守恒法是解答化学试题的重要方法,掌握了守恒法就等于掌握了解题的金钥匙。守恒法在解答化学反应原理试题中有重要的应用,下面具体举例分析。1.电子守恒的应用例1银锌碱性蓄电池放电时的反应原理是:Zn+Ag2O+H2O2Ag+Zn(OH)2现用该电池电解含有0.04 mol CuSO4和
Conservation Law is an important way to answer chemistry questions, mastered the conservation law is equal to grasp the golden key to solving problems. Conservation Law in the answer to the principle of chemical reaction has important applications, the following specific examples. 1. The application of electron conservation Example 1 The reaction principle of silver-zinc alkaline storage battery discharge is: Zn + Ag2O + H2O 2Ag + Zn (OH) 2 Now the battery electrolysis contains 0.04 mol CuSO4 and
