- Q: What are the different elements of the same element?
- The same type of body, refers to the same single chemical elements, but the nature is not the same element. The difference in the nature of the allotropes is mainly manifested in the physical properties, chemical properties also have a difference in activity. Such as phosphorus, two kinds of allotropes, red phosphorus and white phosphorus, their ignition points are 240 and 40 degrees Celsius, after the full combustion of the product are phosphorus pentoxide; white phosphorus (P4) is highly toxic, soluble in carbon disulfide, Red phosphorus (Pn) is non-toxic but insoluble in carbon disulfide. Allotropes can be transformed from each other under certain conditions, and this transformation is a chemical change.
- Q: Nutritional characteristics of carbohydrates and inorganic salts in vegetables
- Carbohydrates include sugars, starches, cellulose and pectin substances. Its species and quantity, because of the types of food and varieties are very different.
- Q: Inorganic salt of the inorganic salt function
- Participate in and maintain the metabolic activity of the organism.
- Q: People do not eat salt tears with no inorganic salt
- Salt can also be obtained from the food, can be lack of salt to the row of no salt (tears, sweat, urine salts are the body of the salt) estimated that people are almost dead.
- Q: Why is the inorganic salt left after the burning of the food
- Food contains protein, fat, inorganic salts and water and other substances in the process of combustion in addition to inorganic salts and the rest of the water are burned, and water in the combustion process evaporates. So take the only inorganic salt.
- Q: By balancing the benefits of dietary supplementation with inorganic salts, what are the advantages and disadvantages of taking health care agents?
- Diet supplementation of inorganic salt or the nutritional needs of the human body is the normal diet of human absorption, rather than through deliberate conditioning to mobilize the body's ability to absorb (including deliberately balanced diet), that is, add inorganic salt only conventional diet Yes, no other adjustment supplement is its benefit, that is, healthy people do not need to like non-healthy state as a way to seek additional, this is his advantage.
- Q: Which solvents have some solubility in inorganic salts
- A wide variety of dyes, dissolved complex. The original dyes are organic, but some salt, some metal complexes, some of the larger molecules of the fused ring compounds, some polymer heterocyclic compounds, in some common organic solvents in the solubility is better than disperse dyes Raw dyes and oil-soluble dyes (this is actually the raw material of solvent pigments, strictly speaking, not dyes). There are basically additives in the finished dyes, such as direct dyes, acid dyes, reactive dyes, cationic dyes and other water-soluble dyes will be added inorganic salts, disperse dyes, reducing dyes will be added sulfonate sodium dispersant. In addition, the dye and other chemical products, their purity requirements are generally very low, will allow the presence of certain insoluble impurities. So the organic solvent can not be completely dissolved dye products really is very common or even a normal phenomenon.
- Q: Indicating the organic compounds and inorganic salts in the boiling point, melting point and solubility of what is the difference
- Organic compounds are mainly covalently bonded, the mutual attraction between molecules is very weak, so its melting point, low boiling point, generally insoluble in water and soluble in organic solvents. Inorganic salts with ionic bonding, positive and negative ions electrostatic attraction is very strong, so the melting point, boiling point is very high, usually insoluble in organic solvents and soluble in water.
- Q: A bit tall please help me one!
- China Battery Industry Association executive vice president and secretary general Wang Jingzhong pointed out: "green alkaline alkaline manganese battery products," the introduction of China's alkaline manganese batteries marked the main environmental indicators have reached the world advanced level. This time the introduction of alkaline manganese battery brand, the battery mercury content of 0.0001% below, and not contaminated soil mercury content close. Waste batteries have little impact on the environment. According to the State Environmental Protection Administration on October 9, 2003 announced the "waste battery pollution control technology policy" provides that the waste mercury-free alkaline manganese batteries can be mixed with domestic waste collection and landfill.
- Q: Now need to determine the freezing point of inorganic salt solution, what kind of freezing point instrument is more accurate?
- Because a large branch of antifreeze is with inorganic salt solution.
