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. c) cos(a+b)_1-tan atan B sin(a-B) tan a-tanß
Please show your work to help me understand how to solve this question. Calculate the pH of a 0.14 M HNO2 solution (Ka 4.5x 104) a. 13.10 b. 1.70 c. 11.90 d 0.85 2.10
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....
****NO HAND WRITTEN RESPONSES. NO COPYING OTHER or SIMILIAR RESPONSES. *** if you want a thumbs up, please be original!!! NO DUPLICATES! Thank you. 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...
Physics: Analytical Physics IMPORTANT! Typed step by step answer is preferred. If hand written, please make it clear and legible. Thanks :) (50 points) (Q2.9 in the textbook) A baseball (radius 0.0366 m, mass 0.0145 kg at the top of the Empire State Building (height 1250 ft). Calculate (a) the initial potential energy of the baseball, (b) its final kinetic energy, and (c) the total energy dissipated by the falling baseball by computing the line integral of the force of...
Please show all work typed or neatly written. 1. Determine Laplace transform of . 2. Determine if is periodic; if periodic, calculate the period. 3. Compute the inverse Laplace transform of . 4. For the circuit shown below, find the input/output differential equation.
can someone please help me? Calculate the Kb of Sodium Nitrite, NaNO2. It is the conjugate of Nitrous Acid. Show the reaction of the base Pyridine (see bottom chart) with water. 3. What is the pH of a 0.15 M solution of the base Ethylamine? 4. What is the pH of a 0.15M monoprotic acid, HA, that is 1.25% ionized?
