问题 填空题

(16分)现有金属单质A、B、C和气体甲、乙、丙及物质D、E、F、G、H,它们之间能发生如下反应(图中有些反应的产物和反应的条件没有全部标出)。

请根据以上信息回答下列问题:

(1)写出下列物质的化学式:A             、B             、C              

             、乙            、H              

(2)写出下列反应的离子方程式:

反应⑤                                                                    

反应⑥                                                                      

答案

(16分)(1)A:Na   B:Al  C:Fe 甲:H2    乙:Cl2  H:Fe(OH)3

(2)反应⑤:2Fe2+ +  Cl==  2Fe3+  + 2 Cl-    反应⑥:Fe3+ + 3OH - ="=" Fe(OH)3↓

本题是无机框图题,关键是找准突破点。金属A的焰色反应是黄色,说明A是钠。钠和水反应生成氢气和氢氧化钠,则D是氢氧化钠,甲是氢气。黄绿色气体应该是氯气,即乙是氯气。所以丙是氯化氢,E是盐酸。能和氢氧化钠反应生成氢气的金属应该是铝,即B是铝。红褐色沉淀H应该是氢氧化铁,所以G是氯化铁,则F是氯化亚铁,所以金属C是铁。

A daughter        to her father about her life and how things were so hard for her. She did not know whether she was going to make it and wanted to give up. She was        fighting and struggling. It seemed that if one problem was solved a new one       .
Her father, a cook, took her to the       . He filled three pots with water and placed each on a high fire. Soon the pots came to a        In one he placed       , in the second eggs, and in the last ground(磨成粉的)coffee beans. He let them sit and boil, without saying a word.
The daughter sucked her teeth and impatiently waited,        what he was doing. In about twenty minutes he        the burners. He        the carrots and eggs out and placed them in a bowl! Then he        the coffee into a cup. Turning to her, he asked, "Darling, what do you see?"
"Carrots, eggs and coffee," she replied.
He brought her closer and asked her to        the carrots. She did and noted that they were soft. He then asked her to take an egg and break it After pulling off the       , she observed the hard-boiled egg. Finally, he asked her to sip(啜饮)the coffee. She smiled as she        its rich aroma(芳香).
"What does it mean, Father?" she asked.
He        that each of them had        the same adversity(厄运), boiling water, but each reacted       . The carrot went in strong, hard, and unrelenting, but after being subjected to the boiling water, it        and became weak. The egg had been       , with its thin outer shell protecting its liquid inside, but after sitting through the boiling water, its inside hardened. The ground coffee beans were unique. After they were in the boiling water, they had        the water.
"Which are you?" he asked his daughter.
When adversity knocks on your door, how do you       ? Are you a carrot, an egg, or a coffee bean?
