Describe the difference between the following and list any particular advantage possessed by one over the other a)filters and monochromators as wavelength selectors
Why do oxyacids become stronger when more oxygens are added. (as in the case of HNO2 being much weaker than HNO3)
Assuming that all the other quantum numbers can take only the values possible in our world and that the Pauli esclusion principle applies, give the following.
