化学是一门以实验为基础的科学,所以实验在化学中的地位尤为突出,而每年中考中也必考的化学实验也以探究性实验为主,探究性实验的其中一种就是将很多实验装置串在一起,也就是我们所说的多米诺骨牌式的探究实验。今年各地中考中出现的也较多,这种题目的解题思路主要分为两步:一、实验的目的是什么?也就是要通过这套装置达到什么效果。二、理解每一个装置的作用,哪些气体进入了这个装置?出去的气体种类又有哪些?最后紧扣题目所给新信息,灵活应 Chemistry is an experiment-based science, so the position of experiment is particularly prominent in chemistry. The chemical experiment that must be taken in the middle school entrance examinations is also mainly based on exploratory experiments. One of the exploratory experiments is that many experiments Device string together, which is what we call the domino type of inquiry experiment. There are also many secondary examinations this year. The solution to this problem is mainly divided into two steps: First, what is the purpose of the experiment? What is the effect to be achieved through this device? Second, understand the role of each device, which gas into the device? Out of the gas species and what? Finally, the title of the new information closely linked, flexible
