I have the phase diagram below as an exercise. In this task, I'm supposed to calculate the phase fractions of alpha and S. However, only the temperature is given. Do I have to assume that I have to calculate the proportions at 0% and 800*C? That would be a=0 and b=5 So for alpha b/a+b=5/5=1…
How many electrons are released during ion formation?
Hello, I just saw that we have to represent the reaction between lithium and sulfur in the shell model. I then looked online and the reaction equation would be 2 Li + S = Li2S. I was given the first part to draw, but not the rest, so I didn't know how to draw lotium…
Hello everyone, I have a somewhat specific question: I ordered a so-called “displate metal poster”, which is basically a picture made of metal. It came with a cleaning cloth soaked in "Isoprypol Alcohol." I naturally assumed the cloth was there to remove fingerprints from the picture, for example, after hanging it up. But that's not…
