硫化氢燃烧时,氧气和硫化氢的相对用量不同,发生的反应就不同,气体体积变化也不同,分述如下: (1)当硫化氢不完全燃烧时,化学方程式为:
When hydrogen sulphide is burned, the relative amounts of oxygen and hydrogen sulphide are different, the reactions that occur are different, and the gas volume changes are also different and are described as follows: (1) When hydrogen sulphide is incompletely burned, the chemical equation is:
