What is it like to be good at chemistry?

Aunt: Open the window to turn on the air conditioner, otherwise it will be fluorosis, and it is read as "Buddha" poisoning, you must know that freon has not been used as a refrigerant for many years! And if the air conditioner freon leaks, it's not a simple air conditioner headache or something!

Freon can cause severe hypoxia, dizziness, nausea, and coma. Air conditioning disease is caused by poor air circulation, and it is true that you need to open some windows to turn on the air conditioner, but it is not because of fluorosis. Whenever I talk about this topic, I can only smile and nod my head: "Okay, okay, auntie, I must open the window, I know that it will be fluorosis."

The classmate went to the school supermarket and saw Dabao, and the classmate tried to pretend: "Now a lot of skin care products have added some strange things, you look at Dabao, it's useless to add that sod." Do you know what kind of enzyme that SOD is.

Hey, what's the enzyme? Me: "Superoxide dismutase."

Don't say it's useless, it's really useful. "SOD is also in our body, decomposing superoxide that is harmful to us, and it is used in ** to prevent oxidation and aging. So don't discriminate against Dabao.

After studying chemistry, I felt the urge to study the atomic bomb on my own.

A friend traveled to Yunnan and came back to buy a small bracelet, saying that it was silver, and I asked, 10g actually cost 400 yuan! I cautiously asked, "Do you know how much silver is worth now, my dear?"

She said she knew, but it was "medicinal silver", and the salesperson took the medicinal silver and scratched it on the paper with lipstick, which was black and particularly effective. I'm speechless. There's sulfur in the lipstick!

Sulfur and silver react with black silver sulfide! Friend, why don't you believe me, next door to your physics competition back then was me in the chemistry competition! I feel sorry for my friend's money.

Learning chemistry is the foundation of understanding life, learning chemistry is the foundation of understanding the world, learning chemistry philosophy is the foundation of progress, and language can be improved! Learn mathematics, physics and chemistry well, and you are not afraid to go all over the world. There is no truth to this statement. Mathematics, physics and chemistry will be reflected in daily life.

If you are good at chemistry, you should be accustomed to explaining many things in life from the perspective of chemistry.

Female classmate: "I think sunscreen and foundation are particularly bad for **, they are full of heavy metals and colorants." It is better to apply milk to your face.

Me: "Milk macromolecules can't be absorbed, and it's basically useless." As for sunscreen foundation?

It's okay, good people don't need it, like you. ”

My mother especially likes to say, girls should not use cosmetics when they are young, they all contain lead, and do not use functional skin care products that contain hormones, if this is the case, how many women in the world have necrosis of the femoral head or hormone disorders and become pigs! Many babies tell me that cosmetics contain lead and mercury, but there are standards. Dose aside, it's all hooligan to talk about toxicity.

Also, expensive cosmetics are still reassuring, babies don't be greedy to buy thirty or fifty three no lipsticks.

The roommate eats turkey noodles, which is so spicy that it tears, so spicy that it is trance, and so spicy that it is incoherent. Me: "Drink some cold water, or whole milk." Roommate: "I want to drink hot water, which of you has hot water, you need to be hot." ”

It's really super easy to ask all kinds of questions, it's like hanging up, and the experience is super good.

Every time I see chemical fertilizer, I think about what I use, how many degrees of heat it is synthesized, these are not difficult for me.

It taught me how to kill silently (funny).

That is, when you see what your family eats every day, you will associate them with chemistry.

At the beginning of employment, it is still a little difficult to reincarnate, because this major is applicable to a wide range of fields, such as pharmaceutical cleaning, medicine, scientific research, and some chemistry-related industries, but this also gives people a feeling of unprofessionalism.

Some of our friends are those who do testing, research and development of medical and chemical formulas, those who work in scientific research, those who work as application engineers in the company, those who go abroad, and those who become teachers.

As long as you enter an industry, you will slowly show your strengths.

It is still very promising to develop in the biodiagnostic reagent industry now.

In short, in a word, the professional counterpart is poor, which will bring some difficulties to the initial employment, but in the long run, the major is still good.

<> Major: Biochemistry, which generally refers to chemical biology, is an undergraduate major in ordinary colleges and universities in China. Chemical biology mainly studies the life phenomena and life processes in biology through the theory and methods of chemistry, including the occurrence and development of diseases, the intervention of artificial drugs in the pathological process, etc., such as the causes of influenza and the development of anti-cancer drugs.

Main Course of Study:

The main courses studied in this major include "Bioinorganic Chemistry", "Bioorganic Chemistry", "Cell Biology", "Molecular Biology", "Chemical Biology", "Bioinformatics", etc.

Where to work after graduation:

After graduation, students majoring in chemistry and biology are suitable to engage in research and teaching work in scientific research departments and colleges and universities. It is suitable for applied research, scientific and technological development and management in chemical, pharmaceutical, medical, biochemical and pharmaceutical, bioengineering, inorganic new materials, chemical, light industry, energy and other industries, as well as factories and mining enterprises, undertakings, technologies and administrative departments.

Supplementary Information: Chemical biology is the science that studies the chemical basis of life processes. The occurrence and development of diseases is the interference and destruction of life processes by the children; The prevention and treatment of drugs is the intervention of the pathological process.

Chemical biology provides an indispensable theoretical basis for the discovery of new drugs by using chemical theories and methods to study the chemical basis of life phenomena and life processes, and by exploring the ways and mechanisms of intervention and adjustment of disease occurrence and development.

1. I like to do experiments.

Students who are familiar with the course of chemistry know that although chemistry says that it is necessary to memorize the knowledge points, it is impossible to understand the principle without passing the experiment.

2. Very patient.

Whether it is in the process of doing chemistry experiments or solving chemistry problems, we need to have very good patience, especially when studying chemistry comprehensive problems, we need to work hard.

If you are very anxious and impatient, but you can't find the knowledge point of this problem, even if we haven't encountered this type of question, the patient students will calmly analyze and solve it.

3. I like to do questions.

Don't look at chemistry as one of the science subjects, you don't have to practice repeatedly, the top students you know are not easy to be, but you don't see the effort they put in behind the scenes.

In fact, chemistry problems also need practice to make perfect, those chemical equations seem to be ever-changing, in fact, it still has a certain law. When you do the problem a few more times, you will find that all chemical equations have a commonality, so you can easily deal with any difficult problem.

1. Are the employment prospects of chemistry majors good?

The employment prospects of graduates majoring in medicinal chemistry are still good, especially the employment of male students is more optimistic, in the field of pharmacy, purely from a technical point of view, medicinal chemistry is the most promising, and the salary is relatively high. Graduates of this major are employed in various pharmaceutical research units, organic chemistry research institutes, pharmaceutical production enterprises and drug administration institutions, and can also be engaged in teaching in colleges and universities.

2. Is it easy to find a job in chemistry?

This major is very good, and the employment range is also very wide. As the saying goes, applied chemistry is a ghost everywhere. However, you have to be fully mentally prepared to study this major, and there are a lot of experiments in the first and second years, and it takes a lot of time to take organic experiments as an example.

However, it is still more fun to do experiments, and our major truly embodies the "application of learning" to cultivate their hands-on ability.

Employment prospects are one thing, the most important thing is the personal knowledge base and skills and future planning, the employment of undergraduates is average, highly educated talents should be more popular, and the employment prospects of biochemistry majors are relatively similar, such as bioengineering.

3. Employment direction of chemistry major.

Teaching profession. Suitable for: Chemistry science students, such as undergraduate students in the normal direction.

This type of student has more educational modules than engineering students in the training program. It is also a good choice to study pedagogy and pedagogy and become a teacher!

Tips: Because chemistry is studied from the third year of junior high school, undergraduate students can at least go to the third year of junior high school to teach.

Researchers. Suitable for: Chemical engineering students, such as materials chemistry, applied chemistry, chemical engineering and technology (chemical engineering) undergraduates.

Chemistry research is also a common choice. Many undergraduates follow their teachers to do experiments in the laboratory during their undergraduate years, which has advantages for future research and research. In the future, the salary of working in the graduate school is also excellent.

Factory workers.

Suitable for: Chemical engineering students, such as materials chemistry, applied chemistry, chemical engineering and technology (chemical engineering) undergraduates.

Especially for chemical engineering students, the school will also let students go to the factory for internships during their time at the school. Of course, if you do well during your internship, you may be able to stay in the job!

The mass ratio of iron to oxygen is 21: 8, 21 grams of iron 3 8 mol; 8 grams of oxygen moles, therefore, the ratio of iron to oxygen is 3:4

Because it happens to be the symbol fe3o

4 The quantity ratio of the substance.

then the ratio of the item is arbitrary!

And feo, and fe2o

3. You see feo fe2o

3, isn't it exactly 3:4?

So feo fe2o

3. The ratio of the amount of matter is 1:1
