Jasmine Nassif Chemistry 102 Dr. Ogar August 1‚ 2013 Electrochemistry Part A: Voltaic Cells- use a voltmeter to measure the cell potential (E˚cell) between various 1.0 M aqueous reactant solutions‚ then using balanced half-cell rxns‚ calculate theoretical cell potential values and compare to experimental. Part B: Concentration Cell: Measure the cell potential of CuSO4 (aq) of two differing Molarities – one concentrated and one dilute- then use the Nernst equation to determine the theoretical

FINAL CASE CONCEPTUALIZATION PAPER In Building the Bonds of Attachment (Hughes‚ 2008)‚ Katie an abused‚ neglected‚ and poorly attached child‚ spent the first years of her life with parents who cared little about her. As a result she is an angry‚ unhappy‚ and manipulative kid. Is there any hope for her to grow up and become a healthy and happy adult? Daniel Hughes (2008) monitors Katie through her life with abusive birth parents and many foster homes‚ showing how

03/26/2015 Managing Human Resources Case #1 p.508-509 Anastasia Bond 1. Do managers like Janis Blancero face a more complicated decision when evaluating the personal requests of employees versus evaluating employees’ individual work performance? Explain. Yes‚ managers do expect employees to be productive motivated and fit which are the aspects that enable them to carry out their jobs well. Many managers like Janis are constantly in pressure. They have no problem with working flexibility requested

The different methods of measuring acids and bases in a solution By Starsky Intro to Biology September 26‚ 2011 Lab Partners: Kristen‚ Tania and Betty Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

rate change over time? How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a real enzyme because an enzyme’s job is to speed up the reactions and as time allotted. That did happen since the enzyme in our lab was able to make more chainobeads as time progressed. 4. Graph 5.

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

35 degrees Celsius. This covalent compound is corrosive to some metals and is combustible in oxygen. Ammonias structural diagram appears to be polar and therefore is highly stable. Water takes the form of liquid at room temperature. It is colourless‚ odourless‚ and a tasteless liquid. The boiling and freezing point of water differs depending on what kind and where the water is from.
