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%).

10. SIZE


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:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
Q:How too much to eat too much inorganic salt
Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.
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)?
water and salt aren't foods. There is no caloric value in them, so they cannot be foods. We live on earth. All foods have an organic origin.
Q:Which crop feet can provide C N inorganic salts for fungal growth
Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
Q:Common inorganic salt ions will appear when the corresponding symptoms
Iodine: goiter, mental and physical development disorders
Q:what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
The organic part is cells that produce bone matrix (inorganic) with excess calcium and phosphorus, and break down the bone salts when the calcium is needed elsewhere in the body. The inorganic matrix provides protection, support and structure for the body. And, actually, red bone marrow is the place where formed elements of the blood are manufactured. Dude, this is not exactly botany. :-P
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 to eat can promote the absorption of inorganic salts
Transpiration on the absorption of inorganic salts has little effect, the book or which exercises on the image shows the problem
Q:What is the relationship between electronegativity and the solubility of a inorganic salts?
The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.
