I have tried about a million ways to figure this problem and just don't know how. My professor told us to teach ourselves from the book but the book does not cover this type of problem or it is going over my head. Please explain how to solve it. Don't just give an answer I need to know how to do it for a test.



Nitroglycerin (227.1 g/mole) decomposes according to the reaction below.


4 C3H5N3O9(Liquid) yields 6 N2(gas) + 12 CO2(gas) + 10 H20(g) +O2(gas)

What total volume of gases is produced at 65 degrees C and 744 mm Hg by the decomposition of 5.00g nitroglycerin? (R=0.08206 L atm/mol k)

If I get power from a battery and utilize the aid of a series of capacitors and use it to run an electric motor will the cost for maintaining the battery(recharging) be cheaper than utilizing electric current, gas or diesel? Will aligning the capacitors in series not affect the performance of the motor and what are the possible problems that may arise if I use it for a maximum of ten hours? How long will the battery last and the capacitors? What is the limit of force of the correct set set up? Can this be considered as an energy saving concept?

I've always wondered why human babies dont have the common sense to try to refrain themselves from jumping or falling off the couch or any other high place.It seems like any other baby animal like kittens or puppies seem to have the basic instinct and or common sense not to attempt it.It seems like they want to but have the ability to know its going to hurt them if they do.It also they seems like their afraid to.

I need the wisdom of a person who knows about facial features. I believe that everything has a name because my dictionary has 2077 pages. There is something rare I love but I need to put a name on it. It is that little groove on the tip of someone's nose. I am not talking about the philtrum below the nose which is the vertical groove on the upper lip between the nose and the lips, I am talking about the groove at the tip of the nose, between the two nostrils. I think it is the cutest thing ever. If I would like feet, I would be a foot fetishist but I like that so what am I? Incidentally, the actor Johnny Depp has it and I believe that is one of the reasons he's so popular. I just want to know what the thing I think is the cutest is called.
