2、燃烧3 Fe+2 O2 点燃 Fe3O4铁在空气中不能燃烧，而铁粉可以在空气中燃烧。铁在氧气中 剧烈燃烧，火星四射；生成黑色固体；放出大量的热瓶底要放少量水或细沙，防止生成的固体物质溅落下来，炸裂瓶底。6 镁在空气中燃烧2 Mg+O2点燃 2 MgO 空气中：发出耀眼的白光，放出热量，生成白色固体剧烈燃烧，发出 耀眼白光，生成白烟，放出大量的热（用作照明弹）7 氢气在空气中燃烧2 H2+O2点燃 2 H2O 氢气在空气中燃烧 淡蓝色火焰；8 碳在 空气中不充分燃烧2 C+O2(不足)点燃 2 CO 在空气中保持红热发出白光并且发热，碳消失，生成无色无味的气体，将它导出，发现可以燃烧，生成无色无

3、味的气体，能使澄清石灰水变浑浊9 一氧 化碳在空气中燃烧2 CO+O2点燃 2 CO2发出蓝色的火焰，放热，澄清石灰水变浑浊。10 二氧 化碳通过灼热碳层C+CO2高温2CO（吸热反应）11 生石灰化成熟石灰CaO+H2O=Ca(OH)2（用作食品干燥剂）放出大量的热12 二氧化碳溶于水（二氧化 碳通入紫色石蕊试液）CO2+H2O=H2CO3石蕊 试 液 由紫 色 变 成红色。水变酸性,生成碳酸,颜色没变化,基本上没什么现象,就是冒气泡,应用于 常喝的汽水13 铜在空气中受热2Cu+O22CuO 铜丝变黑。文档编码:CC8S2V9J7X1 HU10X9N2E8V10 ZB6H5Y3K9G1文档
