Q:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
Q:Why can quaternary ammonium salts catalyze the heterogeneous reaction between water-soluble inorganic salts and organic compounds
Quaternary ammonium salts have the characteristics of surfactants, with the water phase of the nucleophile in the composition of the ion pair, into the organic phase, thereby promoting the heterogeneous reaction faster 6224
Q:Sodium bicarbonate is not an inorganic salt
Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt
Q:What is the time when the maximum number of inorganic salts is needed
Nitrogen is the basis of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll, enzymes, vitamins, alkaloids and some hormones, etc. Nitrogen is also the basis of genetic material. In all organisms, the protein is most important, it is Often at the center of metabolic activity, which is the primary factor limiting plant growth and yield, and has a significant effect on improving product quality.
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 does inorganic salts affect chemical degradation of organic wastewater
Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.
Q:Milk food rich in nutrition, in addition to containing a variety of inorganic salts which also contain three types of organic energy can be organic
Fat Glucose Protein
Q:What is the relationship between electronegativity and the solubility of a inorganic salts?
The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.
Q:What are the important physiological functions of inorganic salts in cells
Maintain intracellular acid-base balance, regulate osmotic pressure, maintain cell morphology and function. Such as: blood calcium and potassium ions.
Q:RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?
Modern people generally nutrient surplus, not because of the lack of minerals in the water and hurt, there is no such a report in medicine, Moreover, the world's drinking water into million, have been for decades, not because of water No minerals and malnutrition. The human body will not be due to trace minerals in the water and particularly strong, as long as the nutritional balance like the American Medical Journal (American Medical Journal) pointed out: the human body needs minerals from food, Not from drinking water.
