Step by step
Solved in 2 steps
- Is it acceptable to recycle the containers of hazardous chemicals? Why or why not? Explain your answer within the context of chemical safety.Explain the laboratory rules for waste disposal.Which activities are likely to cause contamination of stock chemicals in the laboratory? pouring out chemicals from the stock container into another container returning unused stock chemicals to their original container at the end of an experiment swirling the container of stock chemicals to ensure that the contents are thoroughly mixed spilling some of the chemicals on the lab bench and then returning them to the original container inserting a dirty pipet into a container of stock chemicals
- List five (5) information that you should read on a chemical container and briefly describe their significance in relation to safety.A large population of Japanese beetles infests a plot of cropland. In response to the infesta tion, farmers treat the land with organochlorine pesticides. As a result of the treatment, the population of Japanese beetles is eradicated within the cropland, along with the popula- tions of multiple other insect species. Which of the following statements explains the most likely reason for the death of so many insect populations? Organochlorine pesticides are persistent organic pollutants that interfere with the respi- ratory system of the insect populations. Organochlorine pesticides are endocrine disruptors that interfere with the growth hor- mones of the insect populations. Organochlorine pesticides are persistent organic pollutants and interfere with the re- productive organs of the insect populations. Organochlorine pesticides are endocrine disruptors that interfere with the transmission of nerve impulses, resulting in spasms, seizures, and death of the insect populations.What is the role of environmental chemistry in the development of sustainable technologies?
