... The standard entropy of a substance—its absolute entropy, S°—is the entropy value for the standard state of the species. The standard state is indicated with the superscript degree sign. For a pure substance, its standard state is 1 atm pressure. For a substance in solution, its standard state is a ...

Introduction to Nanoscience
... A nanodevice that often appears in science fiction is a nanocamera. This is used to view the inside of the body or in other confined spaces where an ordinary camera would not fit. Unfortunately, it is not possible to make such a camera using conventional far field optics. Light sources and light det ...

... We saw in previous lessons that some groups are electron donating (EDG) and some are electron withdrawing (EWG). The manner of substitution of electron-donating and electron-withdrawing groups in the reactants governs how easily the reactants produce a Diels-Alder product. When you give someone dir ...

... Three (or more) atom molecules cannot be explained by simple overlap of orbitals. Fact: a bond generally forms between two half-filled orbitals. Fact: an s-type orbital is spherical, so it could form a bond in any direction. Fact: the three p-type orbitals are at 90 degree angles to each other. ...

... Bond strength and length is also affected by the number of shared electrons. Sharing of one pair of electrons produces a single bond; whereas the sharing of two or three pairs of electrons produces double or triple bonds, respectively. Multiple bonds are stronger and shorter than single bonds. The p ...
