所谓配等法 ,就是通过改动化学式前面的化学计量数或化学式右下角的原子个数 ,从而使题给等量关系 (或根据解题需要自行设定的等量关系 )在化学式上得到直观的体现 ,然后再利用变形后的化学式去进行相关的计算 .它在解化学式计算的客观题时十分简捷有效 .例 1 在质量相等的二?
The so-called equalization method is to change the chemical formula in front of the chemical formula or the number of atoms in the lower right corner of the chemical formula so that the question can be intuitively expressed in terms of chemical formulae (or an equivalent relationship based on the need to solve the problem). Embodied, and then use the chemical formula after deformation to carry out the relevant calculation. It is very simple and effective in solving the objective problem of chemical formula calculation. Example 1 in the same quality of two?
