1、第一章开启化学之门第一节练习与实践1.88g。2.如 1952 年冬天,伦敦的烟雾事件。1955 年日本的四日市的空气污染事件。1952 年美国洛杉矶的光化学烟雾的污染事件。我国近年来福建、浙江沿海的赤潮事件。3.如大气污染、全球气候变暖、南极上空臭氧空洞的出现,向人们提出了减少二氧化碳气体的排放、消除大气污染物等课题。用化学的方法对大气进行检测和污染防治,回收处理生产的大量垃圾,变废为宝等都是化学工作者的重要任务。第二节练习与实践1.C 2.D 3.D 第三节练习与实践l.(1)试剂瓶标签向手心,沿略倾斜的试管缓缓倒人,瓶口紧靠试管口。(2)根据试管的大小折叠纸槽,将药品放在纸槽上,水平送入
2、试管中,竖起试管,抽出纸槽。也可以用药匙代替纸槽。(3)用试管夹夹在离试管口约l3 处,试管口略向下倾斜,先均匀预热,后固定在药品部位加热。(4)废液倒在废液缸中,废渣倒在指定的容器中,不能随意丢弃。2.见 P73 表3.猜想:(1)铝能导电;(2)铝能与氧气反应;(3)铝能与食醋反应。实验设计:(1)将打磨好的铝片连接一节干电池和电珠;(2)在酒精灯上加热铝片;(3)将一小片铝片放人食醋中。实验现象:(1)电珠亮了;精品w o r d 学习资料 可编辑资料-精心整理-欢迎下载-第 1 页,共 18 页(2)铝片表面光泽度下降,变白;(3)现象不明显,若加热,则有少量的气泡产生。结论:(1)铝
3、能导电:(2)铝与氧气反应生成白色的氧化铝,但没有像镁带与氧气反应那样剧烈;(3)铝几乎不能与冷的食醋反应,加热则有少量气泡产生,不如镁带与食醋反应现象明显。本章作业1.C 2.A 3.A 4.不一定。(1)固态二氧化碳受热升华变成气态二氧化碳,这种变化是物理变化。(2)碳酸氢铵受热分解成氨气、水蒸气、二氧化碳,生成了新物质,这是化学变化。5.物理性质有:无色透明、具有特殊的气味,易挥发,易溶解碘等物质。化学性质是:能与氧气反应生成水和二氧化碳。6.变黑上下浮动,像跳舞一样。7.(略)第二章我们身边的物质第一节练习与实践1.A 2.C 3.(略)4.(1)红磷的用量不同,所观察到的现象不同。红
4、磷不足:进入瓶中液体的体积不到1 5;原因是红磷没有将瓶中的氧气耗尽。红磷过量:瓶中进入液体的体积大约为15;红磷将瓶中的氧气耗尽了。(2)(略)5.氮气,78;氧气,2l。3.36。6.水蒸气;红磷燃烧消耗了瓶中的氧气,导致瓶中气压减小;高山上氧气含量较低,携带氧气瓶可补充供呼吸的氧气。精品w o r d 学习资料 可编辑资料-精心整理-欢迎下载-第 2 页,共 18 页文档编码:CV9A5L9O10I7 HJ4B6Q6V6E10 ZL4Q5R6W10O9文档编码:CV9A5L9O10I7 HJ4B6Q6V6E10 ZL4Q5R6W10O9文档编码:CV9A5L9O10I7 HJ4B6Q6V
