- The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing. It is important to consider what the experts say, but to also evaluate their statements. We will start with the scientific method. I want you to outline the scientific method from what you have been taught in previous classes. You can list steps, parts, process, short descriptions, whatever. If not taught in previous classes, then you will make your best guess about it.What is green chemistry? Choose the BEST answer. O Chemistry that uses only recycled chemicals. O Chemistry that makes something green in color. O Chemistry that comes from plants or uses plant materials. O Chemistry that uses non-toxic, non-harmful chemicals.A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of carbon tetrachloride, diethylamine, methyl acetate, tetrahydrofuran, and acetone. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information:
- concept that seemed difficult to you at first, but then after working on the concept, you were able to master it. Include a description of what made the concept difficult at first, and then discuss what you did in order to better understand the concept. If you are not familiar with The Onion, it's a satirical newspaper. That "NSF: Science Hard" article pictured above came out while one of my colleagues was in college. She said that it made her laugh so hard because she was in the middle of a very hard time analyzing data. But, She made it through.
