化学是一门以实验为基础的学科,同学们看看这样一堂实验课——空气中氧气体积含量的测定。老师:二百多年前,法国化学家拉瓦锡用定量的方法研究了空气的成分。现在,我们也仿照拉瓦锡测定空气组成的实验原理进行
Chemistry is an experiment-based discipline. Students look at this kind of experimental course—the determination of the volume of oxygen in the air. Teacher: Two hundred years ago, French chemist Lavoisier used a quantitative method to study the composition of air. Now we also follow the experimental principle of measuring the composition of air by Lavoisier.
