2F：→ faraday825:W應該指的是"可能形成的狀態數目" 所以我選b 06/30 15:11
3F：→ shadowlin:謝謝你!!我懂了 06/30 16:19
4F：推 ghyujm:3.a 23.d 31.c 06/30 22:06

6F：推 faraday825:樓上 可以請教你23題的觀念嗎 因為我不會 謝謝XD 06/30 22:53
7F：→ shadowlin:鹽類陰離子如果是弱酸根, 酸性環境下會被質子化, 07/01 06:55
8F：→ shadowlin:造成該鹽類解離平衡移動,把陰陽子分開,分別判對酸鹼 07/01 06:58
9F：→ shadowlin:(A)酸/鹼 (B)酸/鹼(C)酸/鹼(D)酸/中 07/01 07:09
