A KHP titration lab write up.
propyne and propane are light hydrocarbons produced by thermal and catalytic “Cracking” of heavier petroleumfractions. Propyne and propane have the same boilingpoints, but can be separated by distillation. Representative conditions are shown in the figure. A mixture of propyne and propane must be separated by distillation. Estimated thermodynamic values for the currents are in the […]
A sample initially contains 15.0 mg of Manganese-56. After 10.4 hours the sample contains 0.938 mg of Manganese-56. What is the half-life?
Now let’s investigate the relationship between displacement and velocity more closely. For that, we’re going to look at the changing slope of the yversus t graph using Tracker’s Data Tool: Double-click on the x vs. t graph to analyze it. (You should see all the x and t data in the table and a blowup of the graph from the Tracker screen.) Now click the button for Slope […]
