Calculate the standard reduction potential (in V) for the following battery: Cu(s) | Cu2+(aq, 1M) || Ag+(aq, 1M) | Ag(s) Use the values listed in the provided standard reduction potential table.      

Work out problems: You must SHOW ALL OF YOUR WORK (no work – no points).  You also must show ALL relevant reactions (equilibria and/or 100% complete). State any assumptions you are making. Unless stated otherwise, assume the temperature is 25°C. Report answers to three significant figures. Circle your final answers. Problem 1. (15 pts.)             Determine the change in the boiling point of a solution that has 30.00 g of Mg(NO3)2 (148.32 g/mol) dissolved in 100.0 g of water. (Give

A buffer consists of 1.00 M HC7H5O2 (Ka=6.46×10-5) and 1.50 M NaC7H5O2.  What is the pH of this buffer?  Give pH to two decimal places.

Consider the following chemical reactions:   2 K(s) +  F2(g)  

The molar solubility of silver sulfate, Ag2SO4, is 1.44×10-2 M.  Determine the Ksp of silver phosphate.  Give your answer to two significant figures.   Ksp = x 10^

Work out problems: You must SHOW ALL OF YOUR WORK (no work – no points).  Unless stated otherwise, assume the temperature is 25°C. Report answers to three significant figures. Circle your final answers. Problem 1. (15 pts.)             Determine the change in the freezing point of a solution that has 15.00 g of NaCl (58.44 g/mol)                       dissolved in 200.0 g of water. (Give

A new student swipes her ID card to enter a closed lab classroom.  The student should be allowed to access the room, but the card swipe fails due a hardware fault in the card.  An intrusion detection system (IDS) analysis process decides that this event is a potential intrusion.  State the name commonly used for this type of IDS decision and explain why that name is appropriate. 

A student uses her smartphone to log in to a university application by entering her user ID and her password into a form in a browser. She also responds to a prompt with the model of her first car.This is an example of multi‑factor authentication. 

The left and right sides of both your keyboard and computer screen must be visible and your complete upper body must be centered in the camera’s field of view (as shown in the image above).
