Automatic 'balancing' of Chemical Equations
A computer program conceived as an aid to chemistry students is presented for the calculation of the stoichiometric coefficients of chemical equations~ Once these coefficients are calculated, the entire corresponding chemical equation with the respective coefficients is shown on the screen. The program is run from an “Options Menu”, so the user does not have to learn commands. To compute the st...
متن کاملSome Matrix Iterations for Computing Generalized Inverses and Balancing Chemical Equations
An application of iterative methods for computing the Moore–Penrose inverse in balancing chemical equations is considered. With the aim to illustrate proposed algorithms, an improved high order hyper-power matrix iterative method for computing generalized inverses is introduced and applied. The improvements of the hyper-power iterative scheme are based on its proper factorization, as well as on...
متن کاملA Cognitive Modeling Tutor Supporting Student Inquiry for Balancing Chemical Equations
Improved interactive tutoring capabilities in educational software for chemistry problem solving is an important need that has been clearly articulated by teachers and students. The purpose of this work is to examine the incorporation of new concepts from the field of artificial intelligence (AI) as a route to meaningful individualized tutoring. The basic shift is to replace specific foreknowle...
متن کاملConservation Equations for Chemical Elements in Fluids with Chemical Reactions
It is well known that when chemical reactions occur, the masses of the participating molecules are not conserved, whereas the masses of the nuclei of the chemical elements constituting these same molecules, are conserved. Within the context of non-equilibrium thermodynamics, the first fact is expressed by the differential balance equations, for the densities of the chemically reacting molecules...
متن کاملComplex and detailed balancing of chemical reaction networks revisited
The characterization of the notions of complex and detailed balancing for mass action kinetics chemical reaction networks is revisited from the perspective of algebraic graph theory, in particular Kirchhoff’s Matrix Tree theorem for directed weighted graphs. This yields an elucidation of previously obtained results, in particular with respect to the Wegscheider conditions, and a new necessary a...
