As any diplomat from Britain, Austria or Turkey can tell you, handling the legacy of a vanished, far-flung empire is a tricky business. But for Georgia, the gap between old glory and present vulnerability is especially wide.

Today’s Georgia is diminished by war, buffeted by geopolitics and recovering from post-Soviet chaos. But 800 years ago the country was a mighty military, cultural and ecclesiastical force. Its greatest monarch, Queen Tamara, defeated many foes (including her first husband) and built fine monuments. In her time, Georgia also had a big stake in the Christian life of the Holy Land. From Jerusalem to the Balkans, Georgia’s priests, artists and church-builders were active and respected. So too were its poets, like Shota Rustaveli, the national bard who dedicated an epic to his beloved queen.

In between seeking western aid and coping with power cuts, modern Georgia has pledged to keep a wary eye on every place where churches, inscriptions and frescoes testify to its golden age. That includes Greece, Turkey, Bulgaria, Romania and above all, Israel. Last year, Georgians were enraged when a fresco of Rustaveli, in a Jerusalem church under the care of the Greek Orthodox Patriarchate, was defaced, then badly restored. This year, a better restoration was done, but Georgians now want a promise that in all future restoration their own experts can take part. They also want to stop the seepage of Georgian frescoes and icons, supposedly under the Patriarchate’s care, on to the art market. Several times, Georgia has had to use its meagre resources to buy back pieces of the national heritage. The hope is that things will improve with the recent election of a new Jerusalem Patriarch, after his predecessor was ousted under a cloud of scandal.

Georgia’s ties with Israel are good, thanks to a thriving Georgian-Jewish community with happy memories of its homeland. Georgia also gets along with Greece, amid a fug of sentimentality over legends about the Argonauts that link the two nations. But can these warm, fuzzy feelings translate into better protection for an ancient culture That will be a challenge for Geld Bezhuashvili, who succeeds Salome Zourabichvili, the French-born diplomat who was sacked, after a power struggle, as Georgian foreign minister on October 19th.

小强同学看到妈妈将买来的排水口洗净剂(主要成分:过碳酸钠、柠椒酸)洒在厨房排水口网状盖的底部,倒上温水后有气泡冒出。激发了探究欲望。他决定与学习小组的同学,对所产生气体的成分及排水口洗净剂主要成分的作用进行探究。  

[探究活动一]   老师提示:排水口洗净剂与水作用的生成物中有两种常见的气体。同学们根据所学的化学知识设计并进行如下图所示的实验。

实验中观察到如下现象:A中有气泡产生;B中的澄清石灰水变浑浊;C中收集到的气体能使燃着的木条燃烧更旺。

由此同学们得出结论:生成的两种气体分别是: _______________________ 。B中有关反应的化学方程式为 ____________________

[探究活动二]老师提供了一瓶过碳酸钠(Na2CO4),引导同学进行如下实验探究:

根据上述实验结果得出结论:无色溶液x中含有的一种溶质是____________ 。根据质量守恒定律,同学们对溶液x中还可能存在其它溶质作出如下猜想: ① Na2CO3 ②NaHCO3 ③Na2CO3和NaHCO3的混合物。

资料摘要I:氯化钙溶液呈中性;氯化钙溶液与碳酸氢钠溶液混合不发生反应;氯化钙溶液与碳酸钠溶液混合后发生如下反应:Na2CO3 + CaCl2== CaCO3↓+ 2NaCl

资料摘要Ⅱ; NaHCO3溶液呈碱性;碳酸氢钠、碳酸钠分别与足量的酸反应产物相同。

资料摘要Ⅲ:柠檬酸是一种有机酸,与盐酸具有相似的化学性质。

实验验证:综合上述两个探究活动的结果,同学们明确了上述猜想_________ (填序号)是正确的。请你简述在排水口洗净剂与水接触产生气体的过程中,柠檬酸所起的相关作用:_______________________________
