之前在衝期末考，考古題進度有些落後 PART II還在奮鬥中所以先來問PART I的=w= --------------以上廢話----------------- 對答案+問問題 1~5 CC(C)EA 6~10 DDCD(B) 11~15 ?BCD(D) 16 A ?是不會的 ()是答案不確定的 --------------問題開始----------------- 3.Which one of the following statements is "correct" about the atomic mass unit (amu)? A.One 12C(←碳12) atom has amass of 12.0000 amu. B.1 amu is defined as one-twelfth the mass of one 12C atom which has an atomic mass of 12 amu. C.The atpmic mass of 35Cl(←氯35) atom is 35.453 amu. D.The mass of 12.011 amu for the carbon element shown in the periodic table is a real mass of one 12C atom. E.The atomic mass of 1H atom is a relative mass to the atomic mass of 16O(←氧16). 這題我選C 但選項B不確定如果B是錯的，請說明原因 **此題元素符號前的數字表質量數而非係數** ------------------------------------------- 10.Consider the reaction of 2 CO(g) + O2(g) → 2 CO2(g) with △H=-566.0 kJ at 25 ℃. Which one of the following statements is "correct" if 2 moles of CO react with air completely? (R=8.314J/K‧mol) A.The work done by the surrounding is 2.48 kJ. B.The reaction system does work to the surroundings. C.The reaction is endothermic. D.△E=-568.5 kJ. E.△H=△E. 這題我選B 請問選項A要如何計算? (基本上除了C是錯的外，其它選項都是...不知道) ------------------------------------------- 11.A wave function of atomic orbitals in the hydrogen atom is 1 -r/2 Ψ=---------re cosθ 4√(2π) Which is the most likely symbol for the atomic orbital? A.1s B.2s C.2p D.3s E.3d 這題公式看不懂(也沒看過) 不會寫... ------------------------------------------- 15.Which oneof the following statements iabout the ionization (IE) and electron affinity (EA) is "true" ? A.IE1(←第一游離能): O＞N B.EA of He＞0 C.EA: N＞O D.IE1:Ne＞F E.IE1 of H=1312 kJ/mol and IE2 of He=2624kJ/mol. 這題我選D 但選項B&C中，當軌域為半滿(5A)或全滿(8A)時，因不易吸收電子，所以 EA會＞0 還是＜0? ------------------------------------------ 嗯...大概先這樣 PART II 之後整理完也會PO上來(問題有點多) 煩請高手們幫忙解惑感激不盡~~ (此部份已寫完的戰友們歡迎來對答案喔XDD) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.130.96.155
