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 come a penny can hold more drops of the salt water solution than just plain tap water from your faucet?: Surface Tension Of Salt Water

Q:Milk food rich in nutrition, in addition to containing a variety of inorganic salts which also contain three types of organic energy can be organic: Fat Glucose Protein

Q:What are the main physiological functions of inorganic salts?: to maintain the organization's normal excitability

Q:Sodium bicarbonate is not an inorganic salt: Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt

Q:Like the role of B, Fe, Mg, Ca, Mn, Cu, Cl, P, S, N ...., the more specific the better (college entrance examination range): Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable.

Q:The application of various inorganic salts in the human body?: Iron is an essential trace element in the animal body and plays an extremely important role in the metabolism of animals.It is not only a component of a variety of compounds but also a variety of metabolic-related enzyme activities, and to a certain extent The immune function of the body.

Q:is table salt organic or inorganic, why?: if its found in nature its organic if its made by man its synthetic. table salt is found in the ocean so i guess it would be organic.

Q:A. oxygen demanding wastesB. organic plant nutrientsC. inorganic plant nutrientsD. water soluble inorganic chemicalsE. sediment: Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment

Q:Would the amount of saltwater drops a penny surface could hold without spilling increase, or decrease, as the salt concentration increases? Also, maybe an explanation behind why it increases/decreases?Thank you!: The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.

Q:Can you please help me with this question and give me a website reference.: Many of these materials enter the water through natural channels---minerals, salts and the like come from exposure to rocks, dirt and other inorganic materials.
