10. A scientist performs an experiment and then records the times required for a certain chemical reaction to occur. The times for the reactions to occur are normally distributed and have a mean time of 38 s and a standard deviation of 2.3 s. Use z-score tables or technology to answer the following questions. a) What percentage of chemical reactions occur between 41 s and 43 s? b) What percentage of chemical reactions occur in less than 39 s?

Project PART I. Our Carbon Budget A major driver of global climate change is the emissions of greenhouse gases such as CO₂ into the atmosphere from human activities such as the burning of fossil fuels for transportation, electric power generation, manufacturing, agriculture, home heating, and so forth. Global average temper- atures are now slightly higher than 1° C above their pre-Industrial Revolution levels. Damaging sea level rise and extreme weather events (such as the recent wildfires in Canada that led to the unhealthy air in NYC last summer) will become an increasingly major problem around the world if global average temperature rises more than 1.5° C. Scientists estimate that the total additional amount of CO₂ that can be put into the atmosphere without reaching the 1.5° C level is about 51 parts per million (ppm) or approximately 400 Gigatons (Gt). Let's call 51 ppm our carbon budget. In this project, we want to use linear systems of differential equations to analyze the…

On rare occasions, faculty members have to produce reactants for their students to use. Students are similar to the judges on the show; they don't care about the sabotages or what the faculty member had to endure. However they expect reactants for their experiments to be available when they hit the lab. If I (the faculty member) come out of the stockroom with the following basket of reactants: (There may be a few I do not use or need... sort-of like having broccoli in the basket for making bacon and eggs sunny side up..): • HCI • HBr • hydrogen peroxide • 2-methyl-1-butene (fresh bottle, still with its seal unbroken, distilled and stored under nitrogen • 2-methyl-2-butene (fresh bottle, still with its seal unbroken,distilled and stored under nitrogen. • a cylinder of chlorine gas • a cylinder of bromine gas Tell me how you will prepare the following: A) You need to prepare 2-chloro-2-methylbutane as the only product of a chemical reaction.
