学习了煤化工后的收获
通过学习煤化工工艺,使我更加深刻的认识到了煤化工对生活,生产的必要性。更加深入的了解了化工企业生产的基本原则与基本规程。
一篇关于化工专业英语这门课程收获的英语作文
Chemistry is the study of the structure of matter, composition, properties and changes in rules and disciplines of life is full of chemistry, the patented invention in the world, 20% of the chemical concerned; Developed countries engaged in the research and development of scientific and technological personnel, the chemical and chemical experts accounting for about half; it is the test we want to test, and it is difficult to learn, but very simple.
Studied chemistry first understand the chemistry, the culture of fun for chemistry, when you had a fun, learning chemistry will no longer be a problem. Chemical established an experimental basis on the subject, so we often have access in their chemistry class many interesting experiment, but not just so wonderful chemistry. If you're really stuck chemistry go, you can not help but use chemical way of thinking, but the chemistry is not the lack of passion, when you have this kind of warm chemistry, when the use of chemical as a habit, not only locate the chemistry in the study, but in life. Then you will find that chemistry is so interesting.
Once you have interest in, but also a method. I think chemistry is very simple to learn, first of all to the backing of the full back, and we must do better after back problems, make the title key is to master skills, master a do question the method is more useful than doing one hundred questions, not to ask for.
I studied chemistry has been a year, and in the chemical after school feel very small, do not know too many things, but the chemistry is really an interesting subject, do not know if you have that feeling.
如何学好化工原理?
主要学习化学工程中单元操作的基本原理,平时学习时要把基本概念理解清楚,注意把所学的原理与一些工程实际结合起来,另外多做好课后的习题,加深理解原理.化工原理很重要,是化工学科的基础课程,它是学好其它化工课程的前提,一定下工夫学好它,另外将来考研也要考的.
通过化学课程的学习,我们收获很多.收获一:生活中处处有化学,通过学习已经知道:(1)铁生锈、食物腐
收获一:(1)铁生锈、食物腐烂是因为空气中有氧气;雨雪等自然现象证明空气中有水;
故填:氧气或者O2;水或者H2O;
(2)天然气具有可燃性,所以我们可燃烧天然气做饭;
故填:可溶性;
(3)空气中含量最多的气体是氮气;
故填:氮气;
(4)空气中可能形成污染的物质包含有害气体和粉尘,有害气体主要为SO2、NO2、CO、O3;
故填:可吸入颗粒物(烟尘、粉尘);SO2、NO2、CO、O3;
收获二:(1))“酒香不怕巷子深”的事实可以说明分子在不停地运动的性质;
故填:分子在不停地运动;
(2)分子和原子的主要区别是在化学变化中,分子可以再分,而原子不能;在加热氧化汞“HgO→Hg+O2”这样一个化学反应中,发生变化的微粒是氧化汞分子,没有发生变化的微粒是氧原子和汞原子;双氧水分解生成了水和氧气,但双氧水不具有水和氧气的性质,原因是分子是保持物质化学性质的最小粒子,过氧化氢分子只能保持过氧化氢的化学性质(或水的化学性质由水分子保持,氧气化学性质由氧分子保持);
故填:在化学变化中,分子可以再分,而原子不能;氧化汞分子;氧原子;汞原子;分子是保持物质化学性质的最小粒子,过氧化氢分子只能保持过氧化氢的化学性质(或水的化学性质由水分子保持,氧气化学性质由氧分子保持);
收获三:(1)实验室最常见的一种加热仪器是酒精灯,熄灭该仪器时应该灯帽盖灭;
故填:酒精灯;灯帽盖灭;
(2)量取一定量的液体应该用量筒和胶头滴管;
故填:量筒;
(3)玻璃棒的作用有搅拌、引流、转移固体;
故填:搅拌、引流、转移固体;
(4)①某同学用过氧化氢溶液制取氧气时,发现收集氧气的速率比较慢.可能的原因是没加催化剂/过氧化氢浓度过低/装置漏气;
故填:装置漏气;
②某同学完成过氧化氢溶液制取氧气的验证实验时,如图所示,看到试管内有大量气泡冒出,但是带火星木条并没有明显复燃,可能的原因是该反应放热,产生的氧气中混有大量水蒸气.
故填:该反应放热,产生的氧气中混有大量水蒸气.
学化工学科导论课目的
对于考生来说化工学科的导论一点儿用都没有,导论主要是介绍这门学科适用的范围,主要学习的内容。类似于这门学科的介绍。
