To Whom It May Concern:

On March 5, 2012 , I bought a Perfect Muffin Kit(松饼粉 ) from your store at Midfield Shopping Center. The cashier who assisted me was George. George was very friendly and told me that the Perfect Muffin Kit would live up to the guarantee on the box: “Perfect Muffins Every Time!”.

Unfortunately, this product did not live up to what it promised . The muffins I made were far from perfect . I followed the directions in the package very carefully . First , I removed the bag of mix from the box. Then , I poured it into a bowl. Next, I added the correct amount of water to the mix and stirred it. According to the directions, after stirring the mixture , I added half a cup of dried prapes, nuts , berries, or another favorite ingredient(配料 ) . My favorite ingredient happens to be hot sauce (沙司 ). I find that a bit of hot sauce makes pizza and soup taste very delicious. So, continuing to follow the directions, I added half a cup of hot sauce to the mix and stirred it. Finally, I poured the mix into muffin tins and baked it in the baker at 350 degrees for exactly 20 minutes.

When the muffins finished baking, I was very excited to eat the “Perfect Muffins” as promised on the box. You can imagine my disappointment when, upon tasting the muffins, I discovered that they were not perfect. These muffins were , in fact , absolutely terrible. Not even my dog was interested in eating these supposedly “perfect”muffins.

I would appreciate a full refund(退款 ) of $3.99 for this product as soon as possible. Enclosed are the receipt, the empty box, and one of the un-perfect muffins so that you can experience it for yourself . Thank you for your attention to this matter.

Sincerely ,

Michelle Bauer

(II)(14分)

工业上制取硝酸铵的流程图如下,请回答下列问题:

(1)1909年化学家哈伯在实验室首次合成了氨。2007年化学家格哈德·埃特尔在哈伯研究所证实了氢气与氮气在固体催化剂表面合成氨的反应过程,示意如下:

分别表示N2、H2、NH3。图⑤表示生成的NH3离开催化剂表面,图②和图③的含义分别是                                          

(2)在合成氨的设备(合成塔)中,设置热交换器的目的是                           

在合成硝酸的吸收塔中通入空气的目的是                                  

(3)生产硝酸的过程中常会产生一些氮的氧化物,可用如下两种方法处理:

碱液吸收法:NO+NO2+2NaOH===2NaNO2+H2O

NH3还原法:8NH3+6NO2 7N2+12H2O(NO也有类似的反应)

请从绿色化学的角度分析两种方法的优劣:                               

(4)某化肥厂用NH3制备NH4NO3。已知:由NH3制NO的产率是96%、NO制HNO3的产率是92%,则制HNO3所用去的NH3的质量占总耗NH3质量(不考虑其它损耗)的       %。

(5)硝酸铵是一种常用的氮肥,在贮存和使用该化肥时,把应注意的事项及理由填入下表。
