Q: What inorganic salts and trace elements are there in rice?: Ribulose (0.08 mg) Nucleic Acid (1.50 mg) Vitamin C (8.00 mg) Vitamin E (1.01 mg) Calcium (11.00 mg) Phosphorus (121.00 mg) Potassium (97.00 mg)

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 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: Divided into organic compounds and inorganic compounds are not two categories

Q: citrate, What is the rationale for using a medium with this type of composition for the performance of the citrate utilization test?Thank you!: Simmons Citrate Medium

Q: What is the disease of inorganic salt crystals?: Drink less, the urine will be reduced, the urine of the inorganic salt concentration will be high, the discharge of urine encountered outside the cold air, will immediately cool, urine inorganic salts to precipitate down, so that urine Into the lime watery white turbid liquid. Check this urine, the urine heated to a certain temperature will make it clear; also due to temporary urine alkalization caused by white turbid urine, such as taking alkaline drugs or After a lot of alkaline food, or eat can make the inorganic salt in the urine of the increase in the content of food, fruit, vegetables, there will be white urine.

Q: Why are inorganic sodium salts much better soluble in ethanol than potassium salts?: Sodium ions are smaller cations than potassium ions. Ethanol has a polar bond in the OH, but it also has a nonpolar tail, the ethyl group. So, unlike water, that has two OH groups that are polar and can interact with cations, ethanol has only one, so it requires strong electrostatic attractions to form a hydrogen bond - dipole interaction with any cation that it encounters. Being smaller, the sodium ions have their positive charge concentrated over a much smaller volume, so the polar OH bond in ethanol is more strongly attracted to the concentrated charge of the sodium than to the diffuse charge of the potassium ion, making the salt more soluble in this solvent.

Q: would heterotrophic organism grow well in inorganic salt media? why or why not?: No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.

Q: Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?: Soy products containing more calcium. Animal liver, spinach iron, zinc and so on.
