Prerequisites
This teaching activity does not require any prerequisites
Reading/Bibliography
THEORY Martin S. Silberberg “Chemistry” – Ed. McGraw-Hill Alternatively: M. Schiavello, L. Palmisano -Fundamentals of Chemistry- EdiSES.
STOICHIOMETRY Giomini, Balestrieri, Giustini – Fundamentals of Stoichiometry – EdiSes.
Teaching methods
The teaching activity is frontal with theoretical lessons with projection of teaching material in electronic format, made available online. The teaching is accompanied by stoichiometry exercises in the classroom.
Assessment methods
The exam consists of a two-hour written test covering three stoichiometry exercises and three theory questions. Each question is worth 5 points. The stoichiometry exercises cover the following topics: – gases – weight ratios in chemical reactions; purity and reaction yield; concentration of solutions; dilutions – acid-base equilibrium: pH of weak acids and weak bases; buffer solutions; hydrolysis; batteries – use of the electrochemical series. The theory portion covers the topics covered in class and listed in the syllabus. Only calculators may be used during the exam. Exams will be held in person unless otherwise indicated by the instructor due to the health emergency. Results will be published on esse3 within 10 days of the exam.
