难溶性杂卤石(K₂SO₄·MgSO₄·2CaSO₄·2H₂O)属于“呆矿”，在水中存在如下平衡：

K₂SO₄·MgSO₄·2CaSO₄·2H₂O(s) 2Ca^2＋＋2K^＋＋Mg^2＋＋4＋2H₂O

为能充分利用钾资源，用饱和Ca(OH)₂溶液溶浸杂卤石制备硫酸钾，工艺流程如下：

(1)滤渣主要成分有________和________以及未溶杂卤石。

(2)用化学平衡移动原理解释Ca(OH)₂溶液能溶解杂卤石浸出K^＋的原因：_________________________________________________。

(3)“除杂”环节中，先加入________溶液，经搅拌等操作后，过滤，再加入________溶液调滤液pH至中性。

(4)不同温度下，K^＋的浸出浓度与溶浸时间的关系如图。由图可得，随着温度升高，

①________________________________________________________，

②________________________________________________________。

(5)有人以可溶性碳酸盐为溶浸剂，则溶浸过程中会发生：CaSO₄(s)＋CaCO₃(s)＋

已知298 K时，K_sp(CaCO₃)＝2.80×10^－9，

K_sp(CaSO₄)＝4.90×10^－5，求此温度下该反应的平衡常数K(计算结果保留三位有效数字)。

“Long time no see” is a very interesting sentence. When I first read this sentence from an American friend’s email, I laughed. I thought it was a perfect 21       of Chinglish. Obviously, it is a word-by-word literal(照字面意思的) translation of the Chinese greeting with a ruined English grammar and structure! Later on, my friend told me that it is a standard American 22         . I was too amazed to believe her. Her words could not convince me 23          . So I did a search on www.google.com. To my surprise, there are over 60 thousand web pages 24        “long time no see”. This sentence has been 25          used in emails, letters, newspapers, movies, books, or any other possible place. Though it is sort of informal, it is part of the language that Americans use daily.  26         , if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.

　　Nobody knows the 27         of this Chinglish sentence. Some people believe that it came from Charlie Chan’s movies. In the 1930s, Hollywood moviemakers successfully 28         a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan liked to teach Americans some Chinese wisdom by quoting(引用) Confucius(孔子). “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world thanks to the popularity of these movies.
