Product Description:

This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).

11. Packing

50kg or 100kg iron drum

 

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:What kinds of inorganic salts are required for plant growth
(N) Nutrition: Nitrogen is necessary for the growth and development of plants. Usually, the total amount of nitrogen in plants is not too high, such as 1.0-2.0% of the whole plant. The plant is a plant with high nitrogen content, and the nitrogen content in the plant leaves is about 3.5-5.0% of its dry weight.The nitrogen is mainly absorbed in the form of ammonium nitrogen and nitrate nitrogen, and some small molecules of organic nitrogen Such as urea can also be absorbed by plants.Now is the main component of protein, accounting for about 16-18% of the protein content in the cytoplasm and the nucleus are containing all the enzymes are also the main body of the protein.In addition, the nucleic acid, Phospholipids, chlorophyll, coenzyme and other compounds contain nitrogen
Q:Effects of Minerals on Plants
Minerals have a significant effect on plants, plants require about 25 elements, CHONPS Na Mg AL B MO Ca Fe Zn, etc. Most of these minerals have these elements, which are absorbed in the soil by roots and transported to plants Different parts, the role of a lot of plants lack of mineral leaves will be yellow, such as if there is no Mg, it can not be normal photosynthesis, because Mg is the necessary elements of synthetic chlorophyll, etc., if you want to know more profound, you can put each Kind of elements are checked.
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:The application of various inorganic salts in the human body?
Protein synthesis, nerve conduction, muscle contraction, body temperature regulation, complete cell maintenance and energy metabolism are inseparable from the magnesium.Many studies have confirmed that people lack of magnesium, often headache, irritability, emotional stress, limb weakness, depression insomnia, Children will grow and develop obstruction.Human blood levels of the body if the sudden decline, can lead to arrhythmia or coronary heart spasm, decreased immunity, women will appear dysmenorrhea.
Q:During the different periods of plant growth, the amount of water and inorganic salt required is different.
Plant life, although the need for a variety of inorganic salts, but different plants on the various types of inorganic salt requirements are different, such as cabbage, spinach and other human needs leaves of vegetables need nitrogen containing inorganic salts, tomato, peanuts need phosphorus Of the inorganic salt and more, sweet potatoes, potatoes need potassium-containing inorganic salts; the same plant with the growth period of the different requirements of inorganic salts are not the same, for example, plants in the seedling period requires nitrogenous inorganic salts , In the flowering, the results of the period of time need more phosphorus-containing inorganic salts. Therefore, different plants and the same plant growth period, the need for inorganic salts are different. So the answer is: different; different
Q:anybody here knows the difference of organic iron salt (ex. F.gluconate) vs inorganic (ex. F.sulfate)?
It it's organic, then the anion (the negative ion) is the conjugate base of an organic acid. If it's inorganic, then the original acid was inorganic (like H2SO4 making sulphates).
Q:would heterotrophic organism grow well in inorganic salt media? why or why not?
No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
Q:Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
Q:Now need to determine the freezing point of inorganic salt solution, what kind of freezing point instrument is more accurate?
With antifreeze.
Q:How does inorganic salts maintain osmotic pressure and pH
Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
