What industries are involved in high school chemistry? What is the difference between high school ch

It depends on the difference in each place, but the main ones in the midterm include.

Chlor-alkali industry (electrolysis of saturated brine).

It is necessary to pay attention to the electrolytic poles, the chemical equation of chlorine, and also the derivatives of chlorine obtained in the chlor-alkali industry, such as bleaching powder, and bromine and iodine produced from chlorine.

Sulfuric acid industry. What needs to be paid attention to in the sulfuric acid industry is the conservation of s, and the equilibrium involved in the conversion of sulfur dioxide to sulfur trioxide, (@合成条件的选择@@@次要的是在每个反应在什么反应容器中进行. Environmental pollution is often involved in the sulfuric acid industry.

Ammonia industry.

Its main principle is still similar to that of the sulfuric acid industry, and the main reason is also because of the selection of synthesis conditions, which is very important when synthesizing, and the purpose is to get faster and more products under different conditions.

Silicate industry.

This exam is relatively unfocused, mainly learning some raw materials such as cement, glass and other synthetics, as well as some reaction equations about silica that will be involved.

Organic industry...

The organic industry is all about oil smelting

There is no chemical equation for this kind, the main thing to understand is that the oil obtains the different products required by fractionation, and pay attention to the fractionation device (which can be understood similarly to the distillation device area).

In high school chemistry not every element, every substance needs to be considered for his industry, it is important to learn a whole networked knowledge structure, in the early stage of the establishment of this structure, it is necessary to be familiar with the learning of substances (elements) through chemical properties.

It is possible to list the chemical properties and then discover the relationship between the various elements.

Secondly, we can work the periodic table and the periodic law by contrasting, and pay more attention to the law of the change of the properties of the elements (what causes this law) and the differences that arise after the change, as well as the similarities between them.

Inorganic. Chlor-alkali industry 2NaCl+2H2O=2NaOH+Cl2+H2 brine should be refined.

Sulfuric acid industry 4FeS2+11O2=2Fe2O3+8SO2 The concentrated sulfuric acid in the SO2 absorption tower is fed in from below, and the absorption liquid is concentrated.

Nitric acid industry 4NH3 + 5O2 = high temperature and high pressure catalyst = 4 O + 6H2O 2 O + O2 = 2 Nuo2

3no2+h2o=no+2hno3

Smelting of iron Fe2O3+3CO=High temperature=2Fe+3CO2 reversible reaction.

Organic. Soap Industry (C17H35COO)3C3H5 + 3NaOH (solution) === 3 C17H35COONA+C3H5(OH).

Petroleum industry.

Inorganic industry: silicate industry, chlor-alkali industry, nitric acid industry, sulfuric acid industry, iron smelting.

Organic industry: petroleum industry.

As a sophomore majoring in chemical engineering. Although I didn't study chemistry, there are similarities between the two. For me, I think chemistry is a good major.

Whether it is the opening of the major or our future employment prospects, the chemistry major is a good major.

The professional courses of chemistry are richChemistry majors can be inorganic chemistry and experiments, analytical chemistry and experiments, organic chemistry and experiments, physical chemistry and experiments, structural chemistry, instrumental analysis and other basic chemistry professional disciplines.

In addition to mastering the basic knowledge of specific sciences, the chemistry major also cultivates students' ability to think critically, experiment with techniques, interpret observations, and express their thinking clearly. As a discipline with a long history and vitality, its achievements are an important symbol of social civilization.

There are many employment directions for chemistry majors, good employment prospects Chemistry involves many aspects of knowledge, learning chemistry can work in many positions, the salary will not be low, and the future development prospects will be very good, most of them are engaged in R & D engineers, laboratory technicians, sales engineers, experimenters, high school chemistry teachers, quality inspectors and so on.

After graduation, there are more opportunities to work in Shanghai, Beijing, Guangzhou and other cities. After all, chemistry is a basic science discipline, mainly theoretical research, and it is difficult for undergraduates to achieve great success.

Recommended schools: Tianjin University, Tsinghua University, East China University of Science and Technology, Zhejiang University, Dalian University of Technology, Beijing University of Chemical Technology, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, South China University of Technology, Nanjing University of Technology, etc.

After the tempering of the college entrance examination, it is recommended that you do not only look at the majors and colleges, but also know that the focus of the majors of different colleges and universities is different, and you should take a look at the admissions brochure of the colleges and universities you want to apply for to consult the admissions teachers, or you can be more sure. Finally, I hope you can be admitted to your ideal school and find a major that suits you.
