Calculate the pH of a 1.56 M solution of NaNO2. Show all your work and assumptions.
IMPORTANT: Step by step *typed* format preferred. If
hand written, please write clearly and legibly. Please be sure
answer is CORRECT. Thanks!
How fast must a meter stick be moving if its length is observed to shrink to 0.7 m?
Prove the identity. Please
attach a hand written solution with full work if possible, its
easier for me to visualize than the typed format.

This question has two parts: What is the pH of a 0.1 M solution of HF? b) What is the percent dissociation of a 0.1 M HF solution? PLEASE SHOW WORK TYPED. It's hard to understand some handwritings so this is the easiest way I can ensure I can actually read the answer and understand it.
Step by step typed format preferred. If hand written,
PLEASE write clearly and legibly. Thanks!
5. (20 pts) Show that (x3) 0 for a simple harmonic oscillator wave functions with unspecified n. (Hint: Use Symmetry properties of the Hermite Polynomials) a. (15 pts) a. Show that the solution to the free particle Schrodinger equation dx is: ψ Ae-ikx + Beikx where k = b. (5 pts) Which term vanishes (blows up) if the particle for xO region. (note: k >0)
A) First consider C14 nuclear, why this nuclear is not stable? what types of decay it will likely go? Write a nuclear chemical equation for that. B) The half-lifetime for C14 is 5732 years. In C-14 dating, what assumptions do scientists assume in C-14 dating? Discuss how good are the assumptions. C) An ancient skull has carbon-14 decay rate of 0.86 disintegration per minute per gram of C (0.86 dis/min gC). The present day Carbon-14 decay is 15.3 dis/min gC....

Processes, along with the kernel, are the only means of accomplishing work on a computer. Therefore, writing a program that creates a breach of security, or causing a normal process to change its behavior and create a breach, is a common goal of crackers. Even most nonprogram security events have as their goal causing a program...
