    I thought the poem was great :)

    Reaction for G-3-P oxidizing to 1,3-BPG

    I am no biologist but I think it is Cytochromes in the mitochondrial inner membrane.

    Electromagnet that plug into wall outlet?

    Yes your right, I guess it would. My major concern here was safety, but I think my point is moot since you suggested it was not worth doing.

    Electromagnet that plug into wall outlet?

    Are you suggesting he run straight from AC through a 120 ohm resistor the size of a brick and through his coil of wire? I have to assume that is what you mean since you are suggesting a 120W resistor. 1A @ 120V = 120W. AC source as a magnet would not work as the voltage alternates polarity...

    VSEPR model

    Eli is correct. I am sorry for my misinformation. http://en.wikipedia.org/wiki/Oxygen_difluoride By the way, What book are you using?

    VSEPR model

    For the OF2, I think it is due to the formal charges. O and F are both negative, where in the case of H2O the O is neg and the H is +. This is my first year of chem, so I may be wrong.

    Color of solution

    I think ligands and crystal field theory are more of a Chem II subject. I say this because that topic is near the end of my chem book (Brown Lemay et.al) and our book is a 2 semester book, so I assume Chem II. I am just now completing chem I, and we never covered Ligands and Xtal theory.

    Electronegativity Confusion

    Ok, I think I got my answer. On one side of the membrane are K+ ions, the other side is Na+ ions. A potassium channel allows K+ ions to move freely between the membranes, until equillibrium of K+, so one side has more +1 ions than the other side, resulting in a net potential of -70 mv.

    Electronegativity Confusion

    So let me ask. If you had a Sodium atom on one side of a membrane, and a potassium on the other side, and were some how able to place a meter across each membrane, which side would read more positive? I am still trying to relate this to the membrane potential of a neuron. Thanks

    Electronegativity Confusion

    [SOLVED] Electronegativity Confusion Homework Statement Looking at the periodic chart and going down, the electronegativity goes down, ie Na = .9 and K = .8 From the definition electronegativity is the ability to attract electrons. So is that to say the more electronegative would actually...

    Percent of solution

    So by that you mean, Mass of solute/100 mL solution? So I think that would equate to .5 gram C6H12O6 @ 10mL Does that sound correct?

    Ionic equations and Spectator Ions question REALLY SHORT

    To balance I think you get Pb(NO3)2(aq) + H2SO4(aq) --> PbSO4(s) + 2HNO3(aq) if that helps any.

    Ionic equations and Spectator Ions question REALLY SHORT

    Could Snazzy be saying you won't get HNO3? rather H + NO3 ???

    Percent of solution

    I wish I could, but as you can see, I am not that good at chem. Thanks for the assist :)
