Greenwashing is a major problem. Companies will say they are using practices that benefit the environment while really not taking any steps to do so. An example is Terracycle - a company that is supposedly able to recycle non-recyclable plastics and by-products - but which went over a year without collecting products from any of their customers. How can consumers navigate the labels to determine if products are actually sustainable.

What is meant by the statement, “Perhaps no other single natural resource is as influential as soils.”? (Why is soil so important?) What are the 5 main functions of soil (list & describe each)

Scientists can learn a great deal about a community's drug use (both legal and illegal) by analyzing the contaminants in wastewater. In a recent study in New York State, chemists measured the concentration of cotinine, a derivative of nicotine that i produced in the liver and excreted in the urine of tobacco users. The chemists found the average cotinine concentrations in the wastewater stream was 1.43 µg/L. a Ι Ι H- b HH H H-C C-N: C=0: TH HH Jonutis/Shutterstock Revell, Introductory Chemistry, 2e, © 2021 W.

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.

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…
