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: Inorganic salt of the inorganic salt function: Although inorganic salts in the cell content is relatively small, but there are many important role. 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. The various inorganic salts dissolved in the cells have a certain total concentration, such as human body fluid concentration of 0.9%, frogs of 0.65%, which for maintaining cell osmotic pressure, so that cells maintain a certain shape has an important role, too high or Too low will lead to cell due to water or dehydration to change the cell morphology. There are also a number of buffering systems in the body, which are a group which has a neutralizing effect on the added acid or base so that the pH does not change significantly and therefore plays an important role in maintaining the acid-base balance of the cells.

Q: Is it possible to adjust the internal temperature of the carbohydrate in the vacuole: the internal environment refers to the human cell life of the liquid environment, that is, extracellular fluid.

Q: During the different periods of plant growth, the amount of water and inorganic salt required is different.: Plant life, although the need for a variety of inorganic salts, but different plants on the various types of inorganic salt requirements are different, such as cabbage, spinach and other human needs leaves of vegetables need nitrogen containing inorganic salts, tomato, peanuts need phosphorus Of the inorganic salt and more, sweet potatoes, potatoes need potassium-containing inorganic salts; the same plant with the growth period of the different requirements of inorganic salts are not the same, for example, plants in the seedling period requires nitrogenous inorganic salts , In the flowering, the results of the period of time need more phosphorus-containing inorganic salts. Therefore, different plants and the same plant growth period, the need for inorganic salts are different. So the answer is: different; different

Q: What is the inorganic salt, is not the organic salt and is not the inorganic salt: Inorganic salt: Acid-base reaction product without carbon element However, the chemical properties such as carbonates and carbon oxides are the same as those of inorganic substances. Therefore, they are also classified as inorganic substances

Q: salt is organic or inorganic?: If you mean table salt, NaCl then it's inorganic. No Carbons there.

Q: List the major electrolytes released by inorganic salts when placed in water and explain how these electrolytes are needed for metabolic reactions.: Which "inorganic salts" are you talking about? There are hundreds!

Q: What are organic and inorganic salts?: An organic salt is a salt containing an organic ion ( carbon atoms ) The reaction product of an organic acid and an inorganic base, for example, sodium acetate (CH3COONa) from the reaction of acetic acid (CH3COOH) and sodium hydroxide (NaOH). The Organic ion, here, is CH3COO- Inorganic compounds come principally from mineral sources of non-biological origin. The modern definition of inorganic compounds often includes all metal-containing compounds, even those found in living systems. So, Inorganic salts are salts of such elements (salts that don't contain carbon atoms) For eg: NaCl, KCl, BaCl2, Al2SO4, etc

Q: How to extract inorganic salts in soil?: Dissolve, filter, evaporate

Q: What are the nutritional requirements for bacterial growth?: For inorganic salts: bacteria need a variety of inorganic salts to provide a variety of elements of bacterial growth, which requires the concentration of 10.3 ~ 10.4mol / L elements for the common elements, the need for concentration in the
