Hello,
I wanted to know if connecting a battery in series with a voltaic cell would increase the rate of the redox reactions.
Let's take the simplest example of a voltaic cell constituted by a Zn/Zn2+ half-cell connected to a Cu/Cu2+ half-cell. When the circuit is closed, the Zn electrode will...
Sorry for the late reply, but my question was not how to draw the MO of NO. I wanted to know which one would be identified as HOMO and which as LUMO, considering that there's only 1 electron on the highest level but there's also a free orbital next to it
Hello,
as the title says, how do you treat singly occupied orbitals in radical molecules, when trying to identify the HOMO and LUMOs?
In the majority of cases I stumbled upon, like O2, both the antibonding orbitals, pi*2px pi*2py, are singly occupied, so they would be considered the HOMO, with...
Hello,
I was toying around with shapes and dies and wanted to calculate the load distribution in all spots so to get a rough idea of the maximum load I can use before breaking the die. The "problem" is as follows: I have a die shaped like a trapezium and I have to press an item (5-10mm thick)...
I'll go step by step to make sure I'm not missing anything and also because this is the first time I use LaTex, so that it is easier for you to point out my mistakes.
The relationship for pressure, pipe length and velocity is:
$$\frac{dP}{dx} = \frac{ρfv^2}{2D}$$
ρ and v are affected by...
Wow, that's a really nice source of Information, thank you very much. My upcoming question would have been "how do I get an equivalent length of the pipe", but the first link addresses it and also so many options to play with.
Thank you again, this is very helpful! I will take my time to come...
There is a heating element in that chamber that, after a certain pressure is reached, will start heating to the desired temperature. Once that temperature is reached, we open the valve so that air is sucked in the chamber because of the pressure difference from inside and outside of the chamber...
Unfortunately fluid dynamics is not my field of expertise. I've learned the basics back in my 3rd year of university and that was it, so now I'm relying on 6 year old knowledge of something I've never really practiced and that wasn't the focus of my studies. I am unsure if I am even approaching...
Hello,
I'm a chemist and I'm currently working on my PhD on materials science.
I'm trying to determine the pressure difference necessary to achieve the desired gas flow inside a chamber. The scheme of the chamber is the following:
I have a big chamber which is evacuated to 0.2 bar, and another...
