Cautions during transportion:
The packing must be kept in good condition and the goods should be stored in a dry,cool and ventilated place.It should be separate from the cargo can burn and acid.It should avoid meeting water and moisture.It should give off the acetylene in iron drum before storing in warehouse. Rolling drums,heavy putting down and colliding are not allowed to avoid the spark leads to explosion.
- 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: Can inorganic salts be tested by LC / MS?
- LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.
- 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: What is the time when the maximum number of inorganic salts is needed
- The content of phosphorus in plants is lower than that of nitrogen and potassium, and is generally higher in seeds. Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis in plants , Respiration, energy storage and delivery, cell division, cell enlargement and other processes.
- Q: How to isolate the effects of inorganic salts on enzyme solubility
- Most enzymes are proteins, and high concentrations of inorganic salts can denature the protein and precipitate. The enzyme can be separated by this principle.
- Q: Why does inorganic salts affect chemical degradation of organic wastewater
- Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.
- Q: Indicating the organic compounds and inorganic salts in the boiling point, melting point and solubility of what is the difference
- Organic compounds are mainly covalently bonded, the mutual attraction between molecules is very weak, so its melting point, low boiling point, generally insoluble in water and soluble in organic solvents. Inorganic salts with ionic bonding, positive and negative ions electrostatic attraction is very strong, so the melting point, boiling point is very high, usually insoluble in organic solvents and soluble in water.
- Q: The inorganic salt is composed of?
- Inorganic salts are the general term for various inorganic salts. They are composed of inorganic acid radicals and metal cations or ammonium salts, mainly salts of organic acid salts, such as sodium chloride, potassium chloride and so on.
- Q: What are the nutritional requirements for bacterial growth?
- The nutritional conditions required for bacterial growth generally include water, carbon, nitrogen, inorganic and growth factors
- Q: Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.
- The water and inorganic salts in the soil are absorbed through the root of the root of the root of the root of the root of the root, due to root pressure by the body of the fiber duct system to the plant roots, stems, branches, leaves, flowers, fruit parts Of the cells in the supply of nutrients.
