Chem I: Determining Acidic, Basic or Neutral Salt
See... I don't understand how this works. Haha. I got one at least! My prof went through all this a little too fast for me. Any online resources to help me better understand this? (I like to be active with learning, not a whiner who just wants the answers)- markelmarcel

Chemistry: Prediction of producs
Ok I'm still working on balancing but for the second I'm assuming the insoluble salt has to be Sr3(PO4)2 Because PO4 is insoluble, as is Sr (with it being a group II cation).- markelmarcel

Chem I: Determining Acidic, Basic or Neutral Salt
Homework Statement Predict if the following salts are acidic, basic, neutral or undetermined. Homework Equations a. NaOCl b. NH4I c. Sr(ClO3)2 d. KCN The Attempt at a Solution A. NaClO = Na+ and ClO- So, if Na+ gives up a proton, that would turn it into Na... and...- markelmarcel

Chemistry: Prediction of producs
Ok so for the first one I got... NaNO3 + 3(NH4)2SO4 + 2Fe(CH3CO2)3 \rightarrow Fe2(SO4)3 [/SUB](s) + 6NH4CH3CO2 When I looked up what I had for my solubility rules I found Na3PO4, RbClO3 and Sr(NO3)[SUB]2 to all be soluble... So where do I go from here? Randomly place things together??- markelmarcel

How to Calculate the atomic mass of this isotope?
so 1 mol would equal whatever the atomic mass of this isotope is... you're given a sample of the isotope... think about how you would set up an equation to solve for "x" (x, in this case being the atomic mass)- markelmarcel

General Biology - Faciliated Diffusion
Ok. I think I've got my whole answer now... "Simple diffusion and facilitated diffusion are both types of passive transport in cells. Simple diffusion takes place with nonpolar molecules that have no issues crossing through the hydrophobic center of the bilipid layer. However, not all...- markelmarcel

General Biology - Faciliated Diffusion
He defined saturable as being that you can only go so fast before you hit a maximum speed. The example he gave us was if he was standing at the door of our classroom and to get out of the classroom you had to shake his hand. First of all, you are required to have a hand for him to shake to get...- markelmarcel

Biology - Diffusion/Osmosis of 2 Solutions
Ok- or would water not be moving at all? Since a mol isn't really a number it would be the same thing as saying "a dozen" of something. So- if I have apples(Na), oranges(Cl) and pears(K) I could say... Solution A- has 1/2 dozen apples, 1/2 dozen pears and a dozen of Cl. Solution B - has 1...- markelmarcel

Biology - Diffusion/Osmosis of 2 Solutions
Ok. I was able to figure out Part A while I was waiting for a reply. It was actually a multiple choice question with instructions to choose the correct answer or answers. So the choices for Part A were: (my answers are bolded) A. K+ will diffuse from A to B B. Na+ will diffuse from A to B...- markelmarcel

Biology - Diffusion/Osmosis of 2 Solutions
Homework Statement You have two solutions - Solution A = 0.5 M NaCl and 0.5 M KCl Solution B= 1.0 M NaCl If Solution A and B are separated by a) a membrane permeable to all three ions what will happen? and b) a membrane that ions can not pass through but that water can, what will...- markelmarcel
