What are the symptoms when a person is deficient in copper Can you drink Cu NO3 2 solution supplemen

Insomnia. Increased cholesterol in the blood, causing coronary heart disease. Decreased cardiovascular function.

Symptoms such as memory loss, confusion, and unresponsiveness may occur. If the body is deficient in copper, it can cause anemia, arteriosclerosis, increased cholesterol, graying of hair, and loss of skin pigment (vitiligo).

The amount of copper in the human body is 100-200 mg, and it is widely distributed in all tissues and organs of the body. Copper is involved in the hematopoietic process and is the right-hand man of iron, which can affect the absorption, transport and utilization of iron. Copper is also a unique catalyst in biological systems, participating in the synthesis of ascorbate oxidase, tyrosinase, uricase and galactase, and is the active ingredient of more than 30 enzymes such as superoxide dismutase and monoamine oxidase.

Long-term copper deficiency in the human body will hinder various physiological activities and easily produce various pathological changes, which can obviously increase blood cholesterol, triglycerides and uric acid, which can easily lead to coronary atherosclerosis and coronary heart disease. It can also cause anemia, pediatric copper deficiency syndrome and vitiligo. According to a recent survey in the United States, 2 3 people in the United States have symptoms of heart disease due to insufficient copper intake.

In the United States, in the past 30 years, the per capita cannibalistic copper content has decreased significantly, and the incidence of heart disease has increased by 44 during the same period. According to the World Health Organization, heart disease accounts for the first number of deaths worldwide, while the French are the second-to-last deaths. The low mortality rate of heart disease in the French is related to the liver and kidneys of poultry and livestock (especially geese and ducks), which are the reservoirs of copper in the diet of poultry and animals, so the relatively high copper content in the diet of French people shows the importance of copper in protecting the heart.

Unlike iron, the human body does not have a mechanism to store copper, so a certain amount of copper must be consumed from food every day to make up for the copper excreted in the bile. The copper content in cow's milk is low, only 0 02 mg per 100 grams, which is why babies and children who drink cow's milk are prone to copper deficiency. Experts recommend adding pollen to cow's milk in moderation as a way for infants and children to supplement copper.

There is 0 413 mg of copper per 100 grams of pine pollen.

No, soluble copper salts are toxic.

What is the reflection of the calculation?

This reaction is a redox reaction, which is also called a displacement reaction.

It is copper that reduces silver ions to silver elemental matter (copper is more active than silver).

The outer shell of the copper atom is two electrons, and the divalent copper ions are relatively stable, so there are few or no positive monovalent copper ions in the solution. As long as the reaction product is a solution, copper is positive bivalent, which is an experience. Positive monovalent copper is found in oxides or insoluble salts.

This is a displacement reaction because copper is more metallic active than silver, so copper is more likely to lose electrons and become 2-valent copper, displacing silver. Here it has nothing to do with the oxidation of nitrate because no hydrogen ions are provided in this reaction, nitrate does not show its strong oxidation, and the nitrate in this place only shows acidity.

This is a redox reaction, the gain and loss of electrons should be equilibrium, i.e., the change in valency should be equal, in this reaction, ag gets one electron from positive monovalent to negative valence, and there are two ags in total, so two electrons are obtained.

Cu should also lose two electrons so the positive bivalent.

Metallic copper only reacts with the strong acid nitric acid There is no such theory.

Well, I know what you think.

I want to tell you that in high school I wrote a reaction cu in a format similar to this is explicit 2valence.

There is only one chemical formula that I have encountered that CU shows 1valence, and that chemical formula is still not tested for extracurricular knowledge, so when I write a chemical formula that I haven't learned in textbooks, I default to CU 2valence.

The metal is elemental, the valency is 0, and the valency of the reaction with the acid increases, and it becomes normal.

The mixed solution is that AgNO3 does not react with Cu(NO3)2, and the metal that must contain it is silver. When the copper powder is insufficient or the copper powder happens to react completely, only this reaction occurs: Cu + 2agNO3 = Cu(NO3)2 + 2AG, then the only metal filtered out is silver.

When there is an excess of copper powder, the leached metal has residual copper powder in addition to the silver produced by the reaction.

Concentrated or dilute nitric acid has strong oxidizing properties! This is not a simple replacement reaction, it does not conform to that law!

Dilute sulfuric acid provides H+, Cu(NO3)2 provides NO3-, and contains H+ and NO3- in solution, that is, it is equivalent to containing a strong oxidizing acid HNO3.

So the reaction occurs as follows:

3cu + 2no3- +8h+ == 3cu2+ +2no↑ +4h2o

Sulfuric acid provides protons and Cu(NO3)2 provides nitrate ions, which together are equivalent to the addition of nitric acid. Isn't cu and nitric acid a reaction?

Well, level 7, that's right.

The chemical reaction equation is: 3Cu + 8Hno3 (dilute) = 3Cu (NO3) 2 + 4H2O + 2NO

The ionic reaction equation is: 3Cu + 8H+ +2(NO3)- =3Cu2+ +4H2O + 2NO

The chemical reaction equation: Cu + 4Hno3 (concentrated) = Cu (No3) 2 + 2H2O + 2NO2

The ionic reaction equation is: Cu + 4H+ +2 (NO3)- =3Cu2+ +4H2O + 2NO2

The amount of the substance of Hno3 is 1 mole, i.e., the mass is 63g

This one is very simple, I learned it when I went to high school!!

Reaction equation: Fe + Cu (No3) 2 = Fe (No3) 2 + Cu

There are Fe(NO3)2, Cu(NO3)2, and only Cu in the insoluble substance

Yes, Fe reacts in its entirety, and Cu(No3)2 is left, then Fe(No3)2, Cu is generated

There are Fe(No3)2, Cu(No3)2, and only Fe in the insoluble substance

Wrong, the reaction must produce Cu, so the insoluble matter must have Cu, and it cannot be only Fe

There is only Cu(NO3)2 in the solution and Fe in the insoluble matter

Wrong, the reaction must generate Fe(NO3)2 and Cu, so there must be Fe(NO3)2 in the solution, and the insoluble matter must have Cu, and there is only Fe(NO3)2 in the solution, and the insoluble matter is Fe and Cu

Yes, Cu(No3)2 reacts completely, then there is only Fe(No3)2 in the solution, and the insoluble matter is Fe, Cu

There is only Fe(NO3)2 in the solution and only Cu in the insoluble matter

Yes, when the two happen to react completely, Cu(No3)2 and Fe all react, and the product is Fe(No3)2 and Cu

In summary: what may be possible is (

1,4，5

When Cu(No3)2 is excessive, there are Fe(No3)2, Cu(No3)2, and only Cu in the solution

If there is an excess of iron, only Fe(NO3)2 in the solution, the insoluble matter is Fe and Cu just fully reflected, and the solution only Fe(NO3)2 and the insoluble matter is only Cu

1,4,5, because this reaction is, Fe reacts with Cu to form Fe(No3)2, no matter how much is added, there must be Cu generation first, and then as long as Fe is present, it will react with Cu(No3)2, so exclude 2,3 and choose 1,4,5

2 4 5 , mainly to analyze the problem of overdose.

1 4 5 The two substances have a redox reaction, but the amount of reagent is uncertain, and there are three situations: Fe in 1 is not enough, Iron in 4 is excessive, and Iron in 5 is exactly the reaction is complete.
