问题:

(1)煤气的主要成分是CO和H2的混合气体,它由煤炭与水蒸气在高温下反应制得,故又称水煤气。写出制取水煤气的主要化学方程式_________,该反应是_________反应(填“吸热”或“放热”)。

(2)1molC、1molCO分别按下式反应放热情况如下:

反应a:  C(s)+ 1/2 O2(g)= CO(g)   放热110.5kJ     

反应b:  CO(g)+ 1/2 O2(g)= CO2(g)  放热283 kJ

反应c:  C(s)+ O2(g)=CO2(g)    放热393.5kJ

相同质量的碳完全燃烧比不完全燃烧放热_________(填“多”或“少”),若1mol碳经过反应a、b全部转化为CO2,则总放热_______393.5KJ(填“>”“<”或“=”)。若1mol碳燃烧实际放热为336.9KJ,则发生不完全燃烧的碳为_________mol。

考点:吸热反应、放热反应焓变、反应热化学反应热的计算

Ⅲ. 第一节(共20小题; 每小题2分, 满分40分))阅读下列短文, 从每题所给的选项(A、B、C、D)中,选出最佳选项,并在答题卷上将该选项标号涂黑。

“Few things help an individual more than to place responsibility upon him, and let him know that you trust him.” These words are from the black American educator, Booker Washington. He was saying that, “If you want people to grow up, you have to stop treating them like children.”

In America, families are close but children are encouraged to be independent, to make their own decisions, even at a very early age. It’s not unusual for a child of seven to be given an allowance (津贴) every week. The child is encouraged to save some of the money but he or she can spend it on whatever they choose, for example, buying clothes, school supplies or CDs. Some teenagers even have their own credit cards! That’s a big responsibility since even adults are tempted to overspend when they have credit.

From an early age, American children are asked for their opinions and they are included in family decision-making. At the dinner table, teenagers will be listened to on any topic, from politics to buying a new family car or where the family will go on vacation. In this way, teenagers are getting practice in becoming individuals: they are learning how to stand on their own two feet.

Many Chinese young people are becoming almost as interested as American teens in searching for independence. They want to express those qualities that make them unique human beings. You can see this in the way they dress, the music they listen to and the friends they choose. “Super Girl” Li Yuchun caught the imagination of Chinese teenagers on the “Super Girl” television contest. She was not the traditional “nice, young Chinese girl”. With her short, spiky hair and boy-like clothes, she was telling everyone that she was different. She had the courage to be her own person and to stand on her own two feet ... and she won!

There is an old saying, “Everyone should carefully observe which way his heart draws him and then choose that way with all his strength.” If you do this, step by step, over a period of time, you may find that you have become the person you always wanted to be.
