When Technetium-95 decays by positron emission, the product nucleus formed is…

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.
