1) Listen -5 The Ksp value for calcium sulfate [CaSO4] is 2.40 X 10 and a professor made 1825 mL of a CaSO4(ag) solution but then one of his graduate student accidentally poured in a 0.125 M solution of calcium phosphate [Cag(PO4)2] solution. You may ignore the additional volume coming from the Ca3(PO4)2 solution to make the calculation simpler. Calculate the new sulfate (SO42) ion concentration at equilibrium with this common ion effect. 6.40 x 10-5 5.25 x 10-5 6.21 x 10-5 5.44 x 10-5 201591..docx LAB EXP. #3 -..docx Show All

3. Suppose you are to measure the BOD removal rate for a primary wastewater treatment plant. You take 2 samples of raw sewage on its way into the plant and two samples of the effluent leaving the plant. Standard 5-day BOD tests are run on the four samples, with no seeding producing the following data: Sample Dilution Doi (mg/L) DOf (mg/L) Source 1 Raw 1:30 9.0 2.2 2 Raw 1:20 9.0 ? 3 Treated 1:15 8.5 1.5 4 Treated ? 9.0 1 a. Find the BOD5 for the raw and treated sewage, and the percent removal of BOD in the treatment plant. b. Find the DO that would be expected in sample 2 at the end of the test. c. What would be the maximum volume of treated sewage for sample 4 that could be put into the 300 mL BOD bottle and still have the DO after 5 days remain above zero?

Project PART I. Our Carbon Budget A major driver of global climate change is the emissions of greenhouse gases such as CO₂ into the atmosphere from human activities such as the burning of fossil fuels for transportation, electric power generation, manufacturing, agriculture, home heating, and so forth. Global average temper- atures are now slightly higher than 1° C above their pre-Industrial Revolution levels. Damaging sea level rise and extreme weather events (such as the recent wildfires in Canada that led to the unhealthy air in NYC last summer) will become an increasingly major problem around the world if global average temperature rises more than 1.5° C. Scientists estimate that the total additional amount of CO₂ that can be put into the atmosphere without reaching the 1.5° C level is about 51 parts per million (ppm) or approximately 400 Gigatons (Gt). Let's call 51 ppm our carbon budget. In this project, we want to use linear systems of differential equations to analyze the…

An action will release carbon tetrachloride to the atmosphere resulting in an air concentration at the source of 10° g/m3. Assume an adult inhales this contaminated air from 5pm to 9am on weekdays and 24 hours/day on weekends for their entire life, that it takes 5 minutes for the source to reach his window. Determine if the lifetime risk of developing a fatal form of cancer is acceptable.

A water quality monitoring found that local bayou contains 8.72x10-4 % (wt/wt) nitrate ion ( MW = 62.01 g/mol).  Yet the EPA standard for the nitrate content in a natural water body is 1.613x10-4 M or lower.  Is the mentioned bayou water in that location acceptable from the EPA standard ?   List your calculation steps (Density of bayou water is 1.0 g/mL).

2. Ferrous iron (Fe2+) must be removed from a steel plant wastewater to meet a pretreatment standard of 106 M. The proposed treatment scheme involves oxidizing the ferrous iron to ferric iron (Fe³+) in a CMFR. The ferric hydroxide precipitate (Fe(OH)3(s)) will be continuously removed from the bottom of the reactor to maintain steady state conditions. Dissolved oxygen will be added to the reactor by bubbling air through the solution. The pH in the reactor will be kept constant by the addition of a well-buffered caustic waste stream from another part of the plant. You are given the following information: Temperature=20 °C Waste stream flow rate Caustic stream flow rate = 1000 L/min = 100 L/min Concentration of Fe²+ in the waste stream=5x10-3 M Volume of reactor-72,500 L Saturation concentration of oxygen at 20 °C = 9.08 mg/L = 2.84x104 M Constant pH in the reactor = 9 Assume that there is no dissolved oxygen in either the waste stream or the caustic stream. The reaction occurs in two…

2. An 84 kg University of Toledo groundskeeper who is spraying a 100 mg/L solution of the insecticide dieldrin (MW = 381; logP = 4.56) on some trees exposes 100 cm“ of his skin to the solution over a 4 hr period. Dieldrin has a half-life of about 6 months, a volume of distribution of about 40 L/kg, and a dermal permeability of about 3 x 10° cm/sec. (a) Estimate the absorption rate during the exposure period assuming the blood concentration is much lower than the skin concentration (i.e., take the blood level to be zero in the skin absorption equation). (b) Estimate how it takes after exposure begins for the groundskeeper's plasma dieldrin levels to reach 1 ng/L. (c) Estimate the maximum plasma dieldrin concentration in ng/L that will occur in this groundskeeper due to this exposure. (d) Estimate how long it will take after exposure ends for the groundskeeper's plasma dieldrin levels to drop back down to 1 ng/L. %3D
