<em>Isn't that going to be an D since 1 foot is equal 12 inches.</em>
<span>Its D :) evaporation happens all the time, and can only occur at the surface (molecules break off and become gases) whereas boiling is when ANY molecule, whether from the surface, the middle or the bottom can just fly off and become a gas.</span>
It is an ideal gas therefore we can use the ideal gas equation to solve the problem. The ideal gas equation is expressed as PV = nRT. First, we solve the amount of the gas in moles using the said equation and the first conditions.
(2.0 atm) (5.0 x 10^3 cm^3) = n (82.0575 atm.cm^3/mol.K)(215 K)
n=0.5668 mol
Using the second conditions given, we obtain the new pressure.
P (4.0 x 10^3) = 0.5668 x <span>82.0575 x 265
P= 3.08 atm</span>
Answer:
I don't think you can go on without doing a reaction since you touch really anything so no you can not go without any chemical reaction I think this is the answer
Answer:
The values of n, p and q are 314, 0.12 and 0.88 respectively.
Explanation:
n is the number of subjects given a placebo. The value of n is 314.
p is the sample proportion of the subjects given a placebo that developed headaches. The value of is 12% = 0.12
q is the sample proportion of the subjects given a placebo that did not develop headaches. The value of q = 1 - p = 1 - 0.12 = 0.88
