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.- MichaelXY

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...- MichaelXY

VSEPR Model for AsH3 and OF2: Understanding Molecular Geometry
Eli is correct. I am sorry for my misinformation. http://en.wikipedia.org/wiki/Oxygen_difluoride By the way, What book are you using?- MichaelXY

VSEPR Model for AsH3 and OF2: Understanding Molecular Geometry
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.- MichaelXY

Determine Color of Solutions: Co(NO3)2, KMnO4, Na2Cr2O7, ZnCl2
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.- MichaelXY

Why Does Electronegativity Decrease Down a Group?
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.- MichaelXY

Why Does Electronegativity Decrease Down a Group?
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- MichaelXY

Why Does Electronegativity Decrease Down a Group?
[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...- MichaelXY

Calculating Glucose Concentration 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?- MichaelXY

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.- MichaelXY

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