Why do metallic compounds conduct electricity as a solid? Why do nonmetals tend to form anions when they react to form compounds? Give two reasons why F_2 is the most reactive of the halogens. Why is fluorine highly reactive? Why does CrO3 in acidic water oxidize?
Does metallic bonding dissolve in water? What sulfates are soluble? Which one of the following compounds is soluble in water? (a) ZnCO3 (b) Ag3PO4 (c) CuS (d) Pb(NO3)2 What is solubility in physical chemistry? Are viroids one molecule?
Another suggestion is that the color might be related to ice with high levels of metallic compounds, including copper and iron. Recent expeditions have taken ice samples from green icebergs and ice cores—vertical, cylindrical ice samples reaching down to great depths—from the glacial ice shelves...
Would a substance that has a granular appearance, is not soluble, melts under a Bunsen flame, and does conduct as a solid or liquid have an ionic, covalent, or metallic bond?Homogeneous mixtures are also known as ___. a. solids b. compounds c. ...
BSA, a protein that dissolves in water and can hold many drugs, has been used to transport medicines at a nanoscale level. This system has several advantages, including breaking down naturally, being compatible with living organisms, having a simple manufacturing process, and producing consistent ...
to form disulfide bonds. However, this approach is restricted to drugs soluble in lipids and faces difficulties expanding its application. Furthermore, there are cases where the inclusion of reducing agents can lead to potential toxicity [86]....
31、ester.Insoluble in waterSuch as liquid hydrocarbons, ethers and halogenated hydrocarbons.(3) the water solubility of the solid (inorganic matter is abbreviated)The hydroxyl and carboxyl groups in the organic compounds are hydrophilic, and the alkyl group has hydrophobic properties. The larger the...
Vitamin D is a fat-soluble vitamin that is stored in the liver. Most of the vitamin D in our body is accumulated through exposure to sunlight. It is particularly known for its function in bones and teeth calcification, but today it is also studied and used for its contribution to the fun...
Ans: Alkali metals are highly reactive in nature, which is why they manifest themselves in combination with other elements, in nature. Most of these metals are easily soluble in water, which makes their extraction quite easy. All alkali metals show a silver-like lustre, which makes them appear...
Ionic compounds are made up of electrically charged particles, Why does not such a compound have an overall electric charge? The ions K^+ and Ca^2+ occur in chemical compounds, but the ions K^2+ and Ca^3+ do not. Explain. Explain why some ionic compounds are soluble in water. Why ...
