Resonance structures are used when a single Lewis structure cannot fully describe the bonding; the combination of possible resonance structures is defined as a resonance hybrid, which represents the overall delocalization of electrons within the molecule. In general, molecules with multiple resonance structures will be more stable than one with ...If NO 2 were linear, it would not be polar any more than carbon dioxide is a polar molecule; for more, see this answer. The way we would know, from the Lewis structure, that NO 2 is bent is the fact that the nitrogen atom has three "groups" around it: two oxygen atoms and the unpaired electron. Atoms with three groups adopt a trigonal-planar ...
No symmetry must be used in the final calculation, thus, use a Symmetry NOSYM keyword if your molecule is symmetric. The analysis is not completely implemented for meta-GGA’s and meta-hybrids. Improvements in ADF2012 to both the ETS and NOCV analysis with hybrids.

NO concentrations of 50 - 300 ppm C2H2/air (Φ = 0.8 - 1.6) flames on a Hencken burner. NO measurements in highly sooting flames H2/air non-premixed flame within counter-flow burner. Measured NO profiles are in very good agreement with calculated profiles - a surprising result given the drastic variation in collisional rates throughout the ... Ethyne is C2H2 so I balanced the combustion equation to be . After, I set up the standard enthalpy of formations of each of the products and reactants and got: -2145.7 kJ - 2 mols C2H2 = -1300 kJ. After solving for C2H2, the answer I got was -422.85 kJ/mol. Can someone tell me where I went wrong?
In molecules containing double bond, which has a pi bond, there is no free rotation and such molecules exist in isomeric forms of 'cis' and 'trans'. In the 'cis' form the similar atoms lie on the same side of a plane placed along the internuclear axis while in the 'trans' form the similar atoms lie on the opposite sides.
