Toxic handlers

Can you please answer question #8? Thank you

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

This assignment is designed to help you learn how to determine total costs by combining direct and indirect costs for a particular department. In this GHA, you will be determining the total costs for three departments: (1) Physical Therapy (2) Occupational Therapy and (3) Speech Therapy. To determine the total costs, you will need to add the direct costs to the indirect costs using the template provided below. Please use the example provided in the assignment description if you find that you need some support understanding the required calculations. DIRECT COSTS The direct costs for each department are easily identifiable, because they are the costs that are directly attributable to the department. The direct costs are as follows: Physical Therapy (PT) Occupational Therapy (OT) Speech Therapy (ST) Total Direct Costs INDIRECT COSTS The indirect costs will need to be allocated to Physical Therapy (PT), Occupational Therapy (OT), and Speech Therapy (ST). The indirect costs in this…

Based on the data in the table, summarize what was shown here, what did they do here? And was this lab successful or not?     Substance  Physical Appearance Odor Density (g/mL) Reacts with NaHCO3 1.      Benzaldehyde  Clear liquid or almost pale yellow It smelled like almonds  1.00 No, significant reaction 2.      MTBE Colorless  Fruity smell to it 1.236 -1.247  No chemical reaction occurred 3.      Urea White solid  A very strong order of ammonia  0.791 No reaction occurred   4.       Acetone Colorless Pungent odor like nail polish remover 1.335 No, did not react with sodium bicarbonate 5.      Glycerol Colorless N/O 1.044 No, it did not cause a reaction 6.      Citric Acid colorless then turns white with sodium bicarbonate added N/O 1.044 Yes, caused fizzy/bubbles to it.

2. Which of the following statements is FALSE regarding the log-kill hypothesis? a. It predicts the 100% eradication of cells after some period of time. b. It is an application of first-order kinetics. c. It predicts that cell counts decrease exponentially with repeated cycles of application. d. It applies to sterilization as well as other fields such as chemotherapy. e. Each cycle of application kills the same fraction (or %) of cells just prior to that cycle.

Ammonia must be eliminated from wastewater before it can be reused, recycled, or discharged. Describe the three major steps that are used to convert harmful ammonia into a harmless derivative. Your answer must be specific and include any appropriate chemical formulas or names of chemical or biological reagents. Mention, when appropriate, the toxicity of any of the components or how their production can get in the way of efficiently eliminating ammonia from wastewater.

4) But the real angler continues, regardless of the local sage. What sort of tone does the author create by using the connotative effects of the word sage in paragraph 6? The word "sage" is used primarily as a joke, gently mocking the fishing guide who cannot force fish to A) appear or guarantee good fishing to a paying customer.

The author is being highly critical, even condemning. of the ignorance of these so-called "sages who can't help fisherman catch fish. The word sage" in this context has no connotaive D) effect on the tone or meaning of this entire passage.

Calculate the concentration in ppm of Cd in a 2.00 mL sample which has been shown to contain 16.4 μg Cd. Assume the sample has a density of 1.00 g/mL. Show your work for full credits (just explain step by step and put the answer at the end)
