Here are 5 questions to try. I will give you 1 point per correct answer you provide to me by Tuesday 4/27/2010 2PM and no later. It will go directly to exam 3. You MUST send me the answers to my email here. I will post the correct answers after the due date and will not give hints or help.
#1 Define Electronegatity
#2 Give me the geometry using VSEPR model for CCl4
#3 Which of these structures is nonpolar and why? CS2, H2O, NH3, HBr, or CHCl3 You must have a good understanding of structure to get the correct answer.
#4 C3H8 + 5 O2 = 3 CO2 + 4 H2O True or False and why either way
3 grams of CO2 are formed per 5 grams of oxygen consumed.
