Q:Whether the metal oxides are alkaline oxides

CrO3, Mn2O7 are metal oxides, they are acidic oxides

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:The effect of inorganic salt medium and the difference with enrichment medium

The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.

Q:I need help with this

anything which contain carbon is organic. so enzyme is the odd one out.

Q:Alkaline pool can breed what

In the future of adult fish sales process found that after long-distance transport, part of the fish surface congestion, affecting the survival rate of transport and marketing. This may be associated with the addition of fish oil in the larger amount, resulting in high fish fat, muscle softness. Suggested in the late breeding, should reduce or even stop the addition of fish oil, and should increase the water flow, stimulate the fish, to achieve the purpose of exercise to improve the survival rate of transport.

Q:Can an atom be an element?

Yes, the inert element is a single atom molecule, the metal element is also a single atom but generally can not be called a molecule (reason

Q:Why do you go to sleep

If occasionally, may be caused by sleeping position, if often, it may be caused by lumbar muscle strain. With the usual lack of physical exercise, often Jiuzha long station, often bending activities, heavy physical labor, feelings of cold and so on.

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-.

Q:The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is

wrong. Can only promote the transport up! Can not promote absorption.

Q:General identification method of inorganic salts

Take the test solution, add thiocyanate solution solution, that is blood red. Fe3 + + NH4SCN → Fe (SCN) 2 + (blood red) Take the test solution, plus potassium ferrocyanide test solution, that is, white precipitate, separation, precipitation in dilute hydrochloric acid insoluble. 3Zn2 ++ 2K4 [Fe (CN) 6] → K2Zn [Fe (CN) 6] 2 ↓ (white) + 6K +
