Complete the mechanism for the following mixed claisen condensation, where ethyl 2-phenylacetate is added dropwise to a solution of ethyl formate in ethoxide anion, by adding missing atoms, bonds, charges, nonbonding electrons, and curved arrows. note the resonance arrow between panels two and three.

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
