    Chem 2, Cell diagrams for oxidation/reduction reactions

    Oh yeah I forgot about that. So using the table and the diagnoal rule the correct equation is: Al+Cu+2--->Al+3 +Cu But this leads me to another question. When I find the standard EMF of the cell using E cathode minus E anode (E Aluminum minus E Copper) I get a negative number, meaning the...

    Chem 2, Cell diagrams for oxidation/reduction reactions

    Homework Statement All I'm trying to do is translate the cell diagram below into a into a an equation so I can determine which is the anode and which is the cathode. Here is the cell diagram. I know how to balance it, I just want to make sure I'm putting reactants and products on their...

    Medical Some questions about action potentials

    That equation is a bit past my level of comprehension at this point, but it's nice to at least know the factors involved.

    Medical Some questions about action potentials

    My question arises from study during my Human A+P class, but it goes beyond what I'd be expected to know for the class so I decided to post it here. When potassium exits the cell body during repolarization, is this due to its concentration gradient? If so, why does the chemical gradient get...

    Chemistry How Do You Calculate Kp for the Formation of Ammonia from Nitrogen and Hydrogen?

    Homework Statement The standard Gibb's free energy for the reaction N2+3H2<--->2NH3 is -33.0 KJ at 298 K. Everything is a gas. Calculate Kp for this reaction. Homework Equations I have in my notes that Keq=e^(-Delta G/RT) where R is the constant 0.008314 KJ/K. I also have a formula...

    Longer Digestive tracts not suited for meat consumption?

    I was talking to a vegitarian friend who claimed that because humans have relatively long digestive tracts meat consumption may be harmful to us. Upon further investigation she didn't have any real science to back this up. As far as I know the main potential problems with meat are the...

    Chemistry Chem 2: # of pi bonds in a molecule

    I finally just decided to ask my teacher. Your method does yield the correct answer but it shows a greater depth of understanding than we're required to have at this point. It turns out that formula just means six multiplied by the number of atoms that can potentially form pi bonds plus two...

    Chemistry Chem 2: # of pi bonds in a molecule

    Thanks for the reply. But I'm almost positive there is a quicker way to do it using that formula. This would be one of many questions on a one hour test and drawing the lewis structure for something that big would take me forever. One thing to add for clarification is I think technically that...

    Chemistry Chem 2: # of pi bonds in a molecule

    Homework Statement How many pi bonds are in the molecule C12H18? Homework Equations I have in my notes the formula (6nPi+2-total # of electrons)/2. The Attempt at a Solution Unfortunately I can't find an explination for this formula in the book and I don't remember what was...

    How does water toxicity occur in extreme situations?

    My teacher used a couple examples of real life water intoxication and his description of these evensts left me a little confused. One event he mentioned was a marathon on a cloudy, cold day where the runners were drinking despite the fact that they weren't sweating. My understanding was...

    Question about composing functions

    Thanks Jon that makes sense. So the first step is to realize that an opposite value of X on the inside odd function will yield an opposite value for that whole function G(X), then mentally replace -G(X) with -X and remember that for an even function F(-X)=F(X). That is so cool.

    Question about composing functions

    In an even function all points are reflected across the Y axis. In other words for every point (X,Y) there is a corresponding point (-X,Y). The value of Y does not change when X is replaced by -X, i.e. F(-x)= F(X) An odd function has an opposite value for Y when X is replaced by -x, i.e...

    Question about composing functions

    I am trying to give an explination or proof as to why F(G(X)) is always an even function if F(X) is even and G(X) is either even or odd. I understand why in simple situations such as when the resulting function is (X^3)^2 or (X^2)^2. It's because the product of two even numbers OR an odd...

    Does symptomatic relief slow recovery?

    I know that for many bacterial infections that cause diarrhea such as E. coli, treatment of this symptom is not recommended because it impedes the bodies ability to expel the bacteria. In the case of Clostridium difficile infection it can even increase the liklihood of dangerous complications...

    West Nile Virus, the blood brain barrier and the elderly

    When you say brain endothelial cells are you referring to the cells of the BBB? I don't know a lot of terminology, all I've had is one semester of biology and am currently taking micro. If you are referring to the BBB, I have not read of WNV actually infecting endothelial cells. It mainly...
