最新試題

29.、30. 題為題組
表 7 為「碘鐘實驗」所需的試劑濃度和取量的實驗紀錄表，且已知過硫酸根 (或稱過氧二硫酸根，S₂O₈²⁻) 與碘離子 (I⁻) 反應形成硫酸根 (SO₄²⁻) 和碘分子 (I₂)，硫代硫酸根 (S₂O₃²⁻) 會與碘分子 (I₂) 反應形成四硫磺酸根 (S₄O₆²⁻) 和碘離子 (I⁻)，然而碘分子會與澱粉產生藍黑色溶液。實驗步驟如下：
(1) 先將甲、乙、丙及丁混合在一起。
(2) 添加戊溶液後，迅速加入己溶液並開始計時。
(3) 溶液會先呈無色狀態，而後隨反應的進行，轉變成藍黑色。由加入戊溶液混合後到變色的這段時間可精確計時，變色時間長短則受反應物濃度之影響。
試回答下列問題：

【題組】30. 若已知「碘鐘實驗」之速率定律為 r = k[S₂O₈²⁻]ᵐ[I⁻]ⁿ，依表 7 數據求出 m + n 為多少？並預測實驗編號 4 變色時間 t 為多少秒？(2 分)
【題組】
29. 進行「碘鐘實驗」所需的實驗器材有圖 8 所列 (A)、(B) 兩種，試說明器材名稱與用途為何？(4 分)
27.、28. 題為題組
若 A、B 溶質於水中的溶解度與溫度之關係直線如圖 7 所示，今將 A 和 B 之混合物 15.0 克與 100.0 克水混合加熱至 100℃ 時，得 G 溶液，再過濾 G 溶液，此時發現有 2.0 克 B 未溶解。回答下列問題：

【題組】28. 先將 G 溶液中的未溶解 2.0 克 B 移除後，再使溶液溫度下降至 50℃，則沉澱物中 B 的重量百分率為多少 %？(取至小數後 1 位) (2 分)
四、閱讀測驗【請依照段落上下文意，選出最適當的答案】 Forty-two years ago, hospital workers took Maria Gonzalez’ son from her arms right after birth. Documents say they later told her he had died. Now, she was meeting him face-to-face at her home in Valdivia, Chile. His effort to find the birth family he never knew began in April. That was when he read news stories about adoptees who had been born in Chile and had been reunited with their birth relatives through a Chilean nonprofit group called Nos Buscamos. The organization found that Thyden had been born prematurely at a hospital in Santiago, Chile’s capital, and had been placed in an incubator. Gonzalez was told to leave the hospital, but when she returned to get her baby, she was told he had died and his body had been removed, documents say. “The paperwork I have for my adoption tells me I have no living relatives. And I learned in the last few months that I have a mama and I have four brothers and a sister,” Thyden said. He now lives in Ashburn, Virginia, where he works as a criminal defense lawyer. The group Nos Buscamos estimates that tens of thousands of babies were taken from Chilean families in the 1970s and 1980s. That claim is based on a report from the Investigations Police of Chile, a civilian group, which examined the passports of Chilean children who left the country and never returned. “The real story was these kids were stolen from poor families, poor women, that didn’t know how to defend themselves,” said Constanza del Rio, founder and director and Nos Buscamos. Over the past nine years, Nos Buscamos has organized reunions for more than 450 adoptees and their birth families, del Rio said. Other nonprofit groups are doing similar work, both in Chile and the U.S. Thyden said his reunion with his birth family was a success. But, he knows that reunification might not go as well for other adoptees.
【題組】50. What is most likely the meaning of “adoptee”? (A) A person who is taken into another family and cared for as the family’s own child. (B) A person who takes other people away illegally and by force to demand some money from their family. (C) A medical doctor who performs surgery to repair parts of the body by the transfer of tissue. (D) A person who is employed to take care of a large building, such as a school.
【題組】49. What is the goal of Nos Buscamos? (A) To help reunify families. (B) To offer free medical treatment for poor children. (C) To provide free education for poor children. (D) To make some housing more affordable.
【題組】48. Why did Thyden’s mom leave the hospital without him in the first place? (A) He was very weak. (B) He was taken away by his father. (C) She needed to apply for a passport. (D) She had no money for the hospital.
