数学知识在化学中有着广泛的应用.将化学问题抽象为数学模型后,再用数学方法去解决,有利于各学科知识的融会贯通,有利于学生综合素质的提高.本文通过实例说明数学方法在解决初中化学问题中的应用.1不定方程法例1某含氧酸的化学式为HnXO2n-1.则X同价态氧化物的化学式可能是().(A
Mathematical knowledge has a wide range of applications in chemistry. Abstracting chemical problems as mathematical models and then solving them with mathematical methods is conducive to the integration of knowledge in various disciplines and is conducive to the improvement of students’ comprehensive qualities. This article illustrates the solution to mathematics through examples. The application of junior high school chemistry issues.1 Indefinite equations The chemical formula of an oxo acid is HnXO2n-1. Then the chemical formula of the X valence oxide may be (). (A
