Who understands basic medical chemistry and what medical chemistry is

1. False. The buffer capacity of the buffer solution depends on the total concentration of the buffer solution and the buffer ratio.

2. False, although the degree of dissociation has increased, the overall concentration of the solution has decreased.

3. Yes, the vapor pressure of the water will drop after the glucose dissolves, resulting in a decrease in the freezing point and the melting of the ice!

4. False, the polarity of molecules with different atoms is determined not only by the electronegativity of the element (the polarity of the bond), but also by the spatial configuration of the molecule, such as CO2 and SO2, although both have polar bonds, however, the CO2 molecule has a linear structure, the polarity of the bond cancels each other, and its positive and negative charge centers of gravity coincide with each other, so CO2 is a non-polar molecule.

5. Yes, obviously, the stability constant!

6. False, hydrogen bonds are saturated and directional, and their strength is related to the electronegativity of the element.

7, right. 8. Yes, the conclusion can be drawn from the Nernst equation.

9. Yes, the principle of the battery.

10, right. 11, right.

12. Yes, the ion product constant of water is a fixed value.

13. False, the standard molar enthalpy of elemental matter in the steady state is zero, c h m° is not zero, and the molar entropy of the perfect crystal of pure matter is zero at 0k, so f g m° is not zero either.

14, right. 15. False, the solubility product of something is constant at a certain temperature, and whether it is dissolved depends on the reaction concentration quotient qc, when qc > ksp, a precipitate is generated, which is a supersaturated solution.

16. False, there is a salt effect.

17. Yes, when the buffer ratio of the buffer solution is constant, the pH value of the solution is also constant. The buffer capacity of the buffer solution depends on the ratio of the total concentration of the buffer solution to the buffer ratio.

18, right, the square of the wave function represents the probability of an electron appearing per unit volume somewhere in space.

19, wrong, plus conditions.

20. Yes, the absorbance of the colored solution increases with the increase of the concentration of the solution, so the absorbance is proportional to the concentration of the solution.

Medical chemistry is a medical school of clinical medicine.

Medical Laboratory Science, Medical Imaging.

This course refines and integrates the chemical knowledge required for higher medical education, such as solution theory, regularity of chemical reactions, basic knowledge of material structure, chemical analysis methods, properties and applications of organic compounds.

Medical Chemistry:

1) Refers to biochemistry.

In the early stage of its development, it was used in the field of chemical research in medicine, and later it referred to the research in the field of polymer chemical mechanisms, mainly in living organisms.

2) Also known as medical chemistry, it refers to one of the 17th-century medical schools that mainly explained life phenomena from the chemical aspect, and established a medical system based on this viewpoint, contrary to physical medicine. This faction was represented by Paracelsus, He-Lmont, Sylvius, and used code words such as "acid and base" and "fermentation" with very different meanings than those of today. Both chemical medicine and physical medicine were opposed to the views of the vitalists of the time who explained life, and contributed to the advancement of life science research.

Medical Chemistry is one of the chemistry textbooks for medical majors in medical colleges.

Medical chemistry is a professional basic course in clinical medicine, medical laboratory science, medical imaging, nursing and other majors of the School of Medicine, which refines and integrates the chemical knowledge of solution theory, the regularity of chemical reactions, the basic knowledge of material structure, chemical analysis methods, the properties and applications of organic compounds and other chemical knowledge required for higher medical education.

2) Also known as medical chemistry, it is one of the 17th-century medical schools that focused on explaining life phenomena from the perspective of chemistry and establishing a medical system based on physical medicine. This faction was represented by Paracelsus, Helmont, and used code words such as "acid and alkali" and "fermentation" that had very different meanings than they do today. Both chemical medicine and physical medicine were opposed to the views of the vitalists of the time who explained life, and contributed to the development of the research of the life sciences.

Medical Chemistry is one of the chemistry textbooks for medical majors in medical colleges.

Medical chemistry is mainly involved in imitation of the plexus and biochemical liquid production beam pharmaceutical industry, biochemical detection of diseases, biochemical engineering**.

Chemistry is a kind of natural science, mainly at the molecular and atomic level, to study the composition, properties, structure and change laws of matter, and to create new substances (the essence is molecules that do not exist in nature).

The world is made up of matter, and there are two main forms of change: chemical and physical changes (and nuclear reactions).

Chemistry plays an important role in our understanding and use of matter.

Different from particle physics and nuclear physics, which study smaller scales, the basic properties of elements, molecules, ions (clusters) and chemical bonds studied in chemistry are the microscopic natural laws that are most closely related to the matter and materials in the macrocosm of human existence.

The universe is composed of matter, and as an important bridge between the microcosm and macrocosm of the material world, chemistry is one of the main methods and means for human beings to understand and transform the material world. It is a discipline with a long history and full of vitality, which is very closely related to human progress and social development, and its achievements are an important symbol of social civilization.

To put it simply, the general source of the acid-base neutralization reaction is the reaction of a stronger BAI acid with a stronger base to form a weaker acid and a weaker base. zhi

If phenol DAO is dissolved in sodium bicarbonate, that is to say, phenol can react with sodium bicarbonate to form sodium phenol and carbonic acid. However, phenol is weaker acidic than carbonic acid, and sodium bicarbonate is weaker alkaline than sodium phenol, so the reaction will occur in reverse, that is, phenol cannot be dissolved in sodium bicarbonate.

If it is more complicated, it is necessary to consider the acid-base constant in terms of thermodynamics. The acid constant of phenol is, and the acid constant of carbonic acid is, then the reaction constant of phenol and sodium bicarbonate can be calculated as, that is, when the concentration of phenol and sodium bicarbonate in the solution is 1mol l, then the product of the concentration of sodium phenol and carbonic acid is, for example, the concentration of both or the concentration of sodium phenol is 1mol l, then the carbonic acid concentration is.

Because phenol is weaker acidic than carbonic acid, if it reacts with sodium bicarbonate, carbonic acid should be generated, which does not conform to the law of metathesis.

Phenol is very acidic and can only react with strong bases.

Basic complex chemistry is the basic system of medicine, the two have a close relationship, chemistry in medicine is the most embodied is that chemistry mainly studies the properties of substances and molecules, and really reveals the mystery of life from the molecular level, every life phenomenon is the embodiment of thousands of biochemical reactions, so medicine and chemistry are closely related.

For example, digestive problems in medicine have an acid-base balance relationship from a chemical point of view. And the process of food digestion is a process of chemical decomposition.

There are many more examples.

The main thing is that the laboratory department of the hospital has a lot to do with chemistry.

1. For the electric pair 2H+ +2E- = H2, in pure water = standard + lg[H+] 2* = + lg[10 -7] 2 =

2. Wrong. The iodine ion is in a reduced state, so as its concentration increases, the electrode potential decreases.

3. According to Henderson's formula, the buffer solution of [oh-] = kb* [configuration base concentration configuration acid concentration] = 10 *1 1 = 10 mol l, then poh = , ph = 14-poh = .

4. When titration is halfway, NH3:NH4+ = 1:1 in the solution, so by Henderson's formula, [H+]=ka* [acid concentration alkali concentration] = 10 -14 10 = 10, so the pH is.
