5.FAQ

1)How many tons does your factory can supply each moth?

30000tons/month

2)How to quarantee the quality of the products?

you can arrange SGS&BV or other quality inspection.

3) why you buy from me?

We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.

Q:Please help i need the answer for a classwork assignment due today. I&#39;ve looked everywhere online but i cant find the answer.: the web page (below) discusses: Basal Salt Mixtures The use of balanced salt solution (BSS) in cell and tissue culture is generally attributed to early workers in the field. In 1885, Sydney Ringer developed a solution of inorganic salts designed to maintain contractility of mammalian heart tissue. A less specific salt solution was designed by Tyrode for use in work with primary mammalian cells. Tyrode's salt solution became the accepted fluid for diluting protein components of media of natural origin. Since that time, many other balanced salt solutions have been developed for use in cell and tissue culture. The current role of balanced salt solution in cell culture is multi-faceted and can be divided into four principle functions. see web page for extensive discussion on the good things about it

Q:how come a penny can hold more drops of the salt water solution than just plain tap water from your faucet?: Surface film tension is the property of a liquid by which it acts as if its surface is a stretched elastic membrane. This tension allows insects to stand on the water’s surface. Surface film tension is caused by the attraction of water molecules to each other; in addition, the surface molecules are attracted to the underlying molecules. The amount of surface film tension is affected by both temperature and dissolved substances. An increase in temperature lowers the net force of attraction among molecules and so decreases the surface tension. An increase in dissolved organic substances also lowers the surface tension However, an increase in dissolved inorganic salts causes a rise in surface tension - increases the attraction of the surface molecules for the underlying molecules.

Q:Sodiumcorbonate is inorganic salt , why it is not organic substance even it contains carbon?: Organic molecules have carbon to carbon bonds. EDIT: I wonder why I got a thumb down for stating the definition of an organic molecule? Yahoo answers is a weird place. If there's only one carbon atom in a molecule its not an organic molecule, because there can be no C-C bonds...

Q:Inorganic salt function: 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:What is the physiological function of inorganic calcium: Maintain the life of cells and organisms

Q:and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^): Any carbon-containing compound is considered organic with the exception of carbonates, bicarbonates, carbon dioxide and carbon monoxide.

Q:in the ocean: Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.

Q:My body fat rate 14.6 normal body fat percentage 31.2 is more than the normal value I do not know the difference between the two please God answer ah Thank you very grateful and then those elements of my lack of God is the situation ah I love meat is not a vegetarian! And I super love to eat eggs! And my super love to drink water!: I am also a little lower inorganic salt so point, the coach said that usually drink some salt. Protein and water are low can only explain a problem, have a good fat under the conversion.

Q:I am told to find which bottled mineral water brands contain the most mineral salts.But im not sure if the mineral salt here is talking about the common table salt (Sodium Chloride) or the chemical salt (ionic compounds such as sulfate and chloride) or the whole list of dietary minerals (potassium, chlorine, calcium, magnesium, ect.) I normally think it is just the table salt but im afraid I might get wrong. So what is the exact definition?: it okorder /C005969/mi... "Mineral salts are inorganic (carbon-free) elements that turn to ash when burned. "
