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:How to isolate the effects of inorganic salts on enzyme solubility
The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.
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:What is the inorganic salt
The main sources of various inorganic salts and the lack of the main performance (1) sodium sodium is the main ingredient of salt.China's nutrition society recommended adults over 18 years of age sodium intake of 2.2 grams per day, the elderly should take light food Sodium is commonly found in a variety of foods. The main sources of sodium are sodium, soy sauce, pickled foods, smoked foods, salty foods, etc. (2 Calcium is an important part of bone. Disease, osteoporosis, etc .. China Nutrition Society recommended adults aged 18-50 adult calcium intake of 800 mg per day; 50 years of age in the elderly 1000 mg.General calcium-rich foods are milk, yogurt, Oatmeal, sea cucumber, shrimp, wheat, soybean meal, soy products, lily, etc. (3) magnesium is the necessary elements to maintain the structure and function of bone cells.Magnesium deficiency can lead to nervous tension, emotional instability, muscle tremor and so on. (4) Phosphorus is an important part of the composition of bones and teeth. (4) Phosphorus is an important component of bone and teeth. (4) Phosphorus is an important component of bone and teeth. Severe phosphorus deficiency can lead to anorexia, anemia, etc. China Nutrition Society recommended adults over 18 years of age the appropriate intake of phosphorus is 700 mg. Common phosphorus-containing foods are lean meat, eggs, milk, animal offal, kelp, Nuts, coarse grains. (5) Iron is the most content of trace elements in the human body, iron and the human body's life and its health are closely related to iron deficiency will lead to iron deficiency anemia, immunity decreased. China Nutrition Society recommended 50 years old More than men's or women's iron daily intake of 715 mg. Common iron-rich foods are animal liver, kidney, caviar, lean meat, potatoes, wheat bran.
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:Why is sodium chloride(salt) an inorganic compound?
This is because NaCl does not contain Carbon. It is usually compounds that contain Carbon which can be considered ORGANIC compounds. :)
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 are the differences between inorganic salts and salt?
Is an inorganic salt of inorganic salts by metal cations and non-metallic anions or ammonium ions and non-metallic anion compounds. Sodium chloride is a kind of inorganic salts!
Q:What foods contain inorganic salts?
Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice
Q:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolyte?
Which "inorganic salts" are you talking about? There are hundreds!
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).
