Okay, I've got thirty problems to do for chemistry, and I've done like 20 of them, and I've literally been working on this since 12 in the afternoon. I've been reading and rereading the chapter, but chemistry doesn't really come easy to me. Biology is my specialty lol. So here are a few problems from the page... could you not only tell me the correct answer, but give me a little explanation as to why.... Your help would be MUCH appreciated. You don't have to answer all of them, just answering one would help me greatly lol.

For 1 and 2 the answer is either hybridization, resonance, or vanderwhaals forces.

Question 1: It is used to explain the fact that the four bonds in methane are equivalent...

Question 2: Its used to explane the fact that the carbon-to-carbon bonds in benzene, C6H6, are identical

Question 3: Which of the following does NOT behave as an electrolyte when it is dissolved in water?

A. CH3OH
B. K2CO3
C. NH4Br
D. HI
E. CH3COONa

Was God thinking to himself when he said "let there be light" or did he actually say it to be heard? Which one enhances the other and in which order did it occur? Is there a measure of equivelence to sound verses light? In the beginings of creation, was there a sound that became as light was projected as witness upon the initial happening of something new? Was it simultaneios?

Jennifer bought a brand new sports car. The price of the car was 14, 900 including sport wheels, an AM/FM CD stereo, and automatic transmission. The dealer gave her a $1,250 instant rebate on the price and 0% interest for 60 month. Jennifer made a down payment of $750. What would be the expression for Jennifer's monthly payments if she takes 60 months to pay the remaining balance?

(14900+750+1250) / 60
14900/(750+1250 * 60)
(14900/-(750 + 1250)) / 60
(14900-750-1250)*60
14900+(750-1250)/60

If it was round, then it would just roll away! I mean, this is common sense. Plus all the people in the "Southern Hemisphere" would fall off the bottom.

The government has created this "round earth" lie to hide the fact that millions of innocent people have fallen off the edge!
