学习化学需要科学的方法,利用化学实验对物质及其变化进行科学探究,是学习化学的重要方法,化学的许多重大发现和研究成果都是通过实验得到的。所以,同学们通过实验观察现象,记录、分析数据,可以发现未知事实真相和验证已知化学原理。让我们一起探究下列实验操作新颖命题,走进迷人的 Learning chemistry requires a scientific approach. Using chemical experiments to scientifically study matter and its changes is an important way to learn chemistry. Many of the major discoveries and research results in chemistry were obtained experimentally. Therefore, students through the experimental observation of the phenomenon, record, analyze the data, you can find the unknown truth and verify the known chemical principles. Let us explore the following experimental operation of new propositions, into the charming
