UNIT 1 5 Reading Passage 10 15 20 20 25 Listening There are more than 37,000 known species of spiders in the world in a wide variety of shape's and sizes! The largest spiders in the world live in the rain forests of South America and are known by the people who live there as the "bird-eating spiders." These spiders can grow up to 28 centimeters in length- about the size of a dinner plate, and, as their name suggests, have been known to eat small birds. In comparison, the smallest species of spider in the world is native to Western Samoa. These tiny spiders are less than half a millimeter long — about the size of a period on this page and live in plants that grow on mountain rocks. - Some people like to keep spiders as pets, particularly tarantulas, which are native to North America and can live for up to twenty-five years, Most people, on the other hand, do not like touching spiders, and a significant number of people are afraid of them, mainly because of their poison. However, despite their bad reputation, only thirty of the 37,000 known species of spiders are deadly to humans. Spiders actually provide benefits to humans, by catching and eating harmful insects such as flies and mosquitoes. - - The main thing that makes spiders different from other animals is that they spin web's to catch the small insects they feed on. The unique silk of a spider's web is produced by special organs found spider web is five times in the lower part of the spider's body. It is light, elastic, and strong stronger than steel. Additionally, it is completely biodegradable. This means that the web will making it perfect for uses completely decompose¹ and eventually return to nature over time such as making fishing nets. Some people have tried to raise spiders commercially in order to collect the silk these spiders produce, but no one has ever really managed to make a go of it. One reason why these businesses never stand a chance is because it takes 670,000 spiders to produce half a kilogram of silk, and all of these spiders need living insects for their food. In addition, spiders are usually solitary² animals, and need to be kept alone. Researchers at an American company working together with two U.S. universities may have found a solution to making artificial spider web. Using genetically modified silkworms,³ the company hopes that in the long run it will be able to make large quantities of very light, very strong fiber for medical as well as other uses. Additionally, because the manufacture of the artificial web is from living silkworms, the industry potentially would be non-polluting and less harmful to the environment

(1)k=(H➕)2の2ってH2S→←2H➕➕S2-の2H➕の2を後ろに持ってきて(H➕)2となるのですか? (2)ともに0.10mol/Lの次の文です。なんで沈殿しないと分かるのですか? 教えてください。お願いします。

入試攻略 への 必須問題】 Fe²+ と Cd²+ をそれぞれ 0.10 mol/L ずつ含む混合水溶液に、25℃, pH=1.0 の塩酸酸性条件下で硫化水素を通じて飽和させると,CdS のみ が沈殿する。 CdS のみが沈殿する理由を説明せよ。 なお, 25℃における FeS と CdSの溶解度積は,以下の値を用いよ。 Ksp = [Fe2+][S2-] = 6.3×10-18 [mol/L2] Ksp [Cd²+][S2-] = 5.0×10-28 [mol/L2] また, 25℃における硫化水素の飽和水溶液の濃度は0.10mol/L で一定 であり、次の電離平衡が成立しているものとする。 りかからこっちに H2S H+ + S2 K = 1.2×10-21 [mol2/L2] ↓なんでこうなるので 【解説 答え - ここでKは電離定数である。 [H+] は, pH=1.0 なので, [H+] = 10-1 [mol/L] です。 [H2S] = 0.1 [mol/L] として よいので, [H+][s²-] [H2S] ų K= から [S2-] が求まります。 金属イオン濃度を [M²+] とすると, [M²+] [S²-] の値が Ksp より大きい場合のみ, 沈殿が生じます。 (10-')2.[S²]=1.2×10-21 0.10 H2S- pH=1.00 -FIST #13 。 [H2S] = 0.10[mol/L] 25°C (長崎大) v=[^gA]] [H+]^[S²]=1.2×10~21 K= [H2S] である。 [HS]=0.10 [mol/L], pH=1.0 なので [H+]=10-'[mol/L]を ①式に代入すると ↓なんで沈殿しない くわかるのか よって, [S²]=1.2×10-²0 [mol/L] [Fe°*] と[Cdf**] はともに 0.10mol/L であり、 沈殿しないとすると、 [F²] [S²-], [Cd+][s²-] ともに 0.10×1.2×10-2=1.2×10-21 であり,この値は FeSの溶解度積は こえていないが, CdS の溶解度積はこえている。 そこでFeSの沈殿は生じ ないが, CdSの沈殿は生じる。
