位于金属活动性顺序 (H)前面的金属称为活泼金属 ,它们都能跟稀盐酸或稀硫酸等非氧化性酸发生置换反应放出氢气。解此类题时 ,如果运用常规解法 ,费时费力。现把速解这类计算题的规律作一归纳 ,供大家参考。速解规律一 等质量的多种活泼金属与非氧化性酸反应 ,若金属过量而酸
Metals in front of the metal activity sequence (H) are called active metals and they can all react with non-oxidizing acids such as dilute hydrochloric acid or dilute sulfuric acid to release hydrogen. When solving such questions, it is time-consuming and laborious to apply conventional solutions. The law of quick calculations of such calculations is summarized for your reference. Fast-acting laws such as the quality of a variety of reactive metals and non-oxidizing acid reaction, if the metal is too much acid
