摘要
依化学反应实质,反应前后各种量守恒。利用守恒关系解题,可以不必纠缠过程的细节,只注意所涉及问题始态和终态的某种守恒关系,建立等式求解。
Working out the problems by conservation relations based on the substance of chemical reaction and the conservation of various qualities before or after the reaction can easily find the solution through equality without getting entangled with the details in the course and with the attention only to certain conservation relations between the starting and ending states.
