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)
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).
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...
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??
Homework Statement
Predict products (and then write formula unit, total ionic unit & net ionic equations)1. Sodium Nitrate, Ammonium sulfate and Iron (III) acetate.
2. Na3PO4 + RbClO3 + Sr(NO3)2
Homework Equations

Homework Statement
Explain why carohydrates are found attached to integral membrane proteins on the outside, but almost never on the inside (cytoplasmic face) of cell membranes.

Carbohydrates bond with integral membrane proteins on the...
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)
Homework Statement
(Last one!) I think I filled out this table correctly, I just want someone to check over it for me, if you would :)
Oxygen enters cells by simple diffusion, glucose enters most cells by carrier assisted (facilitated) diffusion, the sodium/potassium pump removes sodium...
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...
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...
Homework Statement
Explain why facilitated diffusion, unlike simple diffusion, is both specific and saturable.

Is this a good beginning to an answer? I feel like I can never...
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...
