A sealed container of volume 0.10 m3 holds a sample of 3.0 x 10^24 atoms of helium gas in equilibrium. The distribution of speeds of helium atoms shows a peak at 1100 ms-1. Caluculate the temperature and pressure of the helium gas. (helium atom 4.0 amu) H...

Hi, I'm having trouble using implicit differentiation to determine dy/dx in the form dy/dx = f(x,y) for sin(2x+3y)=3x^3y^2+4 Do I make it sin(2x+3y)-3x^3y^2=4 then differentiate to get 2cos(2x+3y)-9x^2*2y=0 ? I'm a little lost... Any help appreciated.

You have solutions of 0.200 M HNO2 and 0.200 M KNO2 (Ka for HNO2 = 4.00  10-4). A buffer of pH 3.000 is needed. What volumes of HNO2 and KNO2 are required to make 1 liter of buffered solution?

Hi the question asks me to calculate the mass of calcium carbonate that must be decomposed to produce 14kg of calcium oxide. I think I've gone wrong somewhere, do you write 14000g or 14kg etc, could you help? I did: Moles CaO=(Mass CaO/Mr CaO) =1400/56 =2...

Thanks for the help drwls. I have now also found the average kinectic energy of the helium atoms. But what is the position of the maximum in the energy distribution? Is this the peak energy that I need to find?

Thanks for your reply. I tried again and got cos(2x+3y)*(2 + 3dy/dx = 9x^2y^2 + (6x^3*y dy/dx) Looking at your answer it seems wrong also. Should it not be 9y^2x^2... on the 1st part of the right hand side of your equation? Or am I missing something here?...

Awesome. Think I've done it! Cheers for the help.

Howw? How does it apply? I kinda forgot over spring break... How do you find the volume that you need?

Thanks for the help. I went with Ms. Sue's answer because she explained why the answer was what it was and she was correct. Thanks for the help!

Given that its really far away from the planet you can assume that PE = 0

Thank you so much!

Thank you so much for the help! Do you think you could expand a bit on the Left-hand approximation Right-hand approximation, Trapezoidal approximation, and Midpoint? Also, is there any way of doing part 2C without graphing? Again, thank you so much for us...

Yo, whats vibing y'all? I'm sure you all know it by now: CADCC are the answers. Just took the test, and my answers are set.

these teachers are so confusing and boring to listen to its killing us lol
