一、将数学知识渗透进化学知识之中数学中的极值、数轴、直角坐标系、三角函数以及因式分解中的“十字相乘法”等知识在解决有关化学试题中都有快捷、独特的功效,解题时关键是要学会运用数学的思想去处理化学中的数据或结论.例1有机物的命名与它的构成规律紧密相连,如甲烷CH_4、乙烷C_2H_6、丙烷C_3H_8,按此规律,推断丁烷的化学式应该是——.分析:此题类似于数学中的找规律,解题的关键是要找到有机物命名与其构成的规律.
First, the mathematical knowledge to penetrate into the knowledge of chemistry among the mathematical extreme, the number of axes, Cartesian coordinates, trigonometric functions and factorization in the “cross multiplication method” and other knowledge in solving chemical problems are fast , The unique effect, the key to solve the problem is to learn to use mathematical thinking to deal with the data or conclusions in chemistry.Example 1 The naming of organic matter and its composition are closely linked, such as methane CH_4, ethane C_2H_6, propane C_3H_8, This rule, inferred that the chemical formula of butane should be -. Analysis: This question is similar to find the law in mathematics, the key to solve the problem is to find the rules of organic naming and its composition.
