化合价是元素的一种性质,是否掌握好化合价,直接关系到能否学好氧化还原反应.一、依据化合价,判断化学反应是否是氧化还原反应
Valence is a property of an element. Whether or not you have a good valence is directly related to whether or not the oxidation-reduction reaction can be learned. First, based on the valence, determine whether the chemical reaction is a redox reaction.
