Appearance: white powder, 325-3000 mesh

Application: It can be used as the raw materials or fillers in oil paint,ink,plastic,rubber and battery ,the Surface smear medicament of the Printing paper and copper board , and sizing agent for textile industry. As clarifying agent,it can play a role of anti-foaming and increase the glossy of glass products. It also can be used as an anti-radiation protective wall materials. In addition,it’s widely used in pottery , enamel, spices and paints, etc. What’s more, it can be used as the raw materials to produce other barium salts.

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:Chemical formula The longest inorganic salt: Is this meaningful?

Q:Organic chemistry extraction lab. If the KBr wasn&#39;t there I would just add HCl to protonate the NH2, but I&#39;m not sure if that will affect the KBr or the carbon chain. Both of these are in an aqueous phase.: The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.

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: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:What is the use of inorganic salts and organic salts?: The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.

Q:In order to prove that magnesium is an essential salt for soybean life, two soybean seedlings with the same growth status are taken, one of them is cultured in magnesium-containing culture medium and the other is cultured in (). A. Pure water B. Sand without sand. Water containing only magnesium. Media containing no magnesium: Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.

Q:Is it possible to adjust the internal temperature of the carbohydrate in the vacuole: multi-cell plant cells are living in the individual within the water environment, but this environment with the human body's internal environment can only be similar is not the same, and plant cells and no extracellular liquid this argument.

Q:As if there are two kinds of nitrogen, phosphorus and potassium, hoping to get answers and explain their respective roles: (N) Nutrition: Nitrogen is necessary for the growth and development of plants. Usually, the total amount of nitrogen in plants is not too high, such as 1.0-2.0% of the whole plant. The plant is a plant with high nitrogen content, and the nitrogen content in the plant leaves is about 3.5-5.0% of its dry weight.The nitrogen is mainly absorbed in the form of ammonium nitrogen and nitrate nitrogen, and some small molecules of organic nitrogen Such as urea can also be absorbed by plants.Now is the main component of protein, accounting for about 16-18% of the protein content in the cytoplasm and the nucleus are containing all the enzymes are also the main body of the protein.In addition, the nucleic acid, Phospholipids, chlorophyll, coenzyme and other compounds contain nitrogen

Q:I need help with this: The correct answer is enzymes. Enzymes are composed of carbon, nitrogen, oxygen and traces of other elements such as sulfur, but are produced in nature only by living things.
