Homework Statement
For instance I have NaCl. I found a relationship between conductivity of NaCl in water and concentration of NaCl in the water. It's; conductivity is approx 0.5 concentration
Is it correct that the change in concentration gives the number of ions?
For example say I...
1. Hi, basically I'm trying to find an equation to find ion specific molar conductivity of salt water flowing between electrodes.
Homework Equations
resistivity: rho = RA/L
conductivity: kappa = 1/rho
conducitivity per unit concentration: lambda = conductivity/concentration
this is ion...
I tried, here's the code but no luck!
Also something really annoying has happened now... some of my images don't appear till the end of the document even though there's room for the images where I set them to and using [h!] doesn't put them where I inserted them... gah!
Hello,
I'm just wondering is it possible to put the units of a parameter underneath it rather than next to it. My table is pretty long and I could free up space if I could do this.
For example, let's say I have Velocity (m/s)
I want it to have (m/s) below velocity
I can't figure out how to...
I did it already using integration by parts. First time I did it didn't yield something similar to the hint I was given. Had to do integration by parts twice and the exponential was still divided by ao all the way through.
1. Relevant problem
integrate from 0 to infinity of r^2exp^(-r/a0)dr
Homework Equations
I'm also given; integral from 0 to infinity of x^nexp^-x dx = n!

I'm just wondering if I can split up the exponential to make it look like this form. Eg;
integrate from 0 to...
Ah ok, thanks for clearing that up. The number of nearest neighbours is 8, is the number of second nearest neighbours 6? As the four cl atoms at the corner of each face are bonded to a cs atom?
Oh yeah, I know that. But why don't they call it bcc when it looks like a bcc structure and why does it changed from simple cubic to bcc when its 2 caesium?
Hello, I'm really confused by something.
Cscl is simple cubic. But how it this possible? With the cl in the middle it looks like a bcc structure. Also howcome when you have 2 caesium its bcc and not simple cubic? its the same structure yet it changes to bcc. Is it because they are both atoms...
Ah wait, I realized that I needed to add another 70% onto the 300 MW which gave me 1,000 MW. However the answer I got was 834.98 Kg, seems pretty high to be correct. Am I doing something wrong?
