Experiment 7 Experiment 7 The partition of Organic acid between Water and Organic solvent Objectives Understand the partition of a solute between two immiscible solvents. Introduction A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., pipets, burets, volumetric flasks) is called a volumetric analysis. For a volumetric analysis procedure, a known quantity or a carefully measured amount of one substance reacts with a to-be-determined amount of another substance with the reaction occurring in aqueous solution. The volumes of all solutions are carefully measured with volumetric glassware. The known amount of the substance for an analysis is generally measured and available in two ways: 1. As a primary standard: An accurate mass (and thus, moles) of a solid substance is measured on a balance, dissolved in water, and then reacted with the substance being analyzed. 2. As a standard solution: A measured number of moles of substance is present in a measured volume of solution - a solution of known concentration, generally expressed as the molar concentration (or molarity) of the substance. A measured volume of the standard solution then reacts with the substance being analyzed. The reaction of the known substance with the substance to be analyzed, occurring in aqueous solution, is generally conducted by a titration procedure. The titration procedure required a buret to dispense a liquid, called the titrant, into a flask containing the analyte. A reaction is complete when stoichiometric amounts of the reacting substances are combined. In a titration this is the stoichiometric point. In this experiment the stoichiometric point for the acid-base titration is detected using a phenolphthalein indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the endpoint of the indicator. Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of the indicator.

請問第49題,為什麼F選項也可以選啊?我覺得Linda是可以接受,只是說希望價格降低。 應該是要價格降低才會買的情況,這題才能選F吧?

第貳部分、混合題(占10分) 說明:本部分共有1題組,每一題配分標題末。限在答題卷標示題號的作答區內作答, 並以規定用筆作答。 Even if you're not a vegetarian, there's a good chance you've heard of plant-based meat. These meat substitutes are often advertised as beneficial for the environment. But do the customers really like them? Read the following chatroom discussions about GreenBurger, a product using alternative-meat patties. (A) Olivia That's a firm NO! I tried one when I was a prep cook for Next Level Burgers...tasted awful, just like mashed peas gone to rot. (B) Smith I haven't tried them. I just don't see the point. They are heavily processed with more calories and sodium than meat and are more expensive too! Unless you are a strict vegetarian and eschew meat for ethical reasons, meat is surely a better deal. (C) Mika Not really. It tastes too much like actual meat. If I wanted to eat a dead cow, I would go for real burgers. Being vegan means I try to stick to plant food. But this is just not something that will ever interest me. (D) Thomas GreenBurger just tastes "beany" to me, so I think that whatever form it comes in, it works better in recipes that would usually contain beans, such as in a rice bowl (as ground meat substitute). That being said, I'm definitely a carnivore and prefer meat, but I don't see anything wrong with choosing one of the fakey- fakey meaty things once in a while-just for a change. (E) Rico I finally tried one last week. It didn't taste that bad, but I was surprised to find it had 40 more calories than the meat version! Isn't it supposed to be a healthy choice? (F) Linda I liked it fine. I did NOT like the price, though. Hopefully that will come down. I'm trying to eat less beef. (G) Ablo Yes! My whole family does. We've been mostly vegan 90% of the time for the last 6 years and we cannot thank GreenBurger enough! Especially when a burger craving hits...a GreenBurger does the trick. I've tried all kinds of vegan "burgers," and GreenBurgers are closer to what I'm looking for. In fact, I can have them every day-vegan or not! (H) Alexander Well, they taste good if you add plenty of spices and sauces. Good for you? No, not at all. They're highly processed and contain no vegetables. They also contain a very large amount of processed coconut oil, which is even worse than lard. It's a killer for sure if eaten regularly. So why risk your life? -9- 112年學測 請記得在答題卷簽名欄位以正楷簽全名 英文考科 第10頁 共11頁 47-48 請從文章中找出最適當的單詞(word)填入下列句子空格中,並視語法需要做適當的字形變 化。每格限填一個單詞(word)。(填充,4分) On the whole, the chatroom discussions about GreenBurger mainly focus on the issues of price, and 48 concerns. 47 49.

己為什麼不行選(第10題)

下圖為國際地震中心(ISC)統計了 1904~2016年全球發生的3萬多個地震規模5.0以上的地 震資料,繪製成下圖,其中星星愈大代表規模愈大,顏色偏藍代表震源深度愈深。其中甲在太平洋 上,乙在南美洲西岸,丙在大西洋中間,丁在非洲東部,戊在中國西南部,己在日本南方海域。 2020年10月美國阿拉斯加的南部海域,在當地時間19日中午12時54分(臺灣時間 20 日清 晨4時54分)發生規模7.6的強震。據美國地質調查局(USGS)資料顯示,這起地震震央位在阿 拉斯加沙點市(Sand Point)東南外海91公里處,震源深度28.4公里,因太平洋板塊以每年6.4公 分的速度向西北方向俯衝,而造成太平洋板塊和北美板塊交界的逆斷層事件,引發這次的地震。請 回答以下問題: [生活時事 。 ☆ ☆ *甲 地震規模 5.5 6.0 6.5 7.0 7.5 8.0 8.5 9.0 9.5 0 20 50 BC 100 200 400 地震深度 700 9. 下列相關的敘述,哪些正確?(應選2項) 【圖表判讀 (A)甲位於錯動性板塊邊界(B)乙與位於相同類型的板塊邊界(C)丙與丁的岩漿活動都 是以玄武岩漿為主(D)丙的地震次數較少,是因為丙處多為深源地震(E)戊位於陸地 上,應不是板塊邊界。 10.甲~己的6個地點中,哪一個地點的狀況最接近右圖? 圈: 112020年10月的阿拉斯加地震應是那種類型的板塊運動造成的? 我爱聚合 12 承上題,此次地震是否有機會伴隨海嘯的發生?如果你是政府當 海溝、 火山 海洋地殼 大陸地殼 →岩石圈 - 軟流圈
