Hint: If you are having trouble tracking the effect from Pyap to AHvap. you can try creating a hypothetical graph using your excel data file (use a different file than the one you will submit). Create a new column where you change Pyap according to your answers to previous questions", then calculate a new Ln Pvap- You should graph both the real Ln Pvap and this hypothetical one on the same chart to see how the data compares. Ask yourself what changed and how that would affect AHvap. "For this to work you will need to use a proportion not a value. Example: let's say you decided that Pvap is being lowered so you need to decrease Pyap. You need to lower every Pvap by a proportion (say 10% lower) not an actual number. To do this in excel you can insert a "changed Pyap" column and use a formula such as Pvap cell"0.9 (that would be a 10 % decrease)…You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industria strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume o vinegar.
