上一次的ch.5化學習題翻譯是x1874負責的.. 他說因為是應太多人的回應才做 不過po上去的時候 我本人已經把習題85%完成 其餘的都是不懂計算的題目... 所以對於我來說,有沒有翻譯已經不重要了~~ 有鑑於此,為了不再在交作業之前才看到有po這些重要的東西 所以我立刻把題目給翻譯過來 好讓同學不用看英文看到吐血XDDDD 現在 廢話少說 立刻看看ba!!!! ps.若果有翻譯不當,錯漏百出,或者是任何人為疏忽,小弟甘受指教!! 還有離子的電荷可能我打得不太清楚....如果真的看不懂,那我先orz... (我看到上次的ch.5的習題翻譯,心想'x1874早一點po出來,我就不用看英文看到吐血了... 還差點爆肝XDDD.不過還是感謝x1874給我一個賺p幣的好點子XD,謝謝!!) 淺藍色題號代表難題喔~~ <-->代表雙箭頭(可逆反應) ch.7 exercises ch.7 習題 79.

Is an aqueous solution of NaHSO4 acidic, basic, or neutral? What reaction occurs with water? Calculate the pH of a 0.10 M solution of NaHSO4.

Hemoglobin (abbreviated Hb) is a protein that is responsible for the transport of oxygen in the blood of mammals. Each hemoglobin molecule contains four iron atoms that are the binding sites for O2 molecules. The oxygen binding is pH-dependent.The relevant equilibrium reaction is as follows: (HbH4)4+(aq) + 4O2(g) <--> Hb(O2)4(aq) + 4H+(aq) Use Lw Chatelier's principle to answer the following. a. What form of hemoglobin, (HbH4)4+ or Hb(O2)4, is favored in the lungs? What form is favored in the cells? b. When a person hyperventilates, the concentration of CO2 in the blood is decreased. How does this result affect the oxygen-binding equilibrium? How does breathing into a paper bag help to counteract this effect? c. When a person has suffered a cardiac arrest, injection of a sodium bicarbonate solution is given. Why is this injection necessary? 94.血紅素(簡稱Hb)是一種在哺乳動物的血液中負責運送氧氣的蛋白質.每個血紅素分子包 含4個有著黏結氧分子的地方的鐵原子.pH值取決於黏結了多少氧分子. 有關平衡反應式如下: (HbH4)4+(aq) + 4O2(g) <--> Hb(O2)4(aq) + 4H+(aq) 用Lw Chatelier原理回答以下問題: a. (HbH4)4+ 及 Hb(O2)4 形式的血紅素,哪一種有利存在於肺部?哪一種有利存在於細胞 之中? b. 當一個人用力呼吸的時候,在血液中的CO2濃度會減少.這種結果如何影響氧分子黏結的 平衡?在紙袋中呼吸如何抵消這種影響? c. 當一個人心臟停跳時,必須採取注射重碳酸鈉溶液的急救方法.為什麼要採取這樣的注 射方法? 98. Acrylic acid (CH2 = CHCO2H) is a precursor for many important plastics. Ka for acrylic acid is 5.6 x 10^-5. a. Calculate the pH of a 0.10 M solution of acrylic acid. b.
