Q: are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?
Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.
Q: Potassium permanganate is not used when it will bring those hazards?
Potassium permanganate is a strong corrosive agent, when used, do not directly contact by hand, so as not to burn the skin. Only when dubbed a reasonable concentration, can direct contact.
Q: Finished homework, why the neck acid
Because you write homework when the back of the neck will be bent over a long time will acid
Q: What is the important character of Chinese made alkali?
(1) NH3 + H2O + CO2 = NH4HCO3 (2) NH4HCO3 + NaCl = NH4Cl + NaHCO3 ↓ (3) 2NaHCO3 (heating) = Na2CO3 + H2O + CO2 ↑ That is: ① NaCl (saturated) + NH3 + H2O + CO2 = NH4Cl + NaHCO3 ↓ ②2NaHCO3 = Heating = Na2CO3 + H2O + CO2 ↑ Ammonia reacts with water and carbon dioxide to form a molecule of ammonium bicarbonate, which is the first step. The second step is: ammonium bicarbonate reacts with sodium chloride to form a molecule of ammonium chloride and sodium bicarbonate precipitation, sodium carbonate is precipitated because it is less soluble.
Q: Inorganic salt function
Inorganic salts can be used for a wide range of raw materials
Q: Are the inorganic salts mineral and they are soluble in water?
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: Is sulfur simple?
In fact, in the determination of the nature of a substance, the effect of impurities is generally ignored. The reason why hydrochloric acid is a mixture is because its essential composition is water and HCl, both of which are not impurities and sulfur, which is S8 (A kind of sulfur), there is no other necessary ingredients, so it is simple and some occasions, really want to consider impurities, but this will be a clear indication in the name such as copper or copper, copper are simple, Bronze, white copper because of the determination of other ingredients and for the mixture, while the coarse copper although the other ingredients are not sure, is impurity, but because there is a clear name prompt, but also the mixture
Q: General identification method of inorganic salts
Take platinum wire, with hydrochloric acid wet, dipped in the test sample, burning in the colorless flame, the flame that was purple. But a small amount of sodium mixed, must be separated from the blue glass perspective can be identified. 2K ++ [PtCI6] 2- → K2PtCI6
Q: Is all the inorganic salts in the body related to life activities?
Sugar is the most important material for the human body, all the activities of the human body, including learning, walking, digestion and breathing, etc., which are the most important substances in the human body. Consumption of energy (about 70%) mainly from the carbohydrates, fat is the body of the energy material, the protein is the basic material of human cells, but also to provide energy, vitamins are neither the main raw material of the organization, nor the supply of energy Material, but it has an important role in the life activities of the human body; inorganic salts constitute an important raw material of human tissue, water is the main component of cells. Which protein, sugar, fat, vitamins can burn for organic matter, and water, inorganic salts can not burn as inorganic.
Q: What is alkali?
What is the alkali is the ionic compound, the ionization of the anion is hydroxide (OH-), in fact, the oxygen ion acid root (which can compare sulfur and sulfur), and the anion contains only hydroxide. (Such as LiOH, NaOH, NH3 · H2O) soluble in water, alkaline earth metal ions formed in the periodic table from top to bottom gradually soluble [Be (OH) 2, the alkali metal ions or alkali ions, Mg (OH) 2 is insoluble, Ca (OH) 2, Sr (OH) 2 is slightly soluble, and Ba (OH) 2, Ra (OH) 2 is easily soluble, and other bases are in addition to TlOH and Tl (OH) Is difficult to dissolve alkali and acid metathesis reaction is also known as neutralization reaction, that is, H + + OH- == H2O
