10、国的化学家 门捷列夫发现元素周期律和元素周期表。物质的种类繁多(达2000多万种),但组成它们的基本成分一一元素只有100多种。水、氧气、二氧化碳的一个共同点:都含有氧元素。4、我国的某些化学工艺像造纸、制火药、烧瓷器,发明很早,对世界文明作出过巨大贡献。5、用高分子薄膜做的鸟笼:隔水、透气6、用纳米技术制造出具有特定功能的产品(直径 6mm的尼龙绳能吊起2t的汽车) (1nm=10-9m)第一章走进化学世界课题1物质的变化和性质考点要求:认识化学变化的基本特征;理解反应现象和本质之间的联系考点一、物质的变化1-概念:物理变化一一没有生成其它物质的变化。例 :石蜡熔化、水结成冰、汽油挥发 化学

11、变化一一有其它物质生成的变化例:煤燃烧、铁生锈、食物腐败、呼吸2、判断变化依据:是否有其它( 新)物质生成。 有则是化学变化,无则是物理变化3、相互关系:常常伴随发生,有化学变化一定有物理变化,有物理变化不一定有化学变化。4、化学变化伴随现象:放热、吸热、发光、变色、放出气体和生成沉淀。考点二、物质的性质物理性质:物质不需要化学变化就表现出的性质。包括:颜色、状态、气味、熔点、沸点、 密度、硬度、溶解性、挥发性、延展性、导电性、吸水性、吸附性等。化学性质:物质在化学变化中表现出来的性质。可燃性、氧化性、还原性、活泼性、稳定性、腐蚀性、毒性、金属活动性等。它们的区别是:物理性质在静止状态中就能表

12、现出来,而物质的化学性质则要在物质运动状态中才能表现出来三、物理变化、化学变化、物理性质、化学性质之间的区别与联系。联系:在变化语句中加“能”或“可以”或“易”“会”“难于”等词语,变成了相应的性质。物理变化化学变化概念没有生成其他物质的变化生成其他物质的变化伴随现象物质的形状、状态等发生变化常伴随有放热、发光、变色,放出 气体、生成沉淀等本质区别变化时是否有其他物质生成实例石蜡熔化、水结成冰、汽油挥发煤燃烧、铁生锈、食物腐败、呼吸Learn Genera Se ceay on "tw i to earn a" sengthe nig fu Ccnsc o esses&qu

23、3、物理性质:白色的固体,密度比水小,质软结论:燃烧前:蜡烛通常为黄白色的固体,密度比水小,不溶于水燃烧时: 蜡烛发出黄白色的火焰,放热、发光,蜡烛逐渐变短,受热时熔化,冷却后又凝固。 木条处于外焰的部分最先变黑,外焰温度最高。烧杯内壁有水雾出现,说明蜡烛燃烧生成了水,其中含有H元素;蜡烛燃烧后还生成CO2,该气体能使澄清石灰水变浑浊,说明蜡烛中含有 C元素。 白瓷板上有黑色粉末出现,更说明蜡烛中含有C元素。燃烧后:有一股白烟,能重新燃烧。说明蜡烛燃烧是蜡烛气化后的蜡烛蒸气被点燃。实验探究步骤观察物质的性质、变化、现象结论、解释1.观察蜡烛的制作材料烛芯棉线、外壳石蜡由石蜡制成2.点燃前观察蜡

24、烛的颜色、 形态、形状乳白色固态圆柱状颜色:乳白色状态:固态用小刀切下一块石蜡, 投入水中浮在水上,难溶于水,硬度小密度比水小,硬度小,难溶于水3.点 燃用火柴点燃蜡烛,观察 蜡烛火焰火焰分为焰心、内焰、外焰三 层,第二层最明亮,内层暗石蜡具有可燃性,其火焰分为焰心、 内焰、外焰三层,第二层最亮,内层暗取一根火柴,迅速平放火柴杆接触外焰部分先变黑外层温度最高,加热用外层火焰Learn Genera Se ceay on "tw i to earn a" se ngthe nig fu Ccnsc o esses" mpora nt spe ec cu_d astr

36、气的玻璃片上有水珠人呼出气体中含有较 多的水蒸气3、鉴别氧气和二氧化碳:方法:用燃着的木条分别伸入瓶内,使之燃得更旺的是氧气,使之立即熄灭的是二氧化碳;方法:分别倒入澄清的石灰水,使之变浑浊的是二氧化碳,使之无明显变化的是氧气。三、实验探究的方法:A、提出科学问题; 日 假想和猜测; C、制定计划;D 、进行实验;E、收集证据;F 、解释与结论; G、反思与评价; H、表达与交流。四、化学学习的特点:ctiveofeducation.Thisrequires thatt heOrganizationLearn GeneralSe cretaryon"tw oto learn a&qu
