“Mole Concept” is an interactive app for students to learn mole concept, mole calculations, mole chemistry, mole concept formulas, mole concept numericals in an easy and engrossing way by visualizing the colorful images. It is one of the best educational applications which is designed to help...
TURBOMOLE is a Quantum Chemistry program package and one of the fastest and most stable codes available for quantum chemical simulations (DFT, MP2).
Especially, results can be often incorrect in stoichiometry problems since the calculations revolve around the mole concept. The purpose of this study was to determine the effectiveness of using conceptual change strategy in teaching the mole concept to freshman general chemistry students. A pretest-...
Electronic structures of ionically functionalized polyacetylene analogues, PA and PC, are surveyed by both oligomer investigations (using density functional theory with the aid of an effective linear scaling strategy) and polymer calculations (with the periodic boundary condition). The solvent effects on...
