- 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? Discuss.arrow_forward1-12 The life expectancy of a citizen in the United States is 76 years. Eighty years ago it was 56 years. In your opinion, what was the major contributor to this spectacular increase in life expectancy? Explain your answer.arrow_forwardSome scientists think there are living things smaller than bacteria (New York Times, January 18, 2000, p. D1). Called nanobes, they are roughly cylindrical and range from 20 to 150 nm long and about 10 nm in diameter. One approach to determining whether nanobes are living is to estimate how many atoms and molecules could make up a nanobe. If the number is too small, then there would not be enough DNA, protein, and other biological molecules to carry out life processes. To test this method, estimate an upper limit for the number of atoms that could be in a nanobe. (Use a small atom, such as hydrogen.) Also estimate how many protein molecules could fit inside a nanobe. Do your estimates rule out the possibility that a nanobe could be living? Explain why or why not.arrow_forward

- In an attempt to introduce some intrinsic motivation on why it is important for everyone to change their view of being required to take chemistry. Research how concepts in chemistry are involved in your chosen discipline and field of interest. Please do not focus on concepts in Basic Chemistry, investigate the connection between chemistry and the discipline and field you are interested in.arrow_forwardThe total weight of copper in a vehicle ranges from 15 kilos for a small car to 28 kilos for a luxury car. As a material scientist you are analyzing a luxury car that has 30 kilos of copper. What does this indicate about the car’s performance? Where is copper (Cu) likely to be located in the car? Discuss the physical and chemical properties of copper in your answer.arrow_forwardDiscuss some ways in which chemistry has changed technology. Give one or more examples of how chemistry has affected another science.arrow_forward
- If all scientists use the scientific method to try to arrive at a better understanding of the world, why do so many debates arise among scientists?arrow_forwardConfronted with the box shown in the diagram, you wish to discover something about its internal workings. You have no tools and cannot open the box. You pull on rope B, and it moves rather freely. When you pull on rope A, rope C appears to be pulled slightly into the box. When you pull on rope C, rope A almost disappears into the box. a. Based on these observations, construct a model for the interior mechanism of the box. b. What further experiments could you do to refine your model?arrow_forwardWhat if everyone in the government used the scientific method to analyze and solve societys problems, and politics were never involved in the solutions? How would this be different from the present situation, and would it be better or worse?arrow_forward
