I believe...

O.k... 5-sec-butyl-2-dimethylnonane is the only other answer that kind of makes sense to me...beyond that I'd just be guessing :confused:. Thanks for the help.

Ah yes, "buto" is definitely not a proper name. Also, I forgot to place the substituents in alphabetical order; Butyl should be written before dimethyl correct? I'm not sure what you mean by the "shape of the side chain". Is it that butyl group is in fact "iso-butyl"? Does this look better...

Homework Statement Provide an acceptable name for the alkane shown below. Homework Equations N/A The Attempt at a Solution I never get these right but...my guess would be 2-dimethyl-5-butononane? My reasoning: the longest carbon chain has 9 carbons so the base name would be nonane, there...

O.k I understand thanks. Does this look better? 2CrO42- + 2H3O+ + NaOH <--> Cr2O72- + 4H2O

Homework Statement Determine the hybridization of the atoms labeled A, B and C in the molecule and the bond angles around them. Homework Equations N/A 3. The Attempt at a Solution A. Normally, I would say it is sp3 for oxygen since there are 4 groups attached to it including the lone...

Thank-you for the help. So, would this reaction equation be correct? 2CrO42- + 4H3O + 2NaOH <--> Cr2O7 2- + 7H2O + 2Na

Ah! :) good point! So then, my thoughts becomes; since hydronium is one of the reactants, if we lower the concentration of hydronium by adding sodium hydroxide to neutralize some of the acid then the equilibrium would shift left?

Homework Statement Without adding any Chromium based compounds, how would you manipulate the above equation to produce more CrO42- ions? Be sure to use chemical equations to show the answer. Homework Equations 2CrO42- (aq) + 2H3O+ <--> Cr2O72-(aq) + 3H2O (l) The Attempt at a Solution So my...

Ah interesting...thank you! so...although fission stops, still a lot of heat is produced by radioactivity so there is still definitely a problem. I choose (A).
