My parents always say, “   42  hard and the world is yours.” They are never without a   43  word of advice or a bit of encouragement when life gets tough.
My parents always   44   me to go to college. However, when I    45  at 16 years old that I’d rather get married to a man than go to college, they    46   stopped telling me they loved me and I could anything I wanted to.   47  , they persuaded me. I graduated from high school and currently   48  the University of Oklahoma studying medicine. I want to make the   49  a better place to live in.
Every time I call home to tell them about a   50  I received in Chemistry Lab or Microeconomics or whichever    51  it is that I’m working hardest for at the moment, they tell me how   52  of me they are. I know there are college kids out there that have no one to call home when they an “A” on a project and I feel incredibly   53  to have my parents.
Don’t get me wrong: We’ve had our share of    54  . I was the angry teenager and they were the awful    55   that wouldn’t let me stay out all night or let me get my tongue pierced(扎洞).But somehow, we   56 to work through those issues. They never   57  loving in me or believing in me.
I   58 everything I am to my parents. Without their   59 love and encouragement, I wouldn’t believe I can change the world. My parents taught me to always   60  for what I believe in. So I’m working toward something really great and can only hope I continue to make them proud.

硝酸工业的基础是氨的催化氧化,在催化剂作用下发生如下反应:

① 4NH3(g)+5O2(g)4NO(g)+6H2O(g)    △H =" —905" kJ/mol    ①主反应

② 4NH3(g)+3O2(g)2N2(g)+6H2O(g)     △H =" —1268" kJ/mol   ②副反应

有关物质产率与温度的关系如甲图。

(1)由反应①②可知反应⑤N2(g) + O2(g)2NO(g)的反应热ΔH=     

(2)由图甲可知工业上氨催化氧化生成 NO时,反应温度最好控制在     

(3)用Fe3O4制备Fe(NO33溶液时,需加过量的稀硝酸,原因一:将Fe4O3中的Fe2+全部转化为Fe3+

原因二:     (用文字和离子方程式说明)。

(4)将NH3通入NaClO溶液中,可生成N2H4,则反应的离子方程式为     

(5)依据反应②可以设计成直接供氨式碱性燃料电池(如乙图所示),则图中A为     (填“正极”或“负极”),电极方程式为
