     Life may not always seem fair, but we can learn to deal with it and make new choices along the way.

     I remember so clearly sitting next to my dad as we drove through the town. I was complaining about

something unfair that had happened to me. Dad looked directly at me and said,"No one ever said life was fair."

I was shocked at his answer. Later on as my marriage had problems even though I tried to save it. I could still

hear"It's not fair" in my heart. Now as I raise two kids alone, try to create new relationships and build a

business, I am forced to face the inevitable (不可避免的) truth every day. Gradually I've found that I have

accepted my dad's wisdom.

     We all will face loss or unexpected changes. But unfairness should not be the only thing in our life. We

choose for ourselves what seems fair by comparing our lives with others', and this can lead us to feel that our

own lives are unfair. People need to ignore what others have and set their own plans. Certainly, there're so many unhappy events in the world and in our lives, and when we deal with them, we try to control as many things as we can. Then, the sense of" it's not fair" often comes when we can't control the things in our lives. So please

put your efforts into the process rather than the result. You should learn that life is unfair, but you can be fair

and learn how to enjoy life.

单项选择题
填空题

氨气是一种重要工作原料,在工农业生产中具有重要的应用。

(1)已知:N2(g)+O2(g)="2NO(g)  " △ H=180.5kJ·mol1

4NH3(g)+5O2(g)=4NO(g)+6H2O(g) △H=-905 kJ·mol1

2H2(g)+O2(g)=2H2O(g)   △H=-483.6kJ·mol1

则N2(g)+3H2(g)=2NH3(g)的△H=_________________________。

(2)工业合成氨气的反应为N2(g)+3H2(g) 2NH3(g)。在一定温度下,将一定量的N2和H2通入到体积为1L的密闭容器中达到平衡后.改变下列条件,能使平衡向正反应方向移动且平衡常数不变的是__________________。

①增大压强   ②增大反应物的浓度   ③使用催化荆   ④降低温度   

( 3 )①实验室常用加热氯化铵固体和氢氧化钙固体的混合物来制取氨气,写出反应的化学方程式                             。实验室还可在        (填一种试剂)中滴加浓氨水的方法快速制取少量氨气。

②常温下氨气极易溶于水,溶液可以导电。氨水中水电离出的c(OH)          107 mol·L-1(填写“>”、“<”或“=”);

③将相同体积、PH之和为14的氨水和盐酸混合后,溶液中离子浓度由大到小的顺序

为                                                          

(4)合成氨的原料氢气是一种新型的绿色能源,具有广阔的发展前景。现用氢氧燃料电池进行图所示实验:(其中a、b均为碳棒)

①氢氧燃料电池具有广阔的发展前景。如下图所示:

右边Cu电极反应式是                          

a电极的电极反应式                         

②工业上生产氢气是将水蒸气通过红热的炭,产生水煤气:

C(s) + H2O(g)  H2(g) + CO(g)  △H =" +131.3" kJ/mol

该反应在低温下不能自发进行的原因是     

A.△H >0

B.温度较低时,△H影响为主

C.△S<0

D.温度较低时,△S影响为主
