Q:Does the inorganic salt fight the mass spectrum?
Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
Q:Nutritional characteristics of carbohydrates and inorganic salts in vegetables
Inorganic salts are absorbed and utilized by crops in the soil. Carbohydrates are composed of carbon (C) and water (H20). Each person's body contains carbohydrates.
Q:What are the main physiological functions of inorganic salts?
enzyme composition and activator
Q:What is the disease of inorganic salt crystals?
But if the urine turbidity, but also accompanied by fever, low back pain, increased frequency of urination and other phenomena, there may be inflammation of the urinary system, should go to the hospital for timely diagnosis and treatment of doctors.
Q:What is the relationship between inorganic salts and minerals?
Generally speaking, inorganic salts, including minerals, inorganic salts are not minerals. Some inorganic salts can be soluble in water and some can not, the vast majority of minerals do not dissolve in water, otherwise the rain on the rocks are not dissolved Is it gone?
Q:what is the function of salts in DNA extraction?
DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.
Q:Why is sodium chloride(salt) an inorganic compound?
For the best answers, Organic chemistry, branch of chemistry dealing with the compounds of carbon. While it is only the fourteenth most common element on earth, carbon forms by far the greatest number of different compounds. Organic chemistry is of vital importance to the petrochemical, pharmaceutical, and textile industries, where a prime concern is the synthesis of new organic molecules and polymers. Compounds containing only hydrogen and carbon, of which there are many thousands, are called hydrocarbons; the simplest is methane (CH4). In general, a particular type of organic compound, such as an alcohol, aldehyde, ether, or ketone, is identified by the presence of a characteristic functional group of atoms. The functional group is the part of the molecule most responsible for its particular chemical nature. Organic compounds containing nitrogen are of great importance in biochemistry. They generally contain the amine group (NH2). Molecules containing both the NH2 and COOH groups are called amino acids and are the building blocks of proteins AND Sodium azide is the inorganic compound with the formula NaN3. This colourless azide salt is the gas-forming component in many car airbag systems. It is used for the preparation of other azide compounds. It is an ionic substance and is highly soluble in water. It is extremely toxic. Hydrazine is an organic compound without carbon. Carbon di oxide is a inorganic compound with carbon
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:Does the milk contain inorganic salts?
Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element
Q:TRUE OR FALSE: the addition of salts to water will always increase the surface tension of water. explain.?
False. Although inorganic salts will increase surface tension of the water by increasing the attractive forces between water molecules on the surface, organic salts will typically (always?) decrease the surface tension.
