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:Chemistry help! physical and chemical properties of salt and sugar!?
I believe it's Physical, most of the times such changes are physical, melting point, sublimation, evaporation, etc.
Q:A colorless solution contains which inorganic salt?
Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.
Q:What is the composition of inorganic salts?
Most of the inorganic salts in the cell are present in the form of ions
Q:Nutritional characteristics of carbohydrates and inorganic salts in vegetables
Carbohydrates include sugars, starches, cellulose and pectin substances. Its species and quantity, because of the types of food and varieties are very different.
Q:What inorganic salts and trace elements are there in rice?
Pantothenic acid (0.60 mg) Carbohydrate (76.80 grams) Folic acid (3.80 micrograms) Dietary fiber (0.60 grams) Biotin (220.00 micrograms) Thiamine (0.33 mg)
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: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:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
When the boron deficiency occurs, pollen tube germination is affected and poor fertilization leads to seed formation.
Q:is table salt organic or inorganic, why?
Inorganic - NaCl - no complex carbon compounds.
Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
(2) to participate in and maintain the metabolic activity of the organism.
