Ms.Sue is 9/10 a possible teacher. As a teacher she could probably tell that this student doesn't need any help with the work. Just wanted the answers not any help. There are teachers on this site you know. If these students keep up this cheating this site could get close...

I think the answer is B. Is that correct?

chemistry
A certain first order reaction has a rate constant of 3.75x10^-2 s^-1 at 25.0C. What is the value of k at 70.0C when the activation energy is 135 kj/mol? Would I use the formula K=Ae ^-Ea/RT even though I have two temperatures?

CHEM HELP!
Thank you for taking the time to answer me on this. I used the gaw law to solve for NH3 for the mass of it to then add it to the mass of H2S to find NH4HS. I think Im still a little confused on how to go about this, but hopefully by your answer I can figure it out.

CHEM HELP!
I plugged in the values P is pressure I have for NH3 which is 2.78, 5L for V, n, R the gas constant and T 298K. to get .5684 mol to .03388 g of NH3

CHEM HELP!
after using the ideal gas law to find moles then mass of NH3 to add to the H2S I got a answer of 3.0334g This is my last attempt to enter in a answer for the program I am using and I dont want to lose points, obviously. I just want to see if anyone can check to make sure I am ...

CHEM HELP!
NH4HS<-->NH3+H2S What is the minimum mass of NH4HS that must be added to the 5.00-L flask when charged with the 0.300g of pure H2S, at 25C to achieve equilibrium?? Kp=.120 at 25C initial pressure of H2S in flask = .0431atm partial pressures of H2S and NH3 .326, .369 mole...
