在笔者日常的化学教学中,发现学生在解决某些化学问题时,常常能清楚理解问题的化学过程,却又找不到简便明了的方法解决之,有力不从心的感觉.如果能灵活的将这些问题抽象成数学模型,问题就迎刃而解,过程也大为简化.现列举一、二,以作抛砖引玉之用.1.利用一次函数解析式求解例1在标准状况下,将100mLH_2S和O_2的混合气体点燃,反应后恢复到原状况,发现反应后所得气
In my daily chemistry teaching, I found that when students solve certain chemical problems, they often can clearly understand the chemical process of the problem, but they can not find the simple and obvious method to solve the feeling of weakness .If we can flexibly use these Problem abstract into mathematic model, the problem is solved, the process is also greatly simplified.Currently cited one or two, as a starting point .1. Using a linear function to solve the solution 1 in the standard conditions, the 100mLH2S and O_2 gas mixture Ignited, the reaction returned to the original condition, found after the reaction gas
