Chapter 11.1, Problem 11.1YT
You Decide A Lifetime of Food
During your lifetime, it has been claimed that you will eat about 700 times your adult body weight. Is this statement in the ballpark? Do a calculation to find out. State your assumptions clearly.
Hint: You might assume a life span of 78 years and that your present weight is your adult weight. Estimate the weight of food eaten daily at present, and use these data to project your lifetime food consumption.

In the course of a conversation, you observe that three of your friends like horror movies. Horror movies happen to be your favorite type of movie as well. You also know
that all of these friends were born in the same week that you were, even in the same year.
An astrology-loving friend hypothesizes that people born in that week like horror movies more than other genres of movies. You decide to use the scientific method to test
this hypothesis.
Part A
What should you do next?
O Come up with a theory to explain why movie preference is related to birth week.
O Perform experiments to test your hypothesis.
O Propose several alternative hypotheses.
O Refine your hypothesis.

4. Gasoline can be reasonably approximated as C9H20 with a density of 0.718 g/mL. Diesel can be reasonable approximated as C14H30 with a density of 0.763 g/mL. (Both gasoline and diesel are complicated mixtures. These formulas are something like weighted averages of the formulas of the different components, where the weighting is based on various quantifiable behaviors. That is, using these artificial formulas for gasoline and diesel allows one to calculate average properties that match what petroleum engineers might measure.) The enthalpy change from burning one mole of gasoline is -6160 kJ. The enthalpy change from burning one mole of diesel is -7940 kJ. Determine which fuel generates the biggest enthalpy change per gram burned, and which generates the biggest enthalpy change per mL burned.

- The Chemistry in Focus segment titled Dr. Ruth—cotton Hero discusses the enormous contribution of Dr. Ruth Rogan Benerito to the survival of the cotton fabric industry in the United States. In the discussion, it was mentioned that Dr. Benerito became a chemist when women were not expected to be interested in, or good at, scientific subjects. Has this attitude changed? Among your own friends, approximately how many of your female friends are studying a science? How many plan to pursue a career in science?

Apply the methods of science to arrive at a technique that will give the most juice from a lemon. Carry out experiments and draw conclusions based on them. Try to generate a hypothesis to explain your results.arrow_forward

- As stated in the text, there is no one scientific method. However, making observations, formulating hypotheses, and performing experiments are generally components of “doing science.” Read the following passage, and list any observations, hypotheses, and experiments. Support your answer. Joyce and Frank arc eating raisins and drinking ginger ale. Frank accidentally drops a raisin into his ginger ale. They both notice that (lie raisin falls to the bottom of the glass. Soon, the raisin rises Lo the surface of the ginger ale, then sinks. Within a couple of minutes, it rises and sinks again. Joyce asks. “I won der why that happened?” Frank says. I don’t know, hut let’s see if it works in water.” Joyce fills a glass with water and drops the raisin into the glass. After a few minutes, Frank says, “No, it doesn’t go up and down in the water.” Joyce closely observes the raisins in the two glasses and states, “Look, there are hubbies on the raisins in the ginger ale but not on the raisins in the water.” Frank says, ‘it must be the bubbles that make the raisin rise.” Joyce asks, “OK, hut then why do they sink again?”arrow_forwardChapter 1, End of the Chapter, Active Learning Questions, Exercise 57 The dosage for an antibiotic is prescribed at 8.0 mg per kilogram of body weight, taken twice daily for two weeks.
