最後の酢酸は何故２モルから酢酸イオンを引くのでしょうか

4.120gの酢酸 (CHCOOH) が溶液1L中に溶けている。 1価の弱塩基 酢酸 (CH3COOH)、酢酸イオン(CH3COO')、 水素イオン(H*) は その水溶液 1L中にそれぞれ何mol 存在するか? Imod 60g №2 Xmol 120g 1000mL ただし、酢酸の分子量を60 電離度を0.016 とする。 酢酸 120g = 2 mol ->>> 120g÷分子量 60 酢酸イオン 水素イオン : 2 mol × 電離度 0.016 = 0.032mol 酢酸: 2mol-0.032mol = 1.968 mol 2mol 2×0.016=0.032mol 酢酸: 1.968 mol 酢酸イオン: 0.032 mol 水素イオン: 0.032mol H2SO4→504 +21 酸が持っているHの数 2価←酸の価数 NonH Na+OH 塩井が持てるOHの数

問4のクについての質問です。解答の1番下の赤い星の2行上に、この問題で重要となるv≒v3は、問題文で与えられるべきであると書いてあるのですが、vもv3もNO2の生成速度であるので、すぐわかることだと思っていたのですが、何か勘違いしていますでしょうか？？

(b) 二酸化窒素を生成する反応の一つに, 式(2)に記す一酸化窒素の酸化反応がある。 2 NO + O2 → 2NO2 (2) 化学反応の速度は温度上昇とともに増大するのが通常である。 しかし, それとは 逆に、気相における式(2)の反応では、ある温度範囲においては温度上昇とともに反 応速度が低下する。この反応速度』はNO2の生成速度であり,反応物の濃度を用 v=k[NO][02] (3) のように表されることが実験的にわかっている。 ここで,kは反応速度定数であ る。 以下では,上記の”の一見異常な温度依存性を説明する機構の一つについて考察 する。それは,式 (2) の反応が次の式 (4) と式 (5) に記した二段階の素反応によって進む 機構である。 NO + NO N2O2 N2O2 +02 ← k 2 NO 2 45 (5) 式(4)の正・逆反応におけるN2O2の生成速度と分解速度 12,および式(5)にお NO2の生成速度 v3 は, それぞれ V 01=k1 [NO]2,02=k2[N202],v3=k3 [N2O2] [02] (6) We U2 と表され, v2 は0よりも充分に大きいものとする。 すなわち, 式 (5) の反応に よってN2O2が消費されても, 式 (4) の平衡が速やかに達成されるものとする。 この とき式(4) の反応の平衡定数 Kおよび式 (2) の反応の速度定数kを,k, k2, ks を

stories as books. She sent her first book to various publishers, but none of them were interested in publishing it. Unlike the publishers, Potter felt certain that the book would be a success, so in 1901, she paid one publisher to print copies of The Tale of Peter Rabbit. Because of costs, this first version was in black and white. The book was quickly sold out, so the publisher decided to publish a color version. This became a bestseller, and the publisher made a lot of money from that book and the other 22 books written later. Potter's sense of business, though was shown in the way she created and sold goods related to the books. After publishing the first book, she made a doll of Peter Rabbit and patented* it. This was the first time a character from a book had been patented. She then went on to develop dolls, games, dishes, and other products. Today, we are used to seeing toys and products connected with characters from books for sale. Peter Rabbit, though, was the first of these. The methods Potter developed to make a successful business out of her children's books are the ones that are often used by entertainment businesses today.

Task 1 Read the ad below. Underline the qualities that Jenna is looking for in a roommate. NEED A RESPONSIBLE ROOMMATE I'm a 20-year old female history student at CUNY. I'm looking for a tidy and friendly roommate to share a two-bedroom apartment near the university. The apartment has furniture, Internet, and cable TV. We'll share a bathroom and a living room. The available bedroom is large. The rent is $300 a month. The perfect roommate would also be a student. I have a small dog, so you have to like dogs. I also can't take any other pets. If you are a smoker, you MUST smoke on the balcony. I get along well with creative and knowledgeable people. I'm pretty talkative and would be happy to live with a similar person. Please send me an e-mail (jennabusybee@cunyemail.edu) and tell me about yourself. I would like to hear about your studies, personality, and why you would make a good roommate. Jenna Task 2 (00 Write an e-mail to Jenna (80-120 words). Tell her about yourself.

ample practices varied across time and place. The truth is that we about what preliterate societies knew or believed. But they left behind *. evidence of their attention to the movements of the Sun and the phases of the Moon. And we can be sure that whatever questions they asked of the heavens were very different from those that motivate space exploration today. (A) rotic othe In reality, the difference between ancient and modern knowledge systems is more qualitative than quantitative; it is not about how much is known, but about what questions are important and about the acceptable ways of asking and answering those questions. And while we may not easily be able to slip between our modern worldview and those of others, we can nonetheless attempt to do so by asking not what ancient people knew about the world, but what their questions were when they looked at it. If we do this in the case of Mars, examining a few of the earliest known examples from around the world, we can see how sky knowledge was considered important to the functioning of the state whether it was *astrological knowledge in the service of good governance, or knowledge of bloodlines and relationships with the gods and other sky entities, which was used (B) - verdd
