Document Summary
Answer all twelve questions with a few sentences or equations (5 marks each). The pauli exclusion principle states that no two electrons in an atom can have the same four quantum numbers. Beginning with nis(s), show the reactions leading to acid rain, i. e. h2so4(aq). Nis(s) + 1. 5 o2(g) nio(s) + so2(g) D e = q + w. in this case, both q and w are positive, therefore d e is also positive. The only difference is the size of the cation. The rb+ ion is smaller than the cs+ ion. Therefore the rb+ is closer to the br- than is the cs+, resulting in a larger force of attraction between rb + and br-, thus the larger lattice energy of rbbr. Thus, photons of almost any energy in the visible portion of the spectrum are easily absorbed, exciting electrons from the homo to the lumo.
