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 LD50 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 LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 9 fluid ounce glass of the beverage you used in this lab and use this calculation to determine the number of such glasses of Allura Red sports drink required to reach the LD50 of 10,000 mg of Allura Red/kg body weight. Assume that the concentration of Allura Red in the beverage is 0.000038 M and the person has a body weight of 175 lbs. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL 2.205 lbs = 1 kg You may assume…

sk: The Chemistry of Respiration Quantities 2. Examine the two scenarios belowoi6g • Scenario A: 100 g of glucose in the presence of unlimited oxygen is metabolized through aerobic respiration. • Scenario B: 100 g of glucose in the absence of oxygen is metabolized through anaerobic respiration. Would the mass of products produced in Scenario A be greater than, less than, or equal to the mass of products produced in Scenario B? Justify your answer.

02-Sadra is a college student studying chemistry. In one of his labs, he needs to add 10 grams of sodium carbonate to a mixture and analyze the results. When he is measuring the chemical on a weight sensor, he notices the amount of Na2co3 he is weighing is much larger than everyone else's, yet the sensor reads 10 grams. He dumps the chemicals back into the container and reweighs it, only to get the same result. Which of the following is accurate in describing Sadra's weight sensor?
