14.12 (a) Here we should consider the Lewis structures: Br O _ Br O _ O Br O _ O single bond resonance structures give a bond order of 1.5 We expect the Br - O bond in Br - O - to be longer because it is a single bond, whereas the Br - O bond order in BrO 2 - is 1.5 and the bond should be shorter. One could also predict the Br - O bond distance in BrO 2 - to be shorter because the Br atom is in a higher oxidation state. (b) Si-H in SiH 4 . The radius of silicon is larger than the radius of carbon. 14.20 (a) HNO 3 (b) H 3 PO 4 (c) H 2 SeO 4 14.22 (a) 2 2 NaH(s) H O(l) NaOH(aq) H (g) + + (b) 800 C, Ni 4 2 2 CH (g) H O(g) CO(g) 3 H (g) + → + o (c) ,pressure, Ni 2 2 2 3 3 H C CH (g) H (g) CH CH (g) = + → The oxidation number of 2 2 C in H C CH is 2, and 3 = - - in H 3 C - CH 3 .

(b) The difficulty is isolating the two half cells but still maintaining electrical contact. Ions need to flow through the system to maintain charge

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
