Homework Statement For the hydrogen atom in the first excited state, find the probability of finding the electron in a classically forbidden region. Homework Equations E1 = -Z2μe'4/2n2ħ2 ψ200 = ∫ψ(r)2dr from the limit to ∞ The Attempt at a Solution https://imgur.com/a/fWIMq I feel like this...

Homework Statement https://imgur.com/a/8deZc Homework Equations P(E) = ∫φ*(r)ψ(r)dr from -∞ to ∞ The Attempt at a Solution To find the probability, I know I have to use this equation: P(E) = ∫φ*(r)ψ(r)dr from -∞ to ∞ My question is, what is the energy eigenstate, φ*(r)? Is it the measured...

I did take a first semester Biochemistry course, but we never talked about what happens when amino acid sequences repeat. The question that I initially asked is really all that was asked in the homework I am doing for my Chemical Information System/Bioethics course.

The hits I see do not pertain to the question as whole.

Yes, it's for a bioethics type of class. What did you Google specifically? I found a study that was conducted that pointed out there was just advantages to repeated amino acid sequences...

If a protein contains a repetitive region, what might be assumed, and what should be done next to test the null hypothesis? Can anyone answer this with a reliable source they find?

Yes, I do. I just changed the bottom row of A to be the constants of the recursive formula given, but I kept the first 2 rows I stated the same. I verified and got the eigenvalues in b. I thought there was more than one matrix because in the equations, there are a combination of values for each...

So A can be more than 1 matrix?

Sorry, I completely forgot that A was a 3x3 matrix. Anyways, I see how you are getting the solutions. For equation 2, I found these solutions: A21 = 0 A22 =0 A23= 1 For equation 3, I found: A31 = 0 A32 = 1 A33 =3 Are those correct? Does what they give for xk+3 have anything to do with the last...

Homework Statement Homework Equations a) the one given b) det(A-λI) = 0 find λ values using A c)use λ values to find eigenvectors The Attempt at a Solution This wasn't explained well enough so I can understand it in class. So far, I made the matrix being multiplied to A have the following...

Homework Statement Homework Equations Henderson-Hasselbalch Equation The Attempt at a Solution Sorry for the huge picture, but the number says 0.007558 mol. Is my ICE table correct? Equation: 7.42 = 6.85 + log((0.007558-x)/x) (0.007558-x)/x = 3.715 x = 0.00160 mol H+/(0.07483 L + 0.01339 L)...

Thank you so much! I can't believe I didn't catch that. I finally got it correct. Thank you!

I think I forgot my algebra skills because I got it wrong again... Okay I tried what you did. I used the mass balance equation of post 3, plugged that into the Ka equation for [HCN], then I simplified more so I get Ka = 0.0871*2*([Zn2+]/[CN-]). I made the Ksp equation equal to [Zn2+], I plugged...

I got [CN-] = 4.81 x 10-7, [Zn2+] = 0.00130, and [HCN] = 0.00259 and it is still incorrect...

Okay so far, I made the mass balance equation and Ksp equation equal to each other by isolating [Zn2+], and I solved for [HCN]. Can I just plug that back into the Ka equation, then solve for [CN-] this way? Also, [OH-] would be 1.15 x 10^-13 M, correct?
