    Entropy changes for reactions: Understanding Periodic Trends

    Look, I don't want to step on anyones toes here. But, this is not a homework question. Questions that we pose arise from many different places. Is there an "I was talking to my friend and she said *blank* but I wondered about *something else*" section? No. And, you are right, these questions...

    Entropy changes for reactions: Understanding Periodic Trends

    ! This is NOT a homework question! I am floored that a conceptual question, that arose from homework, would be moved. Like I said, the book asks if there is a trend, and there is. I am asking WHY there is a trend. That is not part of the homework and this question should be back where I...

    Entropy changes for reactions: Understanding Periodic Trends

    One question posed in a general chem book I have were the trends of a couple of reaction types. They don't answer the question of why, though. Maybe you can help... Identify periodic trends of these rxns: Set 1: H2 + X2 --> 2HX (X are halogens) Ex: H2(g) + Cl2(g) --> 2HCL (g)...

    Recommend a fluid mechanics book

    How do you guys feel about Denn's Process Fluid Mechanics? It is being used in my next undergraduate course and it seems a bit small, should I be looking for a supplement? thx.

    Courses Chemical Engineering Student needs opinions on course usefulness please.

    Well, I know these questions have probably been asked before, but I really am having a tough time deciding which course to take. I linked the syllabus/course websites from previous semesters of these in hopes that people could take a look and say "oh, as a chemical engineer this looks...

    Courses Chemical Engineering Student needs opinions on course usefulness please.

    I can take one of the following 3 courses as a technical elective. I need to know which would be the most useful to me. My Math background: I have taken a year of Calculus, linear algebra, and diff eq (no partials.) Thermal Physics [text: Kittel "Thermal Physics"]...

    Linear Programming -OR- Engineering Economics?

    Thanks, guys. I have taken Macro Eco already, but it has been a while. I was not a huge fan, but I think this course will be more practical. I am also planning to take a math course to help me use the tools I have learned in practical problems. [Math for physical sciences]. -A

    Physical Chemistry: a Molecular Approach, McQuarrie

    To not run screaming from this course again next semester. I dropped it this semester because I just was not catching on. Suppose I was hoping to hear that a good complimentary text to this would be _ Insert name here _ . thanks. Angela

    Physical Chemistry: a Molecular Approach, McQuarrie

    Opinions on this one? Specifically for the QM uninitiated. If you have other recommendations for better clarity, please comment. Thx. A.

    Chemical Engineering: Advice from Those Who Have the Degree

    Ok, here goes... Why does this seem "right up your alley? Is it because you like chemistry? You like math? You like the idea of engineering something? I don't want to be discouraging but was in a similar predicament a while back and am currently a CHE major and not sure if it is for me...

    Force in a potential field V(x,y,z)

    Thanks! I will look into that, I remember gradients from a long time back, I was never terribly great with math and now it is all rusty. Much appreciated, -A

    Force in a potential field V(x,y,z)

    I have a problem that asks for force in the x-direction on a particle in a potential field given by some function V(x,y,z). The problem asks what the force in the x direction is if the particle starts resting at (1,2,3). I tried reviewing magnetism but found F = B x v where F and v are vectors...

    Recoil energy and Heisenberg Uncertainty principal

    "it is transmitted and absorbed by the electron , and if that disturbance is ramnant enough to provide the minimum possible energy for an electron to make a transition , it will ." Yes, I think I'm actually getting a little closer to solving this (after hours of trying..) I will update...

    Recoil energy and Heisenberg Uncertainty principal

    I need to prove that the act of measuring exactly the position of an electron would change its orbit. change in position x change in momentum = h the limit would suggest that knowing the location exactly would set the change in momentum p= h What is the formula that relates energy...
