    An old man lived alone in his old house. He hardly ever came out. He wouldn't communicate with others.

    One day, a little boy selling magazines knocked at the man's door. The door slowly opened. "Uh, sir, would

you like to buy a magazine?" The old man just stared (盯着) at the boy. The boy saw lots of dog sculptures

(雕塑品)on the table. "Do you collect dogs?" the boy asked. "Yes, they are all my family." Hearing this, the

boy understood and felt sorry for him." I have a magazine here about dogs. It's perfect for you." The old man

was ready to close the door and said, "No, I don't need any magazines."

    The boy suddenly had an idea. He had a dog sculpture, which did not mean much to him. After a while, the

boy returned with a box. The old man shouted this time,"I told you no magazines!" "I bring you a gift." The

boy opened the box and handed him the sculpture. The man got surprised because no one had given him a gift.

From that day on, the old man started coming out of his house. He and the boy became friends. The boy even

brought his pet dog to visit the old man every week.

根据短文内容,回答下列问题。

某温度下,体积一定的密闭容器中进行反应:N2(g)+3H2(g)═2NH3(g)△H<0.下列分析正确的是(  )

A.平衡后加入N2,该反应的△H增大,平衡常数不变

B.若平衡后升高温度,NH3的体积分数增大,反应的平衡常数也增大

C.若反应前充入等物质的量的N2与H2,则在反应过程中,N2的体积分数始终为50%

D.若反应前充入的N2与H2物质的量相等,达平衡时N2的转化率比H2

(7分)某兴趣小组根据实验室提供的仪器和药品进行了氧气的制备实验。

(1)甲同学选用如右图所示的装置制取氧气。

①写出仪器A的名称:     ▲      

②甲同学应选取的试剂是MnO2  ▲  (填化学式),MnO2固体在该反应中起      ▲     作用。

③除用排水法外,甲同学还可选择  ▲  法收集氧气。

(2)乙同学称取一定质量KMnO4放在大试管中,将温度控制在250℃加热制取O2,该反

应的反应表达式为       ▲      (用化学式表示)。实验结束时,乙同学发现收集到的O2大于理论产量,针对这一现象,同学们进行了如下探究:

【提出猜想】猜想Ⅰ:反应生成的MnO2分解放出O2

猜想Ⅱ:反应生成的K2MnO4分解放出O2

做出上述猜想的理由是             ▲                

【实验验证】同学们分为两组,分别进行以下实验:

①第一组同学取一定质量的MnO2,在250℃条件下加热一段时间,冷却后测得MnO2的质量不变。则猜想     ▲      错误。

②第二组同学取K2MnO4置于试管中,在250℃条件下加热,没有用测定K2MnO4质量的方法,而是用了另一种实验方法得出了猜想Ⅱ是正确的。该组同学选择的实验方法是

               ▲                。
