what is the boiling point of water at 475torr?(Tb=100c R=8.3145j/k mol)
2.Rank the following compounds according to increasing values(disorder) of ΔS
°soln(JK^-1mol^-1) for LiF NaCl KCl and CaS dissolvin in water
3.which of the following molecules display optical activity?
trans-[Cr(en)2Br2]- cis-[Cr(en)2Br2]- [Co(edta)]-
[Co(en)3]3+ cis-[Pt(NH3)2Cl2] [CrCl2Br2]2-(tetrahedral)
4.the compound ZrI4 can be mdescribed as cubic cloest packed anions(I-) with
the cation(Zr4+)in tetrahedral holes.
what fraction of the tetrahedral holes is occupied?
(A)1 (B)1/2(C)1/4 (D)1/8 (E)1/16
請各位幫個忙,實在想不出來,快要考試了,覺得有完蛋的感覺
