Q:Recently felt the whole body are sore, is not the relationship between the movement?

Need to exercise: a reasonable exercise can speed up the blood circulation, improve the rate of metabolism.

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: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:What is the acid anhydride?

An acid anhydride is defined as the removal of a molecule of water from an acid, and the remainder is called the acid anhydride of the acid. General inorganic acid is a molecule of the acid, the direct loss of a molecule of water to form the acid anhydride, the acid anhydride to determine the acid value of the same price. While the organic acid is two molecules of the acid or more

Q:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?

water and salt aren't foods. There is no caloric value in them, so they cannot be foods. We live on earth. All foods have an organic origin.

Q:What is salt oxide, what is not salt oxide?

Can not react with acid or alkali to produce the corresponding price of salt and water oxide is called non-salt oxide.

Q:What is the use of alkali?

Edible alkali has a small amount of fermentation, but its greatest role is to fermented the surface to the acid

Q:After running the training is best to drink what drinks add inorganic salt

C100 ah

Q:How does the edible base use?

(Sodium carbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is made from soda ash solution or crystal absorption of carbon dioxide after the finished product, both There is no difference between the system. Therefore, edible alkali in some places also known as baking soda (powder). Edible alkali is solid state, round, color white, soluble in water.

Q:What substances can detect inorganic salts

To see what inorganic salt, and mainly to test metal ions. Since it is sweat, then the main salt, that is, NaCl, which is detected NA + and CL-.
