(完整版)初中九年级化学第九单元知识点总结(完整版)

第九单元《溶液》知识点 一、溶液的形成 1、溶液 (1 )概念:一种或几种物质分散到另一种物质里形成的均一的、稳定的混合物,叫做溶液 (2)基本特征:均一性、稳定性的混合物 注意:a、溶液不一定无色,如硫酸铜为蓝色、硫酸亚铁为浅绿色、硫酸铁为黄色b 、溶质可以是固体、液体或气体;水是最常用的溶剂,如无说明,默认水为溶剂。c 、溶液的质量=溶质的质量+溶剂的质量溶液的体积工溶质的体积+溶剂的体积(分子间有间隙) d 、溶液的名称:溶质的溶剂溶液(如:碘酒一一碘的酒精溶液) e 、固体、气体溶于液体,液体为溶剂 2、溶质和溶剂的判断 (1)有水,水为溶剂 (2)液体溶于液体,无水,量多的为溶剂 3、饱和溶液、不饱和溶液 (1)概念:在一定温度下,向一定量溶剂里加入某种溶质,当溶质不能继续溶解时,所得到的溶液叫 做这种溶质的饱和溶液;还能继续溶解的溶液,叫做这种溶质的不饱和溶液。 (2)判断方法:看有无不溶物或继续加入该溶质,看能否溶解 (3)饱和溶液和不饱和溶液之间的转化 饱和溶液一不饱和溶液:增加溶剂、升高温度 不饱和溶液一>饱和溶液:增加溶质、蒸发溶剂、降低温度 注:①Ca(0H)2和气体等除外,Ca(0H)2的溶解度随温度升高而降低 ②最可靠的方法是:加溶质、蒸发溶剂 (4)浓、稀溶液与饱和不饱和溶液之间的关系 ①饱和溶液不一定是浓溶液(可能溶解度很小,如饱和的石灰水溶液就是稀溶液) ②不饱和溶液不一定是稀溶液(溶解度很大,即使未达到饱和也已经溶解了大量溶质) ③在一定温度时,同一种溶质的饱和溶液一定要比它的不饱和溶液浓 (5)溶解时放热、吸热现象(根本原因是水解作用和水合作用的热量变化不同) 溶解吸热:如硝酸铵 NH4N0溶解 溶解放热:如氢氧化钠NaOH溶解、浓H2SO4溶解溶解没有明显热现象:如NaCI 二、溶解度 1 、固体的溶解度 (1) 定义:在一定温度下,某固态物质在100g溶剂里达到饱和状态时所溶解的质量 四要素:①条件:一定温度②标准:100g溶剂 ③状态:达到饱和④质量:单位:克 (2) 含义: 20 C时NaCI的溶液度为36g含义: 在20C时,在100克水中最多能溶解36克NaCI或在20C时,NaCI在100克水中达到饱和状态时所溶解的质量为36克 (3) 影响固体溶解度的因素:①内因:溶质、溶剂的性质(种类) ②外因:温度

第9单元-课文翻译及课后练习答案

Unit 9 Holidays and Special Days In-Class Reading A Merry Christmas 参考译文 快乐的圣诞节还吃吗? 帕特里克·布伦顿 1你可能知道merry 有两层意思:快乐和醉酒。如果你像许多英国人那样,那么你的圣诞节将会是一个喝酒的而不是宗教的节日。从12 月初直到1 月份的第一周结束,整个圣诞节期间,你会花很长时间与朋友、亲戚和同事喝酒。无论身处酒馆喧闹友好的气氛中,还是置身于他人安宁舒适的家里,你都会一小口一小口地喝个不停。 2如果圣诞节前夕在皮卡迪利或牛津大街上行走,你就会看到大把大把的钱花在电子游戏、瓶装烈性酒、昂贵的服装、激光唱片、磁带、照相机以及大量的奢侈品上。如果圣诞节前夕,到伦敦东区几个镇的主要街道上走一走,你就看不到(有人)大把大把地花钱买礼品。假如你有钱或者你不怕负债,你就会加入到圣诞节所体现的炫耀性消费的行列中去。如果你没钱,你会感到伤心失望,因为不能给心爱的人你想给的礼物。 3圣诞节应该是对他人表示爱心和良好祝愿的时候。它应该是为那些没有我们那么幸运的人做善事的时候。然而,当我们坐下来吃圣诞大餐的时候我们想到过别人吗?当然没有。我们只顾忙于品尝圣诞节的美味佳肴。我们只顾忙着想知道我们送给别人的礼物是同别人送给我们的一样好,还是比他们送的更好。我们忘了顾及那些生病的和无家可归的人。整个圣诞节基本上丧失了基督精神这一概念——我相信如果基督看到在以他的名义进行这样的庆祝活动,他一定会很痛苦。 4因此,我反对过圣诞节——我同意斯克鲁奇的看法:“这全是挂羊头卖狗肉。”如果我们还要继续以这种铺张浪费、愚昧无知的方式庆祝的话,那么让我们诚 实一点,就把它叫做“吃喝周”——让我们剥掉伪装,别去说什么圣诞节是“表达良好祝愿的时节”。让我们正视它吧,圣诞节是一个失去了原来意义的节日。 不仅仅为小孩? 林恩·奈特 5最近,一位涉世颇深的妇女羞怯地告诉我,她把所有的礼物一直存到圣诞节的早上,然后坐在床上打开礼物,就像个孩子一样。她原以为我会笑话她,

最新人教版九年级英语第九单元知识点(1)

定语从句 I prefer music that has great lyrics. I love music that I can sing along with. I like music that I can dance to. . Role-play 1. Hmm, depends which movie. 1) 本句省略了depends前的主语it和which movie后的从句部分we’ll watch,这是典型的口语表达形式。在口语和非正式场合,为保持语言简洁明了,交流者往往会省略彼此所知或逻辑上可明确推断的内容。 例如:Anything I can do for you? 我能为您做些什么吗?(省略句首部分Is there) Please hand me one of those books; I don’t care which. 请把那些书递给我一本,不管哪本都行。(省略句尾部分you hand me) 2) It depends (on) who/ what/ how/ whether…是一个常见句型。当depend后接疑问词及含有疑问词的短语和从句时,口语中会省略depend后的介词on,以求话语简练。 例如: It depends what day you catch me, and at what time of day. 这取决于你哪天见我,以及见我的时间。 Well, as for this matter, I can’t decide for now. Depends whether or not your dad will say yes. 嗯,这件事我现在决定不了,取决于你老爸是否会同意。 2. I just want to laugh and not think too much. 这句话中的to laugh和not think too much均为动词不定式,但后者在not和think之间省略了to。英语语句中当多个不定式结构并列使用时,to出现在第一个结构中,后面的往往会省略。再如: She likes to sing, dance and hang out with her friends. 她喜欢唱歌、跳舞、与朋友们外出消遣。 3. I prefer music that has great lyrics. 句中的prefer意为“更喜爱;更喜欢”,后可接名词、v.-ing形式或动词不定式。 如:I prefer the white bag. 我更喜欢那个白色的包。 Tony prefers staying / to stay at home on weekends. 托尼更喜欢周末待在家。 此外,prefer还可用于句型“prefer ... to ...”中,意为“喜欢……而不喜欢(胜过)……”。如:Linda prefers apples to pears. 琳达喜欢苹果而不喜欢梨。 I prefer reading books to watching TV. 我喜欢阅读而不喜欢看电视。 4. I suppose I’ll just listen to this new CD I bought. 仔细观察下面例句中suppose的用法和意义,然后补全结论部分所缺的内容。 a. We are supposed to get there on time. b. I suppose she will be back next year. c. —Do you suppose he will agree? —Yes, I suppose so. / No, I suppose not. a. We are supposed to get there on time. (1)观察例句a可知,“被期望/要求做某事”或“该做某事”可用 __________________ 结构表示,含有必须、应该做某事之意,相当于should。 b. I suppose she will be back next year. c. —Do you suppose he will agree? —Yes, I suppose so. / No, I suppose not. (2)例句b中“suppose +that从句”意为“猜测/假定……”,that可以省略,若为否定句,
