Okay so i wrote the balanced equation, and thats pretty much all i can do.. if someone can help me that would be so great.. thanks !

CH3C6H13(l) + O2(g) --> 5CO2(g) + 8H2O(l)

Write a balanced equation for the combustion of CH3C6H13(l) (methyl hexane)
-- i.e. its reaction with O2(g) forming the products CO2(g) and H2O(l).

Given the following standard heats of formation:

* deltaHf° of CO2(g) is -393.5 kJ/mol
* deltaHf° of H2O(l) is -286 kJ/mol
* deltaHf° of CH3C6H13(l) is -173.0 kJ/mol


What is the standard heat of reaction (deltaH°) for the combustion reaction of CH3C6H13(l)?

The next question is

Calculate the difference, deltaH-deltaE=delta(PV) for the combustion reaction of 1 mole of methyl hexane.
(Assume standard state conditions and 298 K for all reactants and products.)

The concept of Noah's ark as described in the Bible was literally impossible to have actually happened. Why do people still believe in it?

How about splitting it in half, and giving half to the republicans, and half to the dems? Cuz it seems that in our quest to be free, we have segregated ourselves, except that instead of just by skin color, we are now splitting into either the "fluffy clouds and flower smellers", or the "if you don't like it get outers". (I'm going to stay here with them incidentally)

It kind of seems that men take a lot longer to figure out that a specific girl is "the one." Women on the other hand, seem to figure that out right away.

I think that women are much more likely to experience love at first sight.

You know, when you see a person for the first time and realize, "Hey, if he and I were the only two people left on the planet, I probably wouldn't kill myself."

I thought he had some good points. That the early publishing of the Gospels gives them credit. That may have even been 30 years after his death. That even the oral tradition held back them was found to be extraordinarily accurate and of course kept by trained men who memorized the whole tor rah. That Jesus apostles who lived when Jesus was alive died for Jesus sake knowing they were not dying for a lie. More than one disciple died for this cause. The urgency of a Roman guard to keep his post and be alert to keep his post as the grave was guarded. Not to mention all the old testament scriptures Jesus fulfilled. Below follows a link to 365 prophecies fulfilled by Jesus. http://www.bibleprobe.com/300great.htm
or http://www.bibleprobe.com/365messianicprophecies.htm
the chances that Jesus would fulfill all these is mathematically silly. But it happened. The Fulfillment of the New Covenant Prophesied. Jeremiah 31:33-34, Hebrews 8:7-11
So did I leave anything out?

I'm a senior in high school and want to get into pharmacy school or do pre-pharmacy and then transfer to a pharmacy school but here's my question:
1. Some schools offer pharmacy as a program but not a major, does that mean that I still have to take up a major? If so, what major should I take if I want to be a pharmacist?
2. Anyone know of any good pharmacy school or schools that have pre-pharm in New York, New Jersey, around that area?

You have a large glass flask containing a small amount of acetone (boiling point = 56°C; freezing point = −95°C). The temperature of the flask is that of freezing water. What is the state of acetone in the flask?
