油脂Aは1分子に平均何個のC=C結合を持つかという 問題なんですけどわかる方教えていただけると助かります！答えは5.55個です

(1) 油脂は, 高級脂肪酸3分子にグリセリン1分子が [ 1 ] 結合した化合物である。 油脂を水酸 化ナトリウム中で加熱すると, けん化されてグリセリンと脂肪酸のナトリウム塩, すなわち [ 2 ] を生じる。 油脂1gをけん化するのに必要な水酸化カリウムの質量 (単位: mg) の数値を,油脂 のけん化価という。 天然の油脂を構成する脂肪酸にはパルミチン酸やステアリン酸などのような飽和脂肪酸と, オレ イン酸、リノール酸、リノレン酸などのような不飽和脂肪酸とがある。 不飽和脂肪酸のC=C結 合には, アルケンと同様に臭素やヨウ素などの[ 3] 分子が容易に付加するが, 特に, 油脂 100g に付加するヨウ素の質量(単位:g) の数値を、油脂のヨウ素価という。 また, ニッケルを触媒と (2)] して水素を付加すると融点が高くなる。 このようにしてできた油脂を [ 4 ] といい。 マーガリ ンなどの原料となる。 ある油脂Aの脂肪酸組成を分析したところ, オレイン酸 (C17H 33 COOH) 25%, リノール酸 (C17H31COOH) 65%, リノレン酸 (C17H29 COOH) 10%であった。

年度 英語 15 [II] Write (VI) opinions. Write your answer in about 100 English words, not counting punctuation marks. Mr. John Spence's opinion on e-bikes My electric bike is one year old on Thursday, and it was a 75th birthday present. I have only ever been a casual cyclist, but had given my old bike away, as my creaky knees combined with living at the top of a hill-meant that I rarely used it. But with my e-bike I feel so empowered. It is so easy to get around to do a few errands that it often seems quicker than using a car and having to find parking. If anyone is tempted by the idea, I strongly recommend giving it a try. Ms. Liz Ormond's opinion on e-bikes Mr. Spence's enthusiastic praise for e-bikes omits any reference to pedestrians. There is no mention that they are more dangerous than other bikes. Can he tell us what 19 OC DE BESLOT ACAI BESI TE OF 0.8. safety studies have been done in relation to pedestrians, particularly in shared space, and what discussions have been held with organisations such as the Royal National Institute of Blind People? Also, since the motors are effective enough to propel bikes loaded with shopping and children, what effect would the additional weight have in a collision with a pedestrian?

問題 3 以下の英文を読んで、次の問いに答えなさい。 (*のついた語には語注が ある。) If you are able to step outside and hear many types of birds, you might also have a greater feeling of well-being. Two studies show that hearing diverse birdsongs may help increase our happiness. (A) One study was done by researchers at California Polytechnic State University. A research team studied the effects of birdsong ( 1 ) people walking through a park in the U.S. state of Colorado. A biology graduate student, Danielle Ferraro, led the study. "There could be an evolutionary reason why we like birdsong so much. And the idea is that when we hear birdsong it could signal safety to us," Ferraro says. There could be many other reasons, too. Ferraro states that in some areas around the world birdsong can also signal the arrival of spring and nice weather. Bird diversity, she adds, can also mean a healthy environment. She explained her study to Voice of America (VOA). Ferraro and her team played recorded songs from a diverse group of birds native to the area. They did this on hiking trails in a park in Boulder, Colorado. (2) several weeks, the researchers played recorded birdsong at certain times of the day and other times they did not. Then they talked with hikers after they ( 3 ). Hikers who heard the recorded diverse birdsongs reported a greater sense of well-being than the people who heard simply the natural birds. The researchers suggest that both the bird sounds and biodiversity* can increase feelings of well-being. Ferraro explained that she used native birdsong for the study. This way it would sound as natural as possible. They also did the study during the summer. She explains why this is important. "So the study ( 4 ) in the summer and that's kind of important because the spring is most birds' breeding* season. And if we play the birdsong during breeding season, that might have disturbed them. (B) We didn't want to disturb the birds too much." The study was published in an academic journal called the Royal Society B in December 2020. - 10- ◇M2 (310-15)
