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: 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: What are the disadvantages of inorganic salt deficiency and too much: The role of inorganic salts in plant life Plants require the most inorganic salts to be nitrogen-containing, phosphorus-containing and potassium-containing inorganic salts. These three types of inorganic salts have different effects in plant life. Lack of performance nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown. P: Promote the development of seedlings and the opening of flowers so that the fruit and seed are mature early. Lack of performance: the plant is particularly short, leaves were green, and purple. Potassium: Stable stem to promote starch formation. Lack of performance: stems weak, easy to lodging, leaves the edge and the tip was brown, and gradually dry. In addition to these three types of inorganic salts, plants also require many types of inorganic salts. Among them, the demand for some inorganic salts is very small, but they are in the life of the plant also plays a very important role. For example, the lack of iron-containing inorganic salts, fruit trees will be yellow leaf disease; lack of boron-containing inorganic salts, rape will be "spent" (only flowering fruit)

Q: What cells produce the collagen and inorganic salts of bone matrix?: The collagen is produced by chondrocytes. The minerals that make up the bone are precipitated by osteoblasts.

Q: What is the inorganic salt, is not the organic salt and is not the inorganic salt: In fact, Na2CO3 is also inorganic salt ah! The Can not according to whether there is C to divide!

Q: An inorganic salt is dissolved in water and yields a solution that has a color. Make a statement about the type of element the substance contains that casuses the color.Thanks!: Many inorganic salts form colored solutions . pper ( II) sulfate ( Blue ) nickel (II) acetate = green, mangaanse ( II) chloride = pink, iron(III) chloride = yellow, potassium dichromate, orange and so many more Can you be more specific ?

Q: what is the function of salts in DNA extraction?: DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.

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: as a example potesium,sodium,magnees,calcium: The sodium-potassium pump is most important in controlling the working of neurotransmitters. Calcium ion is also generated in voltage gated Ca++ channel, and Magnesium is necessary for metabolic functions. But Sodium is one of the most important inorganic component in our body. Of course Potassium is also as important. But, if you have ever seen the back of all food products there is a special part showing amount of Sodium in it...even Snacks.. :)

Q: The difference between the ignition of inorganic salts and organic matter: Will the ignition of inorganic matter and the ignition of organic matter, thank you
