the equation is (Zigma ((-1)^k.n!.2x^2m-k)/k!(m-2k)!)from 0 to M
that M=m/2 or M=m-1/2
we solve the the differential equation(hermit) but how we can access to this complete formula.please write the all details.

Pretend you are drawing cards without replacement from the infamous "Iraq's Most Wanted" deck issued by the U.S. Military before Saddam Hussein and his gang were killed or captured.

If you are drawing from the full deck of 52 cards (no jokers), what are the following probabilities:

a. You draw a card that is not Saddam Hussein

b. You draw three cards, which end up being Saddam Hussein and his two sons (whose pictures were also in the deck of cards.)

c. You draw 13 cards and not one of them is Saddam Hussein

I just overheard a story a woman just told about squirrels eating the pedals of her bicycle. I think this is BS...but maybe I'm wrong, since I don't know much about squirrels. So nature people: what do you think?

I know that the answer is x4 + 9y, but I just don't understand why. Can anyone explain the steps to me?

(by the way, the x's in the question are raised to the value of 2. and the x in the answer is similarly raised to the power of 4.

I have a huge end of semester test and i need help understanding hybridization and answering some of these questions. anything helps...thanks.


1.SO2-
Why doesn't his create a double bond?

2.How do you know polarities based on the shape of a molecule or bond?

3.NO2-
Why is this hybridized as sp2 shouldn't it be sp since it has two unpaired electrons

4. NH3
why is this hybridized as sp3 shouldn't it be sp since it has 2 unpaired electrons

5. how do you draw out hybridizations

6. what factor determines the shape of a molecule

7. Can a molecule be polar w/o polar bonds w/ in the molecule

8. Can a molecule with polar bonds be nonpolar

9. How do you know whether a molecule or bond is paramagnetic or diamagnetic
