1.选择题(共4题)

1.某兴趣小组的同学在探究活泼金属单质与酸反应的实验时,设计了两个方案进行实验.

方案一:设计了甲乙两个装置,在室温条件下进行如下图甲乙所示实验(反应过程中装置气密性良好).已知:试管内的镁条和铁片表面均被打磨光亮洁净,且形状、大小均相同;同时加入两支试管中的稀盐酸质量和质量分数均相等(实验中镁条和铁片均过量)

方案二:如图丙,将等质量光亮洁净,形状厚薄相同的镁条和铁片分别放入左、右试管中,加入等质量、等质量分数的稀盐酸,充分反应后,冷却到室温,金属均有剩余,(U型管内为水,初始液面相平,反应过程中装置气密性良好)

查阅资料得知

①镁,铁的活动性均在H之前并且镁比铁活泼.

②相同条件下,相同时间内金属的活动性越强,与酸反应越剧烈.

2.如图所示,在小烧杯A中装入30mL蒸馏水,再滴入3滴酚酞,在小烧杯B中装入30mL浓氨水.

用一大烧杯把A、B两个烧杯罩在一起,过一段时间后看到的现象是{#blank#}1{#/blank#},该实验说明{#blank#}2{#/blank#}.

一些同学对上述结论有不同看法,主要有以下两种猜测:

第一种:A烧杯中的蒸馏水使酚酞试液变红;

第二种:B烧杯中的浓氨水挥发出氨气,扩散到A烧

杯的溶液中使酚酞试液变红.

①你认为{#blank#}3{#/blank#}猜测正确;

②为证明这两种猜测,现设计如下的实验:(请填空)

实验内容和方法

现象

结论

用洁净的小烧杯取20mL水,滴入2~3滴酚酞试液,观察现象

不变色

水{#blank#}4{#/blank#}(填“能”或“不能”)使酚酞变色

取一张滤纸,滴上酚酞试液,待晾干后,放在装有浓氨水的试剂瓶上方

酚酞不变色

氨气{#blank#}5{#/blank#}使酚酞变色(填“能”或“不能”)

将少量氨气通入含有酚酞试液的蒸馏水中

溶液变成

{#blank#}6{#/blank#}色

氨气溶解在水中形成氨水能使酚酞变色

③上述探究在设计上采用了{#blank#}7{#/blank#}实验,证明出不同的分子,其{#blank#}8{#/blank#}性质不同(填“化学”或“物理”).

3.按如图所示装置进行实验并完成下列实验报告:

实验步骤

现象

分析出现该现象的原因

在烧杯中放入几块冰糖后倒入100mL水,放一根筷子,在水面处画一道

线做记号

{#blank#}1{#/blank#}

{#blank#}2{#/blank#}

用筷子不断搅拌

取出筷子后,发现液面

{#blank#}3{#/blank#}于所作标志线

{#blank#}4{#/blank#}

实验目的:{#blank#}5{#/blank#}

实验器材:烧杯、筷子、水、冰糖

你认为上述实验中是否有不妥之处?{#blank#}6{#/blank#}.如有请改正{#blank#}7{#/blank#}.(如没有不妥之处该空不填)

4.课堂上老师按图I装置进行分子运动实验时同学们闻到了一股难闻的刺激性气味,课后在老师的指导下,同学们对原实验装置进行了改进,装置如图II所示.
