1)Order the hardness of the compounds NaBr, NaF, NaCl, NaI, LiF.
2)A thermally activated process (a reaction) takes four minutes at 848oC. How long will it take (in minutes) at 700oC if the activation energy is 150 kJ/mol?
3)Use formal charges and the Lewis dot method to determine the most stable structure for nitrous oxide. Nitrous oxide contains two atoms of nitrogen and one atom of oxygen. Answer the following questions about the most stable structure.
How many non-bonding electrons are on oxygen?
(is it six)??

edX is great right? I see you are enjoying MITx: 3.091x Introduction to Solid State Chemistry. Also notice how this are not problem sets, but a freacking Exam! The first page clearly stated what you can and cannot do. 
Does "You are expected, more than ever, to abide by the honor code while doing so."  mean anything  to you?
You are the reason why MOOCS will never fully develop. I hope they kick you out, or at least that you fail. : )

Without solving this question, my score can reach 60% and higher then  I can get honor code certificate. But that is easier to get information as the questions require research that I can't do now.
