Hello! 🙂 I should understand the diagrams for these problems (a) and b). I also have the solutions. (See the second image opposite.) However, I'm not quite sure what the diagrams mean. Could someone explain the process to me and describe in detail how they were arrived at?

Loading...Why H2SO4+H2O <-> H4O+ + HSO4-? And not H4O+ +SO4-? (The numbers belong further down and + & – further up)
Hello everyone, Nitrogen can have oxidation numbers from -III to V. I know that the V is determined by the electron configuration of nitrogen, meaning it can only hold a maximum of 5 valence electrons. However, I'm confused about how to explain the minus-III. Do I just have to memorize it, or is there some…
Good day or evening my question is: Describe the processes in Fehling's test using the example of a compound of your choice with a reaction equation and partial electron equations. I haven't covered this topic in class yet and I don't know how to approach it. Can anyone help? Thank you very much in advance!
I have lead sulfide and want to separate the two substances. I want to get both back at the end. Besides, I only have what I normally have at home. How do I do that?
100 ml of hydrochloric acid (c=1 mol/l) is neutralized with 200 ml of sodium hydroxide solution (c=0.5 mol/l). The heat of neutralization is -56 kJ/mol. How high is the temperature rise? Need urgent help
How do you generate single photons?
Hopefully you know what the wave functions look like (only radial parts, unnored, in atomic units):
1s: ψ(r)=e ̄r
2s: ψ(r)=(2-r)e ̄2rᐟ2
2p: ψ(r)=r⋅e ̄rᐟ2
3s: ψ(r)=(27-18r+2r2)e ̄rᐟ3
3p: ψ(r)=(6-r)e ̄rᐟ3
3d: ψ(r)=r2⋅e ̄rᐟ3
And these are simply the functions that are plotted in the first row. In the second, you have the radial densities, i.e. the square of these times r2. The maxima in the densities correspond to the distances in which the electron is most common.
Thank you.
