You have 200 gallons of a vegetable wash that is made from a solution of acetic acid (60.052 g/mol, ka=1.75×10^-5) with a pH of 3.3 and a container of vinegar with 5% acidity from Acetic acid at a pH of 2.4. You use 150 gallons of the solution cleaning potatoes and need to refill your wash container. How much of the vinegar do you add to the 50 gallons of remaining vegetable wash so, when you dilute with water to a final volume of 200, the pH of the solution will remain 3.3?

Dr. X claims that she has found a new remedy (carrot extract) to cure acne. She scores an interview with the science writer for a local newspaper, and gets a brief article written about her and her claims in that newspaper. The article does not contain any experimental evidence, but mentions that Dr. X accidentally splashed some carrot extract on her face and found that the acne was reduced a few days later. Student Y finds the article and cites it as a source for a paper he is writing for class, as evidence that acne has been cured. (a) Is this finding a fact, a theory, a hypothesis, or an observation? Explain why you think so. (b) Was it OK for Student Y to use the newspaper article as evidence for his paper? Explain why or why not.
