“节能减排”，减少全球温室气体排放，意义十分重大。二氧化碳的捕捉与封存是实现温室气体减排的重要途径之一，科学家利用溶液喷淋“捕捉”空气中的。

（1）使用过量溶液吸收，反应的离子方程式为________；若含有3molNaOH的溶液“捕捉”了22．4L气体（标准状况），则所得溶液中钠与碳元素的物料守恒关系式为__________（用离子浓度的关系式表示）。

（2）①以和为原料可合成化肥尿素[]。已知：

①

②

③

试写出和合成尿素和液态水的热化学方程式__________。

②通过反应可转化为，在催化剂作用下CO和反应生成甲醇：某容积可变的密闭容器中充有10molCO与20mol，CO的平衡转化率（a）与温度、压强的关系如下图所示。

A．若A点表示在某时刻达到的平衡状态，此时容器的容积为VL，则该温度下的平衡常数K=__________；平衡状态B点时容器的容积_______VL。（填“大于”、“小于”或“等于”）

B．若A、C两点都表示达到的平衡状态，则自反应开始到达平衡状态所需的时间_______（填“>”、“<”或“=”）

C．在不改变反应物用量的情况下，为提高CO的转化率可采取的措施是________（写出一种即可）。

James's New Bicycle James shook his money box again.Nothing!He carefully 1 the coins that lay on the bed.$24.52 was all that he had.The bicycle he wanted was at least $90! 2 on earth was he going to get the 3 of the money?

That was the 10 of James's odd job(零工) business.For three months he worked every day after finishing his homework.He was amazed by the 11 of jobs that people found for him to do.He took dogs and babies for walks,cleared out cupboards,and mended books.He lost count of the 12 of cars he washed and windows he cleaned,but the 13 increased and he knew that he would soon have 14 for the bicycle he longed for. The day 15 came when James counted his money and found $94.32.He 16 no time and went down to the shop to pick up the bicycle he wanted.He rode 17 home,looking forward to showing his new bicycle to his friends.It had been hard 18 for the money,but James knew that he valued his bicycle far more 19 he had bought it with his own money.He had 20 what he thought was impossible,and that was worth even more than the bicycle.
