实验室制取气体的装置由发生装置和收集装置两部分组成。制取气体的发生装置的选择是由反应物的状态与反应条件来决定。根据反应物的状态和反应条件的不同，初中化学中制取气体的反应有两种情况，与此时应，有两类气体的发生装置。气体发生装置如图1。该装置适用于反应物都为固
The device for preparing gas in the laboratory consists of two parts: the generating device and the collecting device. The choice of the gas generation device is determined by the state of the reactants and the reaction conditions. Depending on the state of the reactants and the reaction conditions, there are two kinds of reactions for the preparation of gas in junior high school chemistry. There are two kinds of gas generating devices. The gas generating device is shown in Figure 1. The device is suitable for all reactants
