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: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
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.

Q:Where are the parts of the bryophyte absorb water and inorganic salts?
Moss moss moss, moss Gang, moss root through the fake root absorption, that is, the use of cell penetration technology, moss Gang has evolved out of the root, so you can directly through the relatively low roots to absorb Oh
Q:How does inorganic salts maintain osmotic pressure and pH
PH ~ inorganic salts of carbonates bicarbonate, hydrogen phosphate / dihydrogen phosphate, can help regulate the pH value of the internal environment, even if the external environment Zoumu changes, the environment will not change too fast, there will be a Buffer room
Q:what percent of dissolved salts found in seawater are minor inorganic salts, or trace?
Seawater varies in composition a little but generally is about 3.5% salts. Of this about 3.1% is sodium chloride. So the remaining 0.4% is the other salts (Magnesium, Calcium and Potassium mostly, followed by just about every natural element in the periodic table in trace amounts)
Q:What is the role of alkaline powder
Alkaline powder can treat burns. If the scald area pony immediately coated with alkaline powder, and then drop a few drops of water, alkali powder will be dissolved immediately after the water. Was burned parts of the beginning of the alkaline powder coated with a sense of burning, and after a while feel very comfortable ice, like the heat burned alkaline powder is like, so repeated several times can reduce the pain and trauma burns. If the area of burns larger, can be soaked with alkali powder soak for about half an hour or an hour.
Q:What is the big base?
Large alkali is the main component of sodium carbonate.
Q:How can we order sour?
Arm more exercise.
Q:What fruit contains more minerals?
Watermelon fruit contains 90% or so, so there are "watermelon," said watermelon contains a variety of nutrients and chemical substances. Watermelon pulp contains protein, sugar, crude fiber, potassium, phosphorus, calcium, iron, sodium, magnesium Chlorine, niacin, vitamin A, vitamin B1 and vitamin B2 in the watermelon juice also contains citrulline, alanine and glutamic acid and other amino acids, malic acid and other organic acids, pectin and a small amount of glycosides, and Medlar, cinnamon and other alkaloids and so on.
