Science & Mathematics - 3 September 2007

My assignment is to find chemical additives in normal household products and to determine the structual and functional nature of each chemical and why the compund might be added to the product. These are the products I picked....
Toaster Pastries...Sodium Bicarbonate
Spaghettioes...Ferrous Sulfate
Marshmallows...Tetrasodium Pyrophosphate
Tylenol...Acetaminophen
Pain Relever...Naproxen
Lotion...Stearic Acid
Foundation...Iron Oxide
Hand Soap...Sodium Chloride
Stain and Odor Remover...Isoprophyl
Glass Cleaner...Ammonia
Raid...Tetramethrin

I think I did it wrong. For example, for Na4P2O7 (marshmallow) , i wrote that its used as a bufferinf agent, an emulsifier, and a thickening agent and is often used as a food additive. I think that I am supposed to say exactly what reacts with what or bonds with what to do this etc. Do you have any idea how to answer for any of the compounds i listed? I dont! PLease help!

O.k. I know that like gravity is when two molecules like attract to each other. And the more the mass, the more gravity. But what is gravity? Like what causes it? I'm just real puzzled here. Somebody help me!

Please help me solve this problem.
A manufacturer has a monthly fixed cost of $40,000 and a production cost of $9 for each unit produced. The product sells for $16 per unit. If the manufacturer produces and sells 3000 units per month, indicate whether he will have a profit, loss or break-even.

Why couldn't alien space ships be as large as the moon, or as small as a speck of dust? Would there be any scientific reason why not?

and does anyone else belive that arguing about religion and real estate is pointless, and that we should be furthering MANKIND - colinizing new planets- finding alien races, (I mean, personlly, I want to really fing other world that are habitable for humans, and learn new sciences and make the impossible possible... I want to see this world move beyond dead plants and animals for our main energy sources. I want scientists and physistist and doctors to be our heros. I want to progress into something more and not waste time with individual, insignificant personal opinions and making any one else conform to our "RIGHT" way of thinking? Anyone else out there want this kind of progression? ANyone else other look at the sky and see the beautiful blue, and then want to see that dark space above our atmosphere, and not feel so unfamilar about it?( I really mean this question not for the "dreamy artsy types"-but for those that want to see it as a reality, and what their thoughts are about it)

I just want a decent conceptual explanation of the theorems, I've read through some books and received a technical explanation, but my professor doesn't explain things so well imho, so I'm just looking for more of a "dumbed down" explanation. I think I'm starting to get the idea, but I don't quite fully grasp it yet. I'm hoping that your explanations might help me get there. Thanks! :)

I've often thought that we are inside something larger. We could very well be the building blocks of a atom in a much larger universe where a billions of years would be only a second. Time is relevant to size and I really think that if you keep cutting something in half when would you have nothing. You'd eventually get so small that you couldn't even see it or detect it but something would be there. I think this is a never ending chain and it really doesn't matter where we fit in because it goes on forever both ways. There are probably even universes inside of our bodies inside the very atoms that makes up our minds. I don't hear much people speculating on this because I think people want to think they are more important than that but I just want the truth which I will never get but I'd like to get some other people's take on this.
