想問這題，謝謝🙏

探究與實作:離子液體的選用 近年來,一種可再回收使用的綠色溶劑:離子液體,由於其具有低蒸氣壓、低熔點、 高極性、不可燃、耐強酸、高熱穩定性、高導電度、電化學性佳及較廣的液體溫度範圍等 特殊性質,在化學上的應用非常廣泛。此外它還是一種可依所需性質來組合不同陽離子、 陰離子的溶劑,因此離子液體溶劑也被認為是設計者溶劑(Designer Solvent)。 常溫離子液體(room-temperature ionic liquid, RTIL)是指在 常溫時以液體呈現的離子化合物。然而,我們日常接觸到的無機 鹽類,常溫下幾乎都是固體。以食鹽(氯化鈉)為例,若要作為 溶劑,至少需加熱到 801°C 以上才能使用。這是因為無機鹽的正 負離子在晶格中排列緊密,且彼此吸引力強,導致熔點極高,如 圖一所示。 負離子 正離子 圖一 無機鹽晶體結構 負離子 - 幸好聰明的科學家發現,若能使正負的堆積鬆散,可有效降低 其熔點。科學家設計出一種特殊的晶體,如圖二所示,此晶體是由 一有機物正離子及一個帶有非定域(delocalized)舖 電荷的負離子 團所組成。通常正離子是含氮的有機物如胺類、氨基化學物等,它 們的體積較金屬離子大,構造也往往無對稱性,而非定域電荷的負離子則和一般無機鹽類相 似。由於這樣的特殊晶體,晶格的引力較無機鹽弱,也就是其晶格構造不如無機鹽緊密,使 得其熔點下降,而達到常溫離子液體(RTIL)的目標。請回答 8.~10.題: 非定域(delocalized),指電子並不侷限於分子內某化學鍵上,而能在鄰近的數個化學鍵 上遊走。 共振 (改編自《科學月刊第555 期》第214頁〈液態的鹽 —— 常溫離子液體〉) 正離子 圖二 RTIL 晶體構造

All of the _1_ live in the same apartment building. Both groups of residents must sign a contract agreeing to spend two or more hours a week with someone from the other generation.

All of the tenants have their own apartment, but they can also use shared areas of the building, which are designed to encourage social interaction.

17題的C、D選項的差別是什麼，為什麼不能選C?

The five-pointed star drawn with five lines is known today as the pentagram. It is an ancient symbol which has held different meanings. Today, we can see the pentagram 16. as jewelry or designs on clothing. The Sumerians were the first to use the five-pointed star polygon. They wrote about the symbol in records 17. 3000 B.C. In the context of that civilization, the pentagram was a character in a writing 18. system. The Babylonians, a culture with close historical links to Sumer, used the pentagram the planets. Its five points indicated five planets Mercury, Venus, Mars, Jupiter, and Saturn. In ancient China, the pentagram corresponded to Wu Xing, the five elements that make up the world: metal, wood, fire, earth, and water. In European folklore, it was said to come with magical properties. The 19. of the star affected its significance. With one point facing upward, the pentagram represented "white” magic (good). 20. with two points facing upward, the same symbol stood for "black" magic Fz2t62 (evil). Nowadays the symbolism of the pentagram is still commonly used, but it is good to know more of its history than just a fashion statement. BT 16.
