[化學] About boiling and freezing point? Pa …
1) which of the following molecule has the lowest boiling point?
(A) H2O (B) H2S (C) H2Se (D) H2Te
這題應該不是看原子量 也沒有HB 畫結構又很相近 ?????
2) which of the following solution (all 0.01M) has the lowest freezing point?
(A) NaCl (B) Na2SO4 (C)MgSO4
是找依數性質 嗎? (B)????
3) which of the following aqueous solution will have the highest freezing
point?
(A) 0.2m NaCl (B) 0.2m MgCl2 (C) 0.1m NH4NO3 (D) 0.1m Na3PO4
(C) 是0.1X2(依數性)??? 這樣解嗎?
感恩 感恩 謝謝解題的高手
