     Marianne, a schoolgirl, was learning to play the piano, and day after day her father stood behind her
as she practiced.
      How very patient and loving 1 was, and how cleverly he showed Marianne  2 to play some difficult
pieces! She was making progress, and that was excellent.
     And there, almost last in the big chair, sat Wolfgang, her four-year-old 3 , who never had to be told
to 4 quiet when Marianne was  5 .
     One evening at sundown the father patted Marianne's shoulder, 6 she had dome very well. At the
moment Wolfgang climbed on his father's knee and begged to play the pretty 7   Marianne had now
mastered.
     What a 8 that was! Picking his baby son, the father 9 , tapped the nose and said, "Look at your
small 10 . You must wait, like man. You must wait!"
      There was no end, and Marianne had to tell her mother about Wolfgang wanting to 11 one of the
classics. After  12 Marianne helped clear away the dishes when the father lit his pipe (烟斗).
      But the pipe went out. He was on his feet.
      "Listen! Marianne is playing that piece 13 than ever!"
      But Marianne was washing pots in the kitchen.
      His wife following, he went upstairs, the lamp in one hand, his pipe in 14 ,he pushed open the door,
and there was little Wolfgang  15 in the darkness.
      "I love it so!" whispered the child.
      It was the beginning of Mozart's life of music.

填空题

(14分)已知:通常状况下甲、乙、丙、丁为气体单质,A、B、C、D、E、F、G、H等为化合物,其中A、B、E、G均为气体,C为常见液体。反应①、②、③是工业制H的重要化工反应,反应④是重要的实验室制取气体的反应。有关的转化关系如下图所示(反应条件均已略去)。请回答下列问题:

(1)反应④的化学方程式为                                             

(2)B和E在一定条件下可发生反应,该反应具有实际意义,可消除E对环境的污染,该反应中氧化产物与还原产物的物质的量之比为                  

(3)在恒温恒压容器中加入一定量B,催化条件下发生反应B乙+丁(未配平),达平衡后再加少量B,则平衡       移动(填“正向”、 “逆向”或“不”),重新平衡后与原平衡相比,B的转化率       (填“增大”、 “减小”或“不变”)。

(4)常温下,物质的量浓度相同的A、B、D三者的水溶液,由水电离出的c(OH)大小顺序是(用A、B、D表示)                                            

(5)惰性电极电解A和D的混合溶液,可生成丁单质和一种二元化合物M(与甲、乙所含元素相同),M为三角锥形分子,该反应的方程式为                      。在碱性溶液中M与NaClO2(亚氯酸钠)按物质的量之比1∶6恰好反应可生成化合物B和消毒剂ClO2气体,该反应的离子方程式为                                   

(6)将Fe、FeO、Fe3O4的混合物二等分,其中一份加入1mol/L的A溶液100 mL,恰好使混合物全部溶解,且放出336mL(标况下)的气体,向所得溶液中加入KSCN溶液,溶液不变红;另一份混合物加入1 mol/ L 的H溶液,也恰好使混合物全部溶解,且向所得溶液中加入KSCN溶液,溶液也不变红,则所加入的H溶液的体积是        mL。
