问题描述:

(1)写出下列化学方程式,1,氢气和氧气点燃生成水 2,硫在氧气中燃烧
3,镁与氧化铜反应生成氧化镁与铜 配平下列化学式 (1)——C2H2+_____O2点燃_____CO2+____H2O (2)________Ca(oh)2+________CaSO4+_______h2o (3)______C2H5OH+______O2点燃_____CO2+______H2 (4) ______Fe2O3+____CO=_____Fe+_______CO2 (5)______CO2+______NaOH=______Na2CO3+_______H2O (6)________Fe+_____H2O=______Fe3O4+_____H2↑

(1) 1.2H2 + O2 =点燃=2H2O2.S+ O2 =点燃= SO23.Mg + CuO =加热= MgO + Cu(2) 1) 2C2H2+___5__O2=点燃=___4__CO2+__2__H2O(2)___1_Ca(OH)2+____1_ H2SO4=1CaSO4+___2_H2O (3)___1___C2H5OH+____3__O2=点燃=___2__CO...
