How much energy in kJ/mol is required to remove electron fromthe following orbitals in an H atom:

4d, 4f, 4p, and 4s.

I think this has to do with the ionization energies but am i not sure. Please help.

Water undergoes a large change in density at 0 ∘ c as it freezes to form ice. calculate the percent change in density that occurs when liquid water freezes to ice at 0 ∘ c given that

What is the rate law for the uncatalyzed reaction?

The bohr model of the atom explained why emission spectra are discrete. it could also be used to explain the photoelectric effect. which is a correct explanation of the photoelectric effect according to the model?
