化学基礎のイオン化傾向の問題です 線を引いてる文についての質問なのですが、 化学反応式とは、酸化還元反応の化学反応式の書き方で作られていますか

① Cu AI Ag (Cul /cu AI HCI水溶液 HCl水溶液 |濃HNO3 水溶液 CuSO 水溶液 |AgNO3水溶液 濃HNO3 水溶液 (1) 気体が発生したものの図番号と, 発生した気体の化学式を答えよ。 (2) 金属が析出したものの図番号と,析出した金属の名称を答えよ。 (3) 金属が溶けたものの図番号と、溶け出した金属イオンの化学式を答えよ。 (4) 変化がない,あるいは変化が途中で進まなくなるものの図番号と理由を答えよ。 解答 (1) ① H2 ③ NO2 (2) ⑤ 銀 (3) ① A3+ ③ Cu2+ Cu2+ (4)② 水溶液中のH+ より 金属 Cuのイオン化傾向が小さいから。 ④ 水溶液中の Cu2+ より 金属 Agのイオン化傾向が小さいから。 ⑥ AI は濃HNO3 中では不動態となり溶けないから。 ベストフィット イオン化傾向 イオン化傾向が大きいほど酸化されて陽イオンになりやすい。 Li >K>Ca > Na > Mg > AI> Zn> Fe > Ni > Sn> Pb > (H2) > Cu> Hg > Ag > Pt > Au 解説 イオン化傾向の大きい金属が溶液中でイオンであるならば, 安定なので変化が起こらない。 逆に,イオン化傾 向の小さい金属が溶液中でイオンであるならば、不安定なため還元されて金属に戻ろうとする。 ① 溶液には,塩酸から生じる H+ と単体 AI が存在している。 イオン化傾向は AI>H の関係にあるので,AI は酸化されて AI3+ になる。 ② 溶液には,塩酸から生じる H+ と単体 Cu が存在している。 イオン化傾向はH> Cuの関係にあるので, 変化は起こらない。 ③ 濃硝酸は酸化力が強く Cuは酸化されて Cu²+になる。 ④ 溶液には, CuSO4 水溶液から生じる Cu2+と単体 Agが存在している。 イオン化傾向はCu>Agの関係 にあるので,変化は起こらない。 ⑤ 溶液には,硝酸銀水溶液から生じる Ag+ と単体 Cu が存在している。 イオン化傾向は Cu>Agの関係に あるので, Ag+は還元されて Agになる。 ⑥ Fe, Ni, Al は濃HNO3 中では不動態となり,それ以上変化は起こらない。 ⑤は変化が起こりそれぞれの化学反応式は次のようになる。 ① 2AI +6HCI→ > 2AICl3 +3H2 ③ Cu + 4HNO3 ← →Cu(NO3)2 +2H2O +2NO2 ⑤ 2Ag+ + Cu→2Ag+Cu2+ 水素が発生 二酸化窒素が発生 銀が析出 112 第3章 物質の変化

There are other ways, too. Some of them choose to join short-term work programs at companies called internships. These have some good points. Students will be able to know more about companies they are interested in, such as what kind of jobs there are and what kind of people are working there. Also, internships allow students to get to know other students. These students can encourage each other both during and after the internship. On the other hand, if students choose to join very short internships, they may not be able to understand the job they are doing before the internships end. Also, students who take part in internships may find it difficult to do well in their studies.
