Solutions Manual Online CHAPTER 1 SOLUTIONS 1. From Table A.10 in the Appendix, first obtain the atomic weights of the elements composing SO42: 2. From Table A.10 in the Appendix, the atomic weights of the elements composing SO 2 are: […]

CHAPTER 2 SOLUTIONS 1. Note that the figure showing conductivity versus time is not completely symmetrical; instead, it exhibits tailing. Thus, the solutions below are approximate. The asymmetry may occur due to several reasons. First, the cloud of salt is […]

28. From Fig. 2.37, the Earth’s surface receives wavelengths of 0.3 mm (300 nm) and above. Thus, only aniline will absorb sunlight and potentially degrade by direct photodegradation; the anilinium ion will not. A water treatment scheme using sunlight should […]

c. From Eq. (2.56), the methanogenic reaction occurring is: 43. From Eq. (2.41): Alk ¼CBCA Given that the concentrations of base cations are assumed negligible, the above equation can be written: Alk ¼CA¼103:52 eq=liter ¼NO3 ½þ2SO 42  Given that […]

CHAPTER 3 SOLUTIONS 1. a. Using Eq. (3.2): b. Using Eq. (3.5): v¼qa n¼1104cm=sec 0:2¼5104cm=sec c. Transmissivity is the product of an aquifer’s hydraulic conductivity and its thickness: T¼5103cm=sec5m1m 100 cm ¼2:5104m2=sec Discharge per unit of distance perpendicular to the […]

21. a. The relevant redox reactions are: Given that organic matter is being oxidized to CO 2 at a rate equivalent to 1 mM/day, and 1 mol O 2 oxidizes 1 mol CH 2 O, oxygen can be used as […]

33. a. From the geometry of the building foundation, it is evident that the water table must be lowered by 2.5 m at a distance of 15 m from the well. Given the transmissivity and radius of influence, use Eq. […]

c. If there is an inversion at 50 m, assume the soot plume becomes fully mixed vertically beneath it. Then use Eq. (4.20) to estimate the 30. Over the hour travel time, the solvent vapor concentration is being reduced from […]

CHAPTER 4 SOLUTIONS 1. a. Using Eq. (4.14) and assuming no sinks for CO and a negligible concentration of CO outside: b. Given the assumptions of no sinks for CO and a negligible CO concentration outside the room, use Eq. […]
