With the continuous development of information technology, multimedia-assisted teaching has become an inevitable trend of classroom teaching reform. It is not only intuitive, visual, and vivid, but also enables conversion between size, distance, speed, and reality, with large amounts of information and convenient delivery. In order to improve the efficiency in the 45-minute classroom teaching and to conduct high-density and high-capacity teaching, the application of multimedia is imperative. The Chemistry Department has an advantage in this respect. The objects of chemical research are microscopic molecules, atoms and other particles. Movement and change laws, chemical concepts and principles are mostly abstract, material
