Explain the phenomenon of mutarotation with reference to carbohydrates. By what means is it detected? Ammonia, H2N-H, has pKa=36 and acetone has pKa=19. Will the given reaction take place? Explain. What generalizations can be made about silver halides? Show how...
Explain why alcohols have higher boiling points as compared to their corresponding alkanes. Use appropriate chemical equations to explain this phenomenon. Explain why the chemical formula HCl can represent two different chemical systems. Explain why water is such a good solvent for so ...
节约用水是中华民族的传统美德 Everybody good.Russia is Li Hua, comes the proud 21 classes.The water is a fountainhead which we live, our life does not leave the boiling water.Therefore we should save the water used.But present very many schoolmates waste the water the phenomenon to be very...
In this activity, students are asked to use their understanding of noncovalent interactions to explain (a) why the boiling point differs for two pure substances (chemistry phenomenon) and (b) why temperature and base pair composition affects the stability of DNA (biological phenomenon). The ...
Shine some light on nematic liquid crystals and some of it will reflect back again in a type of reflection known as iridescence—the same phenomenon that makes colors from the scales on a butterfly's wing, the grooves on an old-fashioned LP record, or the surface of a soap bubble....
Section 4 frames the phenomenon through the analysis of the previous academic studies. Then, a framework based on the literature review was developed to define sustainable best practices and KPIs for the soft drink sector. The aforementioned framework was evaluated through two case studies. The ...
Boiling Point: Boiling point can be defined as the temperature at which a liquid starts turning into gas. The boiling point is dependent on the nature and strength of the intermolecular forces that hold the molecules of the substance together. ...
Melting points represent the point at which the substances present in solid form change to the liquid form when the temperature is raised. It involves the bond breakage in the solid form of substances. It is measured experimentally by the use of a liquid with a high boiling point, thermometer...
The rock cycle refers to the process by which the soils and the rocks of the Earth are constantly being transformed, by the action of several agents like pressure and temperature. The three types of rocks, namely, sedimentary, igneous, and metamorphic, are continuously being exposed to these ...
Explain your reasoning.Boiling Point:Boiling point is the temperature at which the vapor pressure equals the atmospheric pressure. At this temperature, the liquid starts changing into gas. The boiling point is dependent on the size of the molecule and the intermolecular forces present....
