Consider the expansion of methane from 300 bars to 50 bars at a constant temperature of 40 C (313 K).
Methane obeys the following equation of state
V =(RT/P)+C+(D/T)
where C = 31 cm3/mol, D = -693cm3K/mole, and R = 83.14bar cm3/mole K. Note that the units of
energy are bar-cm3/mole in this problem. Report your answer in bar-cm3/mole
(a) What is the change in enthalpy during the expansion
(b) What is the change in internal energy?
(c) What is the heat removed?
(d) How much work does the system do during the expansion?

and in the decimal system. How many digits are there in these two numbers all together?
C.1379. Alex and Burt took their rabbits to a whole salesman to sell them to him at once. Each of them got as many dollars for each of their rabbits as many as the rabbits they each took to him. But, because their rabbits were so beautiful, they each got as many extra dollars for their rabbits from the salesman as many as the rabbits they each sold him. This way Alex received $202 more than Burt. How many rabbits did they each sell to the salesman?
C.1380. How many {a, b, c} sets are there containing three positive whole elements, where the product of a, b, and c is 2310?

Based on the energies you found in c and d, which of these complexes has the largest predicted splitting between the t2g orbitals and the eg orbital. Remember--not every element has occupied d-orbitals. How is that going to impact your next answers?
Which one would absorb the longer wavelength of light? Explain why.
Transition metal complexes are often vibrantly colored due to the splitting of the d-orbitals caused by the ligands. Based on your results would you expect that both of these complexes have any significant color? Explain.

8.Hi there, I've been struggling with the problem for quite a while and i have not been able to find ...

formula online to help.. It should be a simple straightforward problem but i just can not for the life of me figure it out. are you able to provide me with a formula or point me in the right direction?
The problem is:
Solution A has a 50% concentration
Solution B has a 100% concentration
Solution C has a 5% concentration
you have 5L of each solution to utilize as well as unlimited quantities of water to dilute solution concentrations if needed.
Part A
Make a final solution of 100ml with solution concentrations of Solution A 15%, solution C 5% and solution C 80%. how much of each solution will you need to make your final 100ml solution?
Part B
using the above solutions how many 100ml final solutions can you produce with the 5L volumes?
No matter how I work it i can't make the solution to the correct concentrations.
Thank you for your help.
John

“A history lecture hall class has 15 students. There is a 15% absentee rate per class meeting. Find the probability that exactly one student will be absent from class.”
I already know that:
n = 15
p = 15%
q = 1 - 15 = 1 - 0.15 = 0.85
...and then you do: p (x = 1) = C 15 & 1 and then...

ng the package. Packages above 50 pounds will not be shipped. You need to write a program in C that calculates the shipping charge.
The shipping rates are based on per 500 miles shipped. They are not pro-rated, i.e., 600 miles is the same rate as 900 miles or 1000 miles.
Here are the shipping charges -
Package Weight Rate per 500 miles shipped
Less than or equal to 10 pounds $3.00
More than 10 pounds but less than or equal to 50 pounds $5.00
If the shipping distance is more than 1000 miles, there is an additional charge of $10 per package shipped.
