In this Homework you will prove the Heisenberg Uncertainty principle for the n=1 state of the particle in a box model.
Find the expectation value of x for n=1 in a 1-d particle in the box with length L, and particle mass m.
Find the expectation value of x2 for n=1 in a 1-d particle in the box with length L, and particle mass m.
Find the expectation value of px for n=1 in a 1-d particle in the box with length L, and particle mass m.
Find the expectation value of p2x for n=1 in a 1-d particle in the box with length L, and particle mass m.
Using Δq2=?q2?-?q?2 and the expectation values you have now calculated, prove the Heisenberg Uncertainty principle holds true for the n=1 level of of the particle in the box.
A beaker with 100 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.60 mL of a 0.380 HCl solution to the beaker. How much will the pH c..
