- What is Reagent Grade classification of chemicals and give some examples.Is it acceptable to recycle the containers of hazardous chemicals? Why or why not? Explain your answer within the context of chemical safety.Identify and provide an explanation of what “Separation Science” entails and its importance with the respect to the chemical analysis of food. Provide an example.
- What is calibration and why is it essential in relation to food analysis? Provide examples.Chemical Manufacturers Association (CMA) and four companies that manufacture chemicals challenged a test rule promulgated by the Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA). The plaintiffs asserted that the EPA must find that the existence of an unreasonable risk of injury to health is more probable than not before it may issue a test rule under the Act. In response, the EPA claimed that it may issue a test rule under the TSCA if the agency determines that there is a substantial probability of an unreasonable risk of injury to health. The test rule required toxicological testing to determine the health effects of the chemical, 2-ethylhexanoic acid, and imposed on exporters of this chemical a duty to file certain notices with the EPA. What standard should be applied? Why?During a combustion test, the following observations (Table 2) were recorded. By using suitable examples, explain the findings

- 4. How sizing down to Nano affect material properties?List five (5) information that you should read on a chemical container and briefly describe their significance in relation to safety.Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD 50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD 50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD 50 value for humans is the same as for rats. Calculate the number of number of glasses of Allura Red sports drink, each containing 8.8 mg of Allura Red, required to reach the LD 50 of 10,000 mg of Allura Red/kg body weight. Assume the person has a body weight of 165 lbs. 2.205 lbs 1 kg !! You may assume two significant figures but do not use sčientific notation. Do not include units with your answer.
