The material is structured in such a way that, faced with complex questions that cause difficulties, you will immediately find an explanation from the author. For an inquisitive reader who wants to broaden his horizons, the Self-Teacher will give the opportunity to master this subject "from scratch." After reading it, you can not fall in love with this interesting science - chemistry!
