问题 填空题

现有木炭、硫粉、氧气、锌、二氧化锰、氯酸钾、高锰酸钾、过氧化氢、石灰石、水、稀盐酸等物质,请从中选择适当的物质,用化学方程式表达下列,并在后面的括号内注明反应类型.

①实验室制取氧气的反应______(______);

②实验室制取氢气的反应______(______);

③有刺激性气味气体产生的反应______(______);

④生成能使澄清石灰水变浑浊气体的反应______.

答案

①实验室可采用分解过氧化氢溶液或加热高锰酸钾的方法来制取氧气,如过氧化氢在二氧化锰的催化作用下生成水和氧气,反应的化学方程式为:2H2O2

 MnO2 
.
 
2H2O+O2↑;该反应符合“一变多”的特征,属于分解反应.

②实验室常采用锌和稀硫酸反应制取氢气,反应的化学方程式为:Zn+H2SO4═ZnSO4+H2↑;该反应是一种单质和一种化合物反应生成另一种单质和另一种化合物的反应,属于置换反应.

③硫粉在氧气中燃烧生成有刺激性气味气体二氧化硫,反应的化学方程式为:S+O2

 点燃 
.
 
SO2;该反应符合“多变一”的特征,属于化合反应.

④碳在氧气中燃烧生成能使澄清石灰水变浑浊气体,反应的化学方程式为:C+O2

 点燃 
.
 
CO2(合理均可).

故答案为:①2H2O2

 MnO2 
.
 
2H2O+O2↑;分解反应;②Zn+H2SO4═ZnSO4+H2↑;置换反应;③S+O2
 点燃 
.
 
SO2;化合反应;④C+O2
 点燃 
.
 
CO2(合理均可).

阅读理解

Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires—not that you cannot satisfy your tastes but that you don't have enough tastes.

Real riches consist of well-developed and hearty capacities (能力)  to enjoy life.  Most people are already swamped(淹没) with things. They eat, wear, go and talk too much. They live in too big a house with too many rooms, yet their house of life is a hut.

Your house of life ought to be a mansion (豪宅) , a royal palace.  Every new taste, every additional interest, every fresh enthusiasm adds a room.  Here are several rooms your house of life should have.

Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of ham and eggs when you're hungry.

Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but who likes a library.

Music like Mozart's and Bach's shouldn't be absent. Real riches are of the spirit. And when you've brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills.

Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the had days, if you could, and did, play a bit.

Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding.
