請問這題為什麼不是選D呢 啞鈴型的話不是兩個電子應該在同一個p軌域上嗎

啞鈴 9. Which of the following indicate two electrons in the dumbbell shaped orbital which n=4? & (A)4s² 1(B) 4p² L 4p² 1 1 (D) 4p² 1

陰離子的電子親和力不是跟游離能差一個負號嗎？為何不能選C

16.The electron affinity of fluorine is essentially equal to the negative of the ionization energy F. the ionization energy F. the negative of the ionization energy F™. the ionization energy Ne. the negative of the ionization energy Ne. B A) B) C) D) E)

我看不懂這個是怎麼運作的😭😭😭 請問有人可以解釋一下原理嗎？

熱電偶是將兩種不同材料的導體或 半導體焊接起來,熱電模組 (Thermoelectric generator module: TGM)是由熱電偶所組合成的熱電偶 堆,當兩側存在溫差時,便會產生 電動勢在迴路中形成電流。圖一為 熱電偶的操作圖,由半導體的P型與 N型材料所焊接而成,當接觸冷熱端 面時即會產生正負壓差。圖二為塊 材式(Bulk)熱電模組以及薄膜式(Thin- film)熱電模組實體照,薄膜式熱電 模組可以在相同的單位面積下製作 更多的熱電偶,擁有更好的發電及 散熱效率。 P型材料 G 負極 圖一:圖一、 熱電偶操作圖 熱端 冷端 正極 N型材料

哪位帥哥能拔刀相助一下，解釋一下為何

2-41 The 0-H hydrogen in acetic acid is more acidic than any of the C-H hydrogens. Explain this result using resonance structures. o H Acetic acid H H :0: :0: O=0 :: H-C =0 H-C H-C C=0 c H H H H H H The O-H hydrogen of acetic acid is more acidic than the C-H hydrogens. The-OH oxygen is electronegative, and, consequently, the-0-H bond is more strongly polarized than the -C-H bonds. In addition, the acetate anion is stabilized by resonance,

誰能解釋一下為什麼？下面英文解答看不懂

2-41 The 0-H hydrogen in acetic acid is more acidic than any of the C-H hydrogens. Explain this result using resonance structures. O=U H -H Acetic acid \" HH :0: :0: II C H-c H-C H- C=0 H H H H H H The O-H hydrogen of acetic acid is more acidic than the C-H hydrogens. The-OH oxygen is electronegative, and, consequently, the-O-H bond is more strongly polarized than the -C-H bonds. In addition, the acetate anion is stabilized by resonance.

求詳解謝謝各位🙏
