this question is as it is,not metric conversions,6.1/4 gallons of water at 65 fahrenheit=1 cubic foot,i say 65 fahrenheit as if the temperature was higher the water would expand,...liquid propane gas stays liquid only under pressure,normal propane gas bottles hold a pressure of about 80 psi,if this pressure altered to 50 psi,would this mean the gas would expand...what do you think.

(-2√a - 2√b)(-2√a + 2√b)

What rules apply here? Besides foiling how do you combine the like terms, this is just an example, not sure if it works out!

problems such as---
1. 689.3 grams of aluminum sulfate (moles)
2. 4.69 X 10^25 atoms of gold (moles)
3. 1.50 moles of calcium chloride (grams)
4. 1.26 X 10^24 formula units of sodium phosphate (grams)
5. 2.57 moles of potassium nitrate (particles)
6. 42.8 grams of magnesium sulfate (particles)

i'm fine on finding the molecular mass, i don't understand how to use dimensional (sp?) analysis to take that and find out what the answer needs to be in parenthesis.

For example, imagine that a container was covered with a cover that is not see through. Would the same amount of heat still be able to escape, or would it be less? Why?

String theory predicts all material in the galaxy from the smallest subatomic particle to the grandest star is made of strings. The string vibrate like music note giving atoms their uniqueness. Most physicist don't accept this theory since their are five formulas. The formulas are quite similar. Is it possible this five formula represent five equally similar worlds us ours; but except for a small insignificant difference like a parallel world.
