氯化氫的性质是什麽？　
物理性质：氯化氫无色，熔点-114.2度，沸点-85度。有窒息气味，对上呼吸道有强烈刺激，对眼睛、皮肤、粘膜有腐蚀。比重比空气大，碰到潮湿的空气会产生白雾，容易溶解于水。

化学性质：氯化氫、腐蚀性不燃性气体，不与水反应但易溶于水，在空气中多以盐酸烟的形式存在。易溶于乙醇和乙醚，也易溶于其他多种有机物的水中，在25℃和1个大气压下，一个水坑可以溶解503体积的氯化氫气体。干燥氯化氫的化学性质很惰性。碱金属和碱土金属可以在氯化氫中燃烧，钠燃烧时发出明亮的黄色火焰。

氯化氫气体溶解在水中生成盐酸，小瓶打开时总是形成空气中的小水滴和盐酸雾。工业盐酸经常微黄色，主要是由于氯化铁的存在。氨水常用于检查盐酸的存在，氨水与氯化氫反应生成白色的氯化铵微粒。氯化氫有強偶極，與其他偶極發生氫鍵。

Then suddenly all surmise and speculation was expunged from his mind, for no longer the clack of the typewriting machine came from next door. He heard the stir of a chair pushed back, and the rattle of a door handle. Norah was coming; who was of greater concern than all his thoughts about her.... And he was going to give her no quarter: she would have to introduce the subject of her feelings with regard to his niggardly hospital-subscription herself. He knew something of her pride from the affair of the book-plate, and he longed to see her take that armour off. "Found anything out, mate?" another officer asked. It is not intended to recommend writing down rules or tables relating to shop manipulation so much as facts which require remark or comment to impress them on the memory; writing notes not only assists in committing the subjects to memory, but cultivates a power of composing technical descriptions, a very necessary part of an engineering education. Specifications for engineering work are a most difficult kind of composition and may be made long, tedious, and irrelevant, or concise and lucid. From a quite small garden close to the palace a bronze gate with three medallions of lilies in high relief, of marvellous workmanship, opens on the Pearl Mosque, exquisitely white, at the end of its forecourt of immaculate pavement enclosed by a marble balustrade. Three polished and shining domes are supported by columns of snow made of a hard white marble, scarcely broken by [Pg 218]ornament, and carrying a roof hollowed into three vaults. The rings are still to be seen on the marble walls outside, to which, when the great Mogul came to prayer, curtains were attached made of gold net and spangled with diamonds and pearls. Sandy’s birthday dawned hot, but clear, with a good, steady south wind blowing. “Jeff calls it a ‘jinx’—a ‘hoodoo’,” responded Dick. “But the chef would discover it—they couldn’t be left there!” She was sitting in her room, sewing. Of late she had become domesticated, and she was fading under it. He had seen it already, and he saw it more plainly than ever just now. She looked up and smiled. Her smile had always been one of her greatest charms, because it was rare and very sweet. "Jack," she greeted him, "what have you done with the bread knife you took with you, dear? I have been lost without it." "Neither," drawled Cairness. "But Mrs. Lawton, here, has been good enough to tell me that you have known the exact truth about the Kirby massacre ever since a week after its occurrence, and yet you have shielded the criminals and lied in the papers. Then, too," he went on, "though there is no real proof against you, and you undoubtedly did handle it very well, I know that it was you that set Lawton on to try and bribe for the beef contract. You see your friends are unsafe, Mr. Stone, and I have been around yours and Lawton's ranches enough to have picked up a few damaging facts." The prince found in the Opposition in England the most unfortunate fosterers of his unfilial temper. Pulteney, Wyndham, Chesterfield, Carteret, Cobham, and, worst of all, Bolingbroke, became his associates, and the frequenters of his house. Fast ripening into a pattern of unfilial popularity under such influences, possessing some accomplishments, and a desire to stand well with the people, he married in April, 1736, Augusta of Saxe-Gotha, a princess of so much beauty and good sense, as might have reclaimed many a nature; who seems to have at least won the heart of her husband from his former romantic passion. It was an ominous circumstance, however, that the address of congratulation on this occasion was moved, not by the king's own Ministers, but by the king's own Opposition. Pulteney was the mover, and it was supported by two young men who that evening made their first speeches, and in them burst suddenly forth with that splendour which was destined to grow transcendent through many years. They were Pitt, afterwards Lord Chatham, and Lord Lyttelton. The Deacon had just remembered that he had not seen that individual for some little time, and looked around for him with some concern. It was well that he did. Shorty had come across the haversack that the Deacon had brought, and it awakened all his old predatory instincts, sharpened, if anything, by his feebleness. Without saying a word to any body, he had employed the time while the Surgeon and Deacon were in conversation in preparing one of his customary gorges after a long, hard march. He nearly succeeded. There was silence, in which a coal fell. She still stood with her arms outstretched; he knew that she was calling him—as no woman had ever called him—with all that of herself which was in his heart, part of his own being. "Why, my lord," said Luke, in reply to De Boteler's interrogatory, "there is hardly a free maiden in the parish that would not have been glad of Stephen; but, though I have never seen her, I am told this wife of his is the comeliest damsel between this and Winchcombe: and, besides, she is not like a common nief—and then, my lord, she is the sister of the good monk John."
