The world we live in is rich and colorful. In 2008, China successfully hosted the Beijing Olympic Games, including the majestic "Bird's Nest", the beautiful "Water Cube" and the lovely "Fuwa". They all left this world with good memories. "Shenzhou VII" proudly lifted off, and the astronauts completed the spacewalk for the first time in China's self-designed spacesuit ... These are closely related to chemistry, and it is precisely because of the magic of chemistry that a colorful world has been created. Chemistry is a science that benefits the world, and the progress of social civilization is inseparable from chemistry, which plays an important role in promoting the development of social life. We can understand it from the aspects of food, clothing, housing and transportation. Many problems faced by human beings in today's society, such as the development of energy conservation and clean energy, and the harmony between human beings and the ecological environment, depend on the development of chemistry to solve them. The Monkey King in Journey to the West has seventy-two changes and is the idol of many students. The chemical world has changed far beyond Qian Qian. As long as students study hard and study hard, they will master the change and become the "the Monkey King" in chemistry, making contributions to changing the living environment for mankind and synthesizing more excellent materials. .............
