Question 46-50


Here is a letter from Colorado State University to inform the applicant Mr. Li that he has been admitted to Cognitive Psychology Program beginning with the fall semester of 2000.
Dear Mr. Li,
Thank you for your interest in graduate study at Colorado State University. You have been admitted to our Cognitive Psychology Program beginning with the fall semester of 2007.
The enclosed brochure provides a derailed description of the Cognitive Psychology Program, including, the program of study, degree requirements, mentorship program, faculty research interests and laboratory facilities.
We hope you will join us this fall. Your undergraduate record, interests and experience indicate that you will gain much new and exciting knowledge at CSU. Please notify me in writing of your decision to accept or reject this offer, prior to April 15. If you have any questions, feel free to contact me at 555-555-5555.
Sincerely,
Hugh Camera

实验题

据中广网2010年5月3日报道:中卫市孟家湾路段一辆汽车满载的浓硫酸发生严重泄漏。浓硫酸沿公路流淌,并向路基两边蔓延。消防官兵立即启动应急预案,用沙土封堵,控制浓硫酸进一步蔓延,同时设法封堵泄漏点,并对路面上的浓硫酸进行稀释和清除。看到这则新闻,学校的化学活动小组开展了一次关于浓硫酸腐蚀性及事故处理的研讨活动。请你也参与其中积极探究,并将活动记录补充完整。

(一)浓硫酸的腐蚀性实验探究

【实验用品】浓硫酸、小木条、玻璃片

实验步骤实验现象结论
浓硫酸有强烈的腐蚀性,使用时应十分小心
(二)对浓硫酸泄漏事故处理的讨论(1)小明同学认为,如果仅用水稀释,并不能消除事故所造成的污染。因为从溶液的角度看,在稀释过程中溶质的             没变,仅仅是             变小了。小敏同学受到启发,制订了如下方案:

采取措施依据原理效果评价反应类型
向硫酸所流经范围抛撒大量
氢氧化钠小颗粒硫酸与氢氧化钠反应将硫酸转化为无害物质,
可消除污染
【思维拓展】写出小敏所依据原理的化学方程式                          。小聪同学认为,小敏同学的方案虽然有效,但有一个缺陷:如果用量把握不准又可能引发新的污染,因为                              。 (2)请你参照小敏的设计方案,结合小聪的看法,也设计一个方案。

采取措施依据原理效果评价
将硫酸转化为无害物质,
可消除污染
