Abstract:

The essay focuses on the detailed analysis and solutions of the two questions in the 30th Chemistry Olympiad and conducts further discussion on the subjects. First, the scientific background of the Nierate test was introduced and the analysis of the information of the magnetic moment was discussed in depth; second, the background and solution of the "methanol to hydrogen" problem in the final competition were elucidated. The author aims to broaden the research background and relevant knowledge of the two questions, thus encouraging readers to understand comprehensively the scientific thought behind the questions and enjoy the learning of chemistry.

Key words: Chemistry Olympiad, Discussion on questions
