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:Are plants absorbing water and inorganic salts only through root tip or wrong?
Plants through the leaves can also absorb water and inorganic salts, but the root tip is the main part of the plant to absorb water and inorganic salts.
Q:Are fruits and vegetables inactive?
Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, including constant elements of iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8. Apple, pipa, durian, citrus, Watermelon, kumquat, peanuts, I know so much. Oh, there are: lotus lotus which contain inorganic salts
Q:Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
Drinking milk is more appropriate to do a proper practice, the milk is rich in calcium, phosphorus, iron, and zinc. There is a food that is eaten inside the sea, the sea of food is basically the content of inorganic salts are relatively high.
Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
, to maintain the osmotic pressure of cells, especially for the absorption of nutrients in plants have an important role.
Q:give me examples of organic, inorganic, acid, base, salt.?
Inorganic Bases
Q:Fitness body side, the body protein exceeded, inorganic salt normal, how can I do?
Strengthen exercise consumption.
Q:Cells are composed of water and inorganic salts or by organic matter and none
Cells are composed of water and inorganic salts or b
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological functions of carbohydrates (also known as carbohydrates): 1. Supply of heat. (Per gram of sugar can release 4 kcal of calories, is the main source of heat the body.) 2. constitute the body tissue. (All the nerve tissue, cells and body fluids are still carbohydrates.) 3. Can help the oxidation of fat to help the liver detoxification, promote growth and development.
Q:does the water solubility of an inorganic salt increase or decrease as the temp of the water is increased. Exp?
IIRC, it depends on the salt.
Q:In order to prove that magnesium is an essential salt for soybean life
Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.
