离子方程式的书写： 第一步：写。写出化学方程式 第二步：拆。易溶于水、易电离的物质拆成离子形式；难溶(如CaCO3、BaCO3、BaSO4、AgCl、AgBr、AgI、Mg(OH)2、Al(OH)3、Fe(OH)2、Fe(OH)3、Cu(OH)2等)，难电离(H2CO3、H2S、CH3COOH、HClO、H2SO3、NH3·H2O、H2O等)，气体(CO2、SO2、NH3、Cl2、O2、H2等)，氧化物(Na2O、MgO、Al2O3等)不拆 第三步：删。删去前后都有的离子 第四步：查。检查前后原子个数，电荷是否守恒 离子共存问题判断： ⑵ 是否产生沉淀(如：Ba2+和SO42-，Fe2+和OH-)； ⑵是否生成弱电解质(如：NH4+和OH-，H+和CH3COO-) ⑶是否生成气体(如：H+和CO32-，H+和SO32-) ⑷是否发生氧化还原反应(如：H+、NO3-和Fe2+/I-，Fe3+和I-) 5、放热反应和吸热反应 化学反应一定伴随着能量变化。 放热反应：反应物总能量大于生成物总能量的反应 常见的放热反应：燃烧，酸碱中和，活泼金属与酸发生的置换反应 吸热反应：反应物总能量小于生成物总能量的反应 常见的吸热反应：Ba(OH)2·8H2O和NH4Cl的反应，灼热的碳和二氧化碳的反应C、CO、H2还原CuO 6、各物理量之间的转化公式和推论 ⑴微粒数目和物质的量：n==N / N A，N==nN A ⑵物质的量和质量：n==m / M，m==nM ⑶对于气体，有如下重要公式 a、气体摩尔体积和物质的量：n==V / V m，V==nV m 标准状况下：V m=22.4L/mol b、阿伏加德罗定律：同温同压下V(A) / V(B) == n(A) / n(B) == N(A) / N(B) ⑷物质的量浓度与物质的量关系 (对于溶液)物质的量浓度与物质的量C==n / V，n==CV 7、配置一定物质的量浓度的溶液 ①计算：固体的质量或稀溶液的体积 ②称量：天平称量固体，量筒或滴定管量取液体(准确量取)
