(7)气体反应定律和分子说: 1804—1808年间,法国化学家盖·吕萨克研究许多气体物质的反应,他发现在同样温度和压力下,参加反应的各气体的体积和反应生成物气体的体积,互成简单的整数比,为什么气体间的反应会有这样的关系呢?盖·吕萨克解释说:这是因为在同温同压下,同体积的各种气体含有相同数目的原子(他认为单质的原子是简单原子,化合物是复杂原子)。但是这种说 (7) The Law of Gas Reactions and Molecules: During 1804-1808, the French chemist Guy Lusak studied the reaction of many gaseous substances. He found that at the same temperature and pressure, the volumes of the gases participating in the reaction and the reaction products Gas volume, into a simple integer ratio, why the gas reaction will have such a relationship? Guy Lussak explained: This is because at the same temperature and pressure, with the same volume of gas contains the same number (He thinks the elementary atoms are simple atoms and the compounds are complex atoms). But that’s it
