题干

在化学反应中,凡是元素化合价发生改变的反应,称为氧化还原反应.配平这类反应方程式往往采用“化合价升降法”更方便快捷,即反应中元素“化合价升高总数=化合价降低总数”.
例如:□Al+□MnO2═□Al2O3+□Mn,具体配平步骤如下:
①“标变价”:找出化合价发生改变的元素,并标出改变前后的化合价.
4 Al0 +3 Mn+4 O2═2 Al+3 2O3+3 Mn0
②“列变化”:列出改变的价态数.
Al0Al+3 升高3价 Mn+4Mn0 降低4价
③“找倍数”:找出化合价升、降的最小公倍数为3×4=12,从而确定Al、MnO2的系数.
4Al+3MnO2═2Al2O3+3Mn
④“配系数”:再用观察法,配平其它系数.
4Al+3MnO2═2Al2O3+3Mn
