10/17/11 OUTLINE FOR REPORT ON EXP V: CHLORIDE ISE (50 points max.) I. Purpose: Use one or two complete sentences to give a concise statement of the purpose of the experiment. Experimental Parameters: Theoretical Equations: Give the theoretical equations which relate the potential of the ISE/SCE pair to the activity of chloride and the concentration of chloride. What must be true if the latter equation is to be valid? What is the ideal slope of a plot of potential versus the logarithm of the concentration

three times from each height‚ found the mean. Our Y value represents the average bounce heights in centimeters and X represents the drop height in centimeters. We created a scatter plot to show our data (below). The line of best fit went through the points (80‚48.3) and (90‚54.3). To find the slope of the line we used the slope formula: M=(Y2 -- Y1)/(X2 -- X1). If (80‚48.3) is X1 and Y1 then (90‚54.3) is X2 and Y2. After this you take X2 and subtract it by X1 and the same with Y1 and Y2. So 90-80 is

second lab activity dealt with two-point acuity. Different parts of our body performs a specific function that which they were built to execute. However‚ the sensitivity each surface of our body reveals to be different. Some areas of the body will have a variety of sensory receptors‚ which requires more sensory input. Therefore‚ body parts have their own sensation depth that one can measure through two-point acuity. Results Participant #1: Initially‚ the researcher placed the compass points with

The Boiling Frog Theory on Population Systems thinkers have given us a useful metaphor for a certain kind of human behavior in the phenomenon of the boiled frog. The phenomenon is this. If you drop a frog in a pot of boiling water‚ it will of course frantically try to clamber out. But if you place it gently in a pot of tepid water and turn the heat on low‚ it will float there quite placidly. As the water gradually heats up‚ the frog will sink into a tranquil stupor‚ exactly like one of us in a

The alcohols tested will be methanol (1 carbon atom)‚ ethanol (2 carbon atoms)‚ propan-1-ol (3 carbon atoms)‚ butan-1-ol (4 carbon atoms) and pentan-1-ol (5 carbon atoms). Variables Variable Description Independent This is the variable that will change; the chain

Over the centuries‚ immigration has benefited the United States for the use of slavery‚ but what about for the economy or just the country itself? The US has been given the name‚ “The Boiling Pot‚” because we have a lot of different races combined into one country. Have you ever wondered how the boiling pot could’ve just been some scrap metal if immigrants hadn’t come into the United States and built it a little? Some people think that immigrants just want to steal our jobs‚ but do they really? Maybe

The experimental melting point range of the desired alkene product‚ trans-9-(2-phenylethenyl) anthracene‚ was found to be 132-134 ˚C‚ in comparison to the literature value melting point range of 130-132˚C‚1 it was slightly higher than expected. Overall‚ the experimental melting point range varied from the initial melting point temperature and maximum melting point temperature by 2˚C. As the experimental melting point had a small range of temperature variance and was above that of the literature value
