A poor farmer had a  friend who was famous for the wonderful apple trees he grew.

One day, his friend gave the farmer a young apple tree and told him to plant it.  The farmer was pleased with the gift, but he did not know where to plant it.

He was afraid that if he planted the tree near the road, strangers would steal the fruit.  If he planted the tree in one of his fields, his neighbors would come at night and steal some of the apples.  If he planted the tree near his house, his children would take the fruit.  Finally he planted the tree in his wood.  But without sunlight and good soil(土壤), the tree soon died.

Later the friend asked the farmer why he had planted the tree in such a poor place.  “What’s the difference?” the farmer said angrily and then told what he had thought.

“Yes,” said the friend, “but at least someone could have enjoyed the fruit.  Now you not only have robbed everyone of the fruit, but also you have destroyed (毁掉) a good apple tree! ”

(1)发射卫星时可用肼(N2H4)为燃料和二氧化氮做氧化剂,两者反应生成氮气和气态水。

已知: N2(g) + 2O2(g) = 2NO2(g)           △H = 67.7kJ·mol-1

N2H4(g) +O2 (g) = N2(g) +2H2O (g)   △H = -543 kJ·mol-1

H2(g) + F2 (g) = HF (g)          △H = -269 kJ·mol-1

H2(g) +O2(g) = H2O (g)             △H = -242 kJ·mol-1

①肼和NO2反应的热化学方程式为:

_____                                                         

②有人认为若用氟气代替NO2作氧化剂,则反应释放的能量更大,肼和氟气反应的热化学方程式为:                                                          

(2)科学家制造出一种使用固体电解质的燃料电池,其效率更高。一个电极通入空气,另一个电极通入汽油蒸汽。其中固体电解质是掺杂了Y2O3(Y:钇)的ZrO2(Zr:锆) 固体,它在高温下能传导O2离子。以戊烷(C5H12)代表汽油,完成下列问题:

①电池反应方程式为                                                     

②放电时固体电解质里的O2离子的移动方向是向       极移动(填“正”或“负”)
