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: What is the physiological function of inorganic calcium
- Cells and organisms of the important components
- Q: Is the conduction of excitement on neurons related to inorganic salts?
- Neurons are cells with long synapses (axons) that consist of cell bodies and cell processes. In the long axon with a layer of sheath, composed of nerve fibers, it is a small branch of the end called nerve endings. Cell bodies are located in the brain, spinal cord and ganglion, the cell processes can be extended to the body organs and tissues. The cell body is a nuclear part of the cell, its size is very different, about 4 to 120 microns in diameter. Nuclear large and round, located in the central cell, less chromatin, nucleolus obvious. There are plaque outside the cytoplasmic chromatin (formerly known as Neil body), there are many neuronal fibers.
- Q: Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
- Boron has a great influence on the reproductive process of plants, which can accelerate pollen differentiation and pollen tube elongation. In the absence of boron, pollen tube germination is affected, poor fertilization, which leads to the formation of seeds affected, the reduction of growth hormone produced by the reduction of growth hormone will affect the formation of fruit.
- Q: Which solvents have some solubility in inorganic salts
- A wide variety of dyes, dissolved complex. The original dyes are organic, but some salt, some metal complexes, some of the larger molecules of the fused ring compounds, some polymer heterocyclic compounds, in some common organic solvents in the solubility is better than disperse dyes Raw dyes and oil-soluble dyes (this is actually the raw material of solvent pigments, strictly speaking, not dyes). There are basically additives in the finished dyes, such as direct dyes, acid dyes, reactive dyes, cationic dyes and other water-soluble dyes will be added inorganic salts, disperse dyes, reducing dyes will be added sulfonate sodium dispersant. In addition, the dye and other chemical products, their purity requirements are generally very low, will allow the presence of certain insoluble impurities. So the organic solvent can not be completely dissolved dye products really is very common or even a normal phenomenon.
- Q: Cells in the water, inorganic salts, protein, lipid, carbohydrate and nucleic acid six words how wrong this sentence
- Wrong in the compound
- Q: ATP components are not inorganic salts
- Of course not pulling, because ATP is decomposed by glucose to get energy that is ATP and salt and water.
- 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: What is the risk of low inorganic salt?
- Iodine content in the human body is much lower than 1/10000 is a trace element. Function iodine in the human body to participate in the formation of thyroid. In the protein, fat, sugar metabolism promote bio-oxidation and coordination of oxidation of phosphoric acid process, adjust the energy conversion. Promote the metabolism of sugar and fat, regulate the water and salt metabolism in the organization, promote the absorption and utilization of vitamins, activate many important enzymes, promote growth and development. Lack of disease adult iodine deficiency can cause goiter ⑴ fetal and neonatal iodine deficiency can cause minor illnesses. Typical cases endemic goiter and local minor illnesses. Excessive symptoms iodine goiter, iodine thyrotoxicosis. Supply Adult 150ug Pregnant woman 175ug 206 Emulsifier 200ug. Food source 海 seafood seaweed, seaweed, fresh fish, clam dry, clam dry, scallops, mussels hai sea cucumber, jellyfish, lobster, etc.
- Q: Which minerals is richest source of Inorganic Salts ?
- Minerals are inorganic salts - eg.potassium nitrate - absorbed by plants from soil - a good source of inorganic nitrogen and potassium.
- Q: I need help with this
- anything which contain carbon is organic. so enzyme is the odd one out.
