题目:

(2013江西)物质王国举行一场趣味篮球赛。某队由铁、二氧化碳、硫酸、氢氧化钙、氯化铜五名“队员”组成,比赛中,由氯化铜“队员”发球,“队员”间传接球,最后由D位置“队员”投篮进球完成一次有效进攻。场上“队员”位置及传球路线如图所示。

(1)已知D位置上投篮的“队员”是个灭火“能手”,则D位置“队员”代表的物质是        

(2)B位置“队员”所代表物质的一种用途是        

(3)写出连线④代表的物质间发生反应的化学方程式                                         ;连线①代表的物质间发生化学反应的基本类型是        反应。

答案:

(1) CO2 (或二氧化碳)(2分) (2)金属除锈(或生产化肥、农药、火药、燃料等〉(2分)

(3) CO2 +Ca(OH)2 =CaCO3↓+H2O  (2分);置换(2分)

题目分析:首先根据“D位置上投篮的‘队员’是个灭火能手可知D为二氧化碳,根据C、D 间能反应,在五种物质中能与二氧化碳反应的物质是氢氧化钙,即C是氢氧化钙,剩余二种物质中能与氢氧化钙反应的物质是硫酸,所以B是硫酸.最后剩下A为铁.

A man once said how useless it was to put advertisements in the newspaper.

“Last week, ” he said,  “my umbrella was stolen from a London church. As

it was a present,  I spent twice its worth in advertising,  but didn’t get it back. ”

“How did you write your advertisement? ” asked one of the listeners,  a merchant.

  “Here it is, ” said the man,  taking out of his pocket a slip cut from a newspaper. The other man took it and read,  “Lost from the City Church last Sunday evening,  a black silk umbrella. The gentleman who finds it will receive ten shillings on leaving it at No. 10 Broad Street. ”

“Now, ” said the merchant,  “I often advertise,  and find that it pays me well. But the way in which an advertisement is expressed is of extreme importance. Let us try for your umbrella again,  and if it fails,  I’ll buy you a new one. ”

  The merchant then took a slip of paper out of his pocket and wrote:  “If the man who was seen to take an umbrella from the City Church last Sunday evening doesn’t wish to get into trouble,  he will return the umbrella to No. 10 Broad Street. He is well known. ”

  This appeared in the newspaper,  and on the following morning,  the man was astonished when he opened the front door. In the doorway lay at least twelve umbrellas of all sizes and colors,  and his own was among them.
