	Verification of learning
	THE ASSESSMENT OF THE GOALS' ACHIEVEMENT WILL BE DONE THROUGH A WRITTEN TEST AND ORAL INTERVIEW. IS AN ESSENTIAL CONDITION FOR PASSING THE EXAM THE ABILITY TO CORRECTLY FORMULATE THE MASS BALANCE IN THE PRESENCE AND IN THE ABSENCE OF CHEMICAL REACTIONS, THE ABILITY TO READ AND INTERPRET THE MAIN THERMODYNAMIC DIAGRAMS, THE PROPER APPLICATION OF THE RELATIONS OF PHYSICAL EQUILIBRIA IN THE IDEAL CASE, THE CALCULATION OF CHEMICAL EQUILIBRIUM FOR GASEOUS REACTIONS. THE STUDENT REACHES THE LEVEL OF EXCELLENCE IF IT PROVES TO BE ABLE TO DEAL WITH UNUSUAL ISSUES, NAMELY NOT SPECIFICALLY TREATED IN CLASS LESSONS. THE FINAL MARK WILL DEPEND ON THE DEGREE OF MATURITY ACQUIRED ON THE COURSE CONTENTS AND ON THE METHODOLOGY EXPOSED IN THE COURSE, TAKING INTO ACCOUNT THE QUALITY OF WRITTEN TEST AND COLLOQIUM.
