1、近五年北京中考化學(xué)方程式總結(jié)
溫馨提示:本書對(duì)本地區(qū)近五年中考化學(xué)反應(yīng)“立體化”的盤點(diǎn)是正確書寫化學(xué)方程式的有效方法,即在書寫化學(xué)方程式時(shí)不要只機(jī)械地記憶化學(xué)符號(hào),而是聯(lián)想該反應(yīng)的“實(shí)驗(yàn)現(xiàn)象”“反應(yīng)原理”“反應(yīng)的應(yīng)用”“基本反應(yīng)類型”等與之相關(guān)的內(nèi)容,多方位、多角度地對(duì)每個(gè)化學(xué)反應(yīng)進(jìn)行立體整合,尤其是每一個(gè)反應(yīng)的實(shí)際應(yīng)用,考查較為突出。為了便于比較,下面按分類總結(jié)如下:
