箭头推或电子推是描述有机化学反应机理的技术，它是由鲁滨孙罗伯特爵士首次开发的，在使用箭头推动时，“弯曲箭头”或“卷曲箭头”是在化学反应过程中的结构公式叠加，以显示反应机理。箭头说明电子的运动是债券betweenatoms破裂和形成。箭推也用来描述正负电荷分布在有机moleculesthrough共振。然而要记住，重要...
An unbalanced chemical reaction can give us information about the molecules that are involved in that reaction, however, it can not gives us the proper numbers of molecules that are involved. To get the number of molecules we need a balanced equation. Theref...
