Part A Which route would be better: one that produces a small amount of hazardous waste or one that produces a large amount of nonhazardous waste? Which green chemistry metric accounts for this dilemma? Match the items in the left column to the appropriate blanks in the sentences on the right. Reset Help minimize The best route is because it should the E-factor and maximize the effective mass yield. the one that produces a small The accounts for this dilemma as it looks at the amount of relative to amount of hazardous waste the amount of E-factor product made the one that produces a large amount nonhazardous waste materials used difficult to choose hazardous reagents used waste produced Submit Previous Answers Request Answer

A Water Quality Standard will be developed for radioactive isotope “Iron-55” which has physical (radioactive) and biological half-lives of 2.7 and 1.6 years, respectively. Through toxicological studies scientists decided “spleen” as the critical organ and the critical accumulation of Iron-55 in spleen has been determined to be 0.5 gram. Assuming radioactive exposure is only due to drinking water consumption and average life expectancy is 75 years. a) What should be the Maximum Concentration Level (MCL) as mg/L for Iron-55 in drinking water.  b) How long does it take to eliminate 95% of this radioactive isotope from human spleen after the person gives up on drinking water contaminated with Iron-55?

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.

Create a model that explains a nuclear reaction within the context of its application :  Nuclear fission reactors  An equation for the nuclear reaction in your model  A visual representation of the nuclear reaction occurring  A written explanation of the reaction and how energy and matter are transformed and conserved throughout the reaction  The context and/or application of the nuclear reaction  Where does the reaction occur?  What impact or relevance does this reaction have to society?

You will research how the energy is extracted or produced and try to be very detailed about the process and the chemistry involved (stating equations and reactions). You will also research the impact on the environment when using or producing fuels. Investigating fossil fuel: How is it produced? What is the chemistry involved (stating equations and reactions)? What is the impact on the environment? 300-400 words Investigating nuclear energy: How is it produced? What is the chemistry involved (stating equations and reactions)? What is the impact on the environment? 300-400 words Investigating biofuel: How is it produced? What is the chemistry involved (stating equations and reactions)? What is the impact on the environment? 300-400 words

The COVID-19 pandemic forced many people to work from home for extended periods. During these periods, many cities reported unusually low levels of smog. Suggest an explanation for this observation.

Experiment 4: Preparation and Properties of Hydrogen and Oxygen Gases Toriana Mieer -Jones Name: Section: Lab Instructor: L/26 Date: Pre-Lab Exercise 4 1. In this experiment, simple chemical reactions are used to generate small quantities of hydrogen and oxygen gases. These methods would be too expensive and too complicated if large quantities of these gases were needed, however. Use your textbook, a chemical encyclopedia, or an online source to look up the major industrial methods of preparing very large quantities of these gases. Summarize your findings here. ono od te led bateono to n

3) Carbon-14 is constantly being produced in the upper atmosphere, and the amount is in equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% of its original 14C left. Determine the age of the shell. Show your work.

1.Explain the slogan about chemical safety " A spill, A slip, A hospital trip" 2.How do you apply 5s(sort, set in order, shine, standardize, sustain) to attain chemical safety at home and in school?. Enumerate

When reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded at 1:23 p.m. on April 26, 1986, a great plume of radioactive isotopes erupted into the air and spread for thousands of miles. Most of the isotopes emitted immediately following the blast were of the element iodine. Which of the glands of the endocrine system would be most seriously—and immediately— affected by the blast, and how do you think this would become evident in the nearby population?

Situation: “The coronavirus disease (COVID-19) is an infectious disease caused by a new strain of coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.              On 30 January 2020, the Philippine Department of Health reported the first case of COVID-19 in the country with a 38-year-old female Chinese national. On 7 March, the first local transmission of COVID-19 was confirmed. WHO is working closely with the Department of Health in responding to the COVID-19 outbreak.” Aki and her family were alarmed with the news they watched and so first thing in the morning they rush to the nearest convenient store to secure disinfectant and sanitizers but unfortunately the store already had empty shelves of the essentials they needed. They went to other stores searching and to their dismay they acquired nothing. They were on their way home when she suddenly remembered her past lesson on “solutions”, and so she immediately ran back to…
