化学实验具有一定的危险性,安全实验的关键是要按照操作规定进行实验,危险也能变为安全。反之,安全也变得不安全。但也不要害怕,也不必满腹恐惧不敢动手实验;要熟悉操作规定,了解反应规律,不懂要问,不可蛮干。否 Chemical experiments have a certain degree of danger. The key to safety experiments is to carry out experiments in accordance with the operational regulations, and dangers can also become safe. On the contrary, security also becomes insecure.

You must be familiar with the rules of operation, understand the laws of reaction, and don’t know what to ask. no
