In 1993 the Minnesota Department of Health set a health risk limit for 1,2-dlbromoethane In groundwater of 4.00 ng/L. Suppose an analytical chemist receives a sample of groundwater with a measured volume of 78.0 mL. Calculate the maximum mass In micrograms of 1,2- dibromoethane which the chemist could measure In this sample and still certify that the groundwater from which it came met Minnesota Department of Health standards. Be sure your answer has the correct number of significant digits.

In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 53.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. CH₂(g) + 20₂(g) → CO₂(g) + 2H₂O(g) ALEKS - Rafia Riaz - Learn Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then,…
