    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.

    Percent of solution

    Okay, let's see if I got this right. Since the solute is H2O, I assume 1 molar H2O. Since 1 mole H2O = 18 grams/mole and I use the molarity formula to get grams. 10mL of H20 or .01L x 1 molar = .01 grams of H20. ergo .01g H2O x 5% = 5 x 10^-4 gram glucose, or .0005 gram. Is that correct...

    Percent of solution

    [SOLVED] Percent of solution Homework Statement Let's say we have 5% glucose of a 10 mL solution. So that would imply that .5 mL of the solution is glucose, but that does not really tell me how much glucose. Is it assumed that the glucose is 1 molar? I ask because in one of my bio...

    Le Chatelier's Principle - What is an equilibrium shift?

    Equations go back and forth from reactant side to product side. In other words you go from NaCl to Na + Cl back to NaCl. So, to the right would mean more Na + Cl. I think thats right, maybe someone will smack me for error.

    Electron Config of Mn +4

    Thanks for the response. To be honest I had to look up ligands in my book. It is covered in Chap 24 of my book, I am on chap 6-7 (Electron Configurations). So what you said went way over my head. BTW the book I am using is Chemistry The central science by Brown lemay Burstein. Thanks for...

    Electron Config of Mn +4

    Homework Statement I am a little unclear on the electron configuration of ions. For example; Mn +4 would seem to be 4s2 3d1, but instead it is 3d3. Ok, I get that an atom is stable at half full, or full, but it is not clear to me why 3d3 is anymore stable than 4s2 3d1. Could someone help...

    Need help with take home test

    A strong acid has a low pH; for example HCl is around pH of 2. A high pH would indicate a base. A strong acid would not have more OH, so your wording is confusing.

    Which kind of graphing calculator should I buy?

    The HP looks pretty slick. Never used it. I personally love my TI83. I also have a Casio CFX-9850, and found it weak in comparison to the TI. This is just my opinion.

    Finding limiting reactant

    Since you know the molarity of HCl to be 1M, you can compute how many moles of HCl you have at 25mL. The formula Molarity = mole/volume in Liter, or mole = Molarity x Volume in liter. Further, based on your equation, you know you need a 2 HCL to 1 Mg ratio. So just figure out how many moles...
