The course focuses primarily on chemical equilibrium and kinetic principles associated with both natural and engineered aquatic systems. Students will solve quantitative chemical equilibrium and kinetic problems and develop an understanding of chemical concepts/principles which are the basis for design experiences in both academic programs and professions in environmental engineering. Textbook: “Water Chemistry” by Mark Benjamin, 2nd Edition (ISBN 1-4786-2308-X or 978-4786-2308-3) Prerequisites: CHM 2046 or CHM 2096 and MAC 2311 or MAC 2233. Relationship of this course to the objectives of the Environmental Engineering Science Program: The fundamental understanding of aquatic chemistry principles emphasized in this course will allow students to acquire skills needed to adequately deal with pollution prevention and control in both natural and engineered aquatic systems. This course is a tremendous asset for professional careers in environmental engineering, with obvious benefits for society. Student outcomes addressed in this course: Students who successfully complete this course should be able to: (1) identify, formulate, and solve engineering problems related to water pollution, (2) apply knowledge of mathematics, chemistry, and engineering; and (3) acquire knowledge on fate and environmental health impacts of pollutants in aquatic systems. Exam and homework assignments: There will be a total of three tests and several homework assigned throughout the semester. Solutions to the homework and exams will be posted on Canvas. Final grades in this course will be determined on the following basis: Test-1 20% Test-2 25% Test-3 30% Homework 25% Dr. Bonzongo Office hours: TBA Location: 320 Black Hall Avni Solanki (TA) Office hours: TBA Location: TBA 90–100 A 87–89 A83 –86 B+ 80–82 B 76–79 B+ 73 –75 C 70–72 C 66–69 C+ 63 –65 D 60–62 D 56–59 D<56 E In order to graduate, students must have an overall GPA and an upper-division GPA of 2.0 or better (C or better). Note: a C- average is equivalent to a GPA of 1.67, and therefore, it does not satisfy this Grading Scale: 1 graduation requirement. For more information on grades and grading policies, please visit: https://catalog.ufl.edu/ugrad/current/regulations/info/grades.aspx Class Attendance: Students are encouraged to attend all classes. History indicates that students who do not attend class do poorly on examinations and suffer the consequence of low grades. Canvas: We will use Sakai for this course. Notes consisting of power point slides to be used in class, homework assignments and other information will be posted on UF-Canvas site. Online information regarding common tools in Sakai is provided for students. This information is available via the Student Intro to ELS link at http://lss.at.ufl.edu. Students needing assistance with the computer and technical requirements for using E-learning, should seek this assistance from the UF HelpDesk http://helpdesk.ufl.edu/ 352-392-4357, helpdesk@ufl.edu). The HelpDesk can also assist students who are having trouble logging into E-learning. Make-up Exam Policy: Make-up exams are only given for medical reasons. A student may request a make-up exam if they cannot attend the scheduled exam for medical reasons and can show proofs of such reasons (e.g. letter from a PCP or hospital). The student must contact the instructor (bonzongo@ufl.edu) before the exam to state that he/she will not be able to attend the exam. Penalties on overdue homework assignments: Overdue assignments will be penalized at a rate of -50 points per day. For instance, a homework assignment due on 10/10/2015 and turned in on 10/11/2015 will be graded over 50 and not 100. Students with Disabilities: Students requesting classroom accommodation must first register with the Dean of Students Office. The Dean of Students Office will provide documentation to the student who must then provide this documentation to the Instructor when requesting accommodation. Cell Phones: Cell phones must be turned off or put in silent mode at the beginning of class; use of cell phones for calls or messaging during class is prohibited. Academic Honesty: All students admitted to the University of Florida have signed a statement of academic honesty committing themselves to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a UF student and to be honest in all work submitted and exams taken in this course and all others. Software Use: All faculty, staff, and students of the University of Florida are required and expected to obey the laws and legal agreements governing software use. Failure to do so can lead to monetary damages and/or criminal penalties for the individual violator. Because such violations are also against University policies and rules, disciplinary action will be taken as appropriate.
