Eclipsed conformation (image right in Newman projection ) Staggered conformation In chemistry an eclipsed conformation is a conformation in which two substituents X and Y on adjacent atoms A, B are in closest proximity, implying that the torsion angle X–A–B–Y is 0°. [ 1 ]
Mould's YouTube video on rising self-siphoning beads, in which he demonstrated the phenomenon and proposed an explanation, [5] brought the problem to the attention of academics John Biggins and Mark Warner of Cambridge University, [6] who published their findings about what has now been called the "chain fountain" in Proceedings of the Royal ...
Under standard conditions, from CH 4 to C 4 H 10 alkanes are gaseous; from C 5 H 12 to C 17 H 36 they are liquids; and after C 18 H 38 they are solids. As the boiling point of alkanes is primarily determined by weight, it should not be a surprise that the boiling point has an almost linear relationship with the size ( molecular weight ) of the ...
The total solar eclipse phenomenon known as shadow bands—wiggly, rapidly moving bands of light and dark that can appear on flat, white surfaces about 30 seconds before and after totality—is ...
The Herschel wedge reflects about 4.6% of the light that passes through one of the prism faces that is flat to 1/10 of the wavelength of the light. The remaining ~95.4% of the light and heat goes into the prism and exits through the other face and out the back door of the housing; thus, the excess light and heat is disposed of and not used for ...
Hyperconjugation can be used to rationalize a variety of chemical phenomena, including the anomeric effect, the gauche effect, the rotational barrier of ethane, the beta-silicon effect, the vibrational frequency of exocyclic carbonyl groups, and the relative stability of substituted carbocations and substituted carbon centred radicals, and the thermodynamic Zaitsev's rule for alkene stability.
Polarized light can be produced by passing unpolarized light through a polarizer, which allows waves of only one polarization to pass through. The most common optical materials do not affect the polarization of light, but some materials—those that exhibit birefringence , dichroism , or optical activity —affect light differently depending on ...
Ben Taylor (Jan), Kiera Duffy (Bess) and Elizabeth Van Os (Mrs. McNeill) rehearse for Detroit Opera’s performances of Missy Mazzoli and Royce Vavrek's "Breaking the Waves" on April 6, 12 and 14.
