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...
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.
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.
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.
[SOLVED] Electronegativity Confusion
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...
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...
[SOLVED] Percent of solution
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...
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.
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.
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...
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...
