Teaching methods and tools
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 and criteria
The exam consists of a written test lasting two hours on n. 3 stoichiometry exercises and n. 3 theory questions. Each question is worth 5 points.
The stoichiometry exercises cover the following topics:
– gas
– weight ratios in chemical reactions. Purity and reaction yield
– concentration of solutions. Dilutions
– acid-base balance: pH of weak acids and weak bases; buffer solutions; hydrolysis
– batteries
– use of the electrochemical series
The theoretical part concerns the topics covered in lessons and reported in the program.
Only the use of a calculator is permitted during the exam.
The exams will be held in person unless otherwise indicated by the teacher following the health emergency situation. The results will be published on esse3 within 10 days of the exam
