探讨学生化学会考计算题方法选用适宜的办法解核算题，不光能够缩短解题的时刻，还有助于减小核算进程中的运算量，尽可能地下降运算进程中犯错的时机。而化学核算往往逃不过“三大守恒”规律，既原子守恒（质量守恒）、电子得失总数守恒、电荷守恒。Selection of appropriate solve accounting problem, not only can shorten the solving time computation, and help reduce the accounting process, as far as possible mistakes in the process of reduced operation time. Chemical calculation is often to escape the three conservation rules, both atomic conservation ( mass conservation ), the total number of electronic and conserv
