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?

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.

想問那兩張表什麼意思😓 為什麼陽離子來自強鹼?

(2) 陽離子水解:M(aq) + HO(1) = MOH(aq) + H'(aq) A+(aq)+3H2O(l)=Al(OH)(S)+3H+(aq) Ka 說明: [H+] K [AI] K ①陽離子(A+)進行水解作用造成[H+]濃度上升,故為酸性陽離子。 ②若MOH 為強鹼(K,為極大值),則為弱酸(K,為極小值),則可視為不發生水解, 【M+為中性陽離子,例如:Na+、K+ 2.常見離子的酸鹼性 + 。 酸鹼性 陰離子 陽離子 酸性 NH4 Be²+ HC₂O4 HSO4 、HSO3 、Cu²+ Al³ 、Fe H,PO」 H₂PO3 Na 中性 、K、Rb、Cst 、Ca Sr Ba² 強鹼 鹼性 CIO、IT、Br、CT、NO、SO² CH,COO、CN、F、CO SO- HCOOC,OHCO, 不起 水解(強) NO₂ 二、正鹽的酸鹼性 正種類 溶液中的離子特性及實例 酸鹼性 強酸+強鹼 陽離子(來自強鹼)不水解,陰離子(來自強酸)不水解 KNO3、NaCl 中性 強酸+弱鹼 陽離子(來自弱鹼)會水解,陰離子(來自強酸)不水解 例 NH.C1、ZnCl、CuSO4 陽水解 [NHg*(aq) + H,O(1) =NH;(aq) + HO*(aq) Zn toH [Cl¯(aq) + H,O(1) *(不水解) 酸性 CI+H 強鹼+弱酸 陽離子(來自強鹼不水解,陰離子(來自弱酸)會水解 CH,COONa、KF、K-CO →Zn(OH)→ HCl 強 除水解 Na+(aq) + H2O(l)*(不水解) 鹼性 弱鹼+弱酸 [CH,COO¯(aq) + H2O(l)=CH,COOH(aq) +OH (aq) 陽離子(來自弱鹼)會水解,陰離子(來自弱酸)會水解, 故陰、陽離子在水中的水解強度決定水溶液的酸鹼性 15 NHF NHg+(aq) + H2O(l)=NH3(aq) + HO(aq) K=5.6×10-10 F¯(aq) + H2O(l) HF(aq) + OH (aq) K=1.4×10-1 ∵K』 > K∴ NHF(aq)為酸性。 (1)若陽離子的K>陰離子的K⇒呈酸性,如:NHF。 (2) 若陽離子的K=陰離子的K。⇒呈中性,如:CH,COONH』。 (3)若陽離子的K。<陰離子的K⇒呈鹼性,如:NH.CN。 Kaxkb =Kw 以K 與K的 大小而定
