Which of the following best describes the molecular orbital theory of bonding? choose one: a. a theory of bonding based on the mixing of atomic orbitals of similar shapes and energies to form molecular orbitals that extend to two or more atoms b. a theory where the bonds and lone pairs of valence electrons in a molecule are represented in two-dimensions c. a theory that predicts the arrangement of valence electron pairs around a central atom minimizing their mutual repulsion to produce the lowest-energy orientations d. a theory of bonding that describes bonds as the electrostatic attraction between species of opposite charge e. a theory of bonding that assumes covalent bonds form when half-filled orbitals on different atoms overlap or occupy the same region in space

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
