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.

Q: I&#39;m said that with the increase of temperature the inorganic salts will decrease. Will that be correct?: IIRC, it depends on the salt.

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: Chemical formula The longest inorganic salt: The primary stage on the salt, acid salt and so on

Q: Oxide and organic peroxide signs: An organic compound containing -O-O-peroxy functional group formed by replacing hydrogen atoms in hydrogen peroxide with an organic group such as an alkyl group, an acyl group, an aromatic group or the like. Characterized by heating more than a certain temperature will decompose to produce oxygen free radicals, unstable, easy to break down. Chemical production of organic peroxides is mainly used for synthetic resin polymerization initiator, catalyst. In the field of polymer materials, it can be used as a radical polymerization initiator, graft reaction initiator, rubber and plastic cross-linking agent, unsaturated polyester curing agent and spinning grade polypropylene in the preparation of molecular weight and Molecular weight distribution regulator. Environmental pollution in the air under the action of light through the free radical reaction can produce peroxy nitrates compounds, photochemical oxidants in one of the species. On the skin, eyes, mucous membrane has a strong irritant, is an important pollutant in the atmosphere. Such substances are flammable and explosive dangerous goods, the use should pay attention to safety. Generally, the active oxygen content, activation energy, half-life and decomposition temperature were used as the basis of selection.

Q: How too much to eat too much inorganic salt: Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.

Q: What are minerals and trace elements?: 81 species were detected on the basis of the human body. 81 kinds of elements in the body of the arrangement is very tight combination, and more less will not work. Human anatomy found that there are 74 kinds of serum, 54 kinds of brain, 49 kinds of heart, 50 kinds of liver, thymus 18 species. They constitute the most basic unit of the human body, human life, old, sick, dead and all elements related to the body. According to the elements in the human body content is different, can be divided into macro elements and trace elements two categories. Accounting for more than 0.01% of the total body weight of the elements, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, etc., called macro elements; , Zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, etc., known as trace elements. Trace elements in the human body content is really minimal, such as zinc only the total weight of the human body of thirty-three parts per million. Iron is only sixty thousandths.

Q: What are the important physiological functions of inorganic salts in cells: Maintain the living activities of the organism. Such as: magnesium ions are ATPase activator, chloride ion is an activator of saliva enzyme.

Q: Eye acid is how the matter: Massage DIY in our eyes around the four points, at three o'clock, six o'clock, nine o'clock, twelve o'clock position each have a acupuncture point. There are two places in the place where there are two points, one called pupil, one called the eye, that is, Four directions around the eyes. In addition, in the two brows touch the hundred bark to know Du this version of the preservation of this place there are two points called save bamboo, a few points you can use your fingers on the part of the joint rubbing, by a press, have help.
