ABSTRACT: A d orbital is able to make a quadruple bond, which has four d electrons for each M-M center. Quadruple bonds are strong and short, and eventually decompose. In this experiment, molybdenum compounds with quadruple bonds are synthesized. Because of poor yields, the compounds were not able to be characterize to the full extend.
the heat calculated after a calimetry experiment is equal to the enthalpy change for reaction. Use the thermochemical data to calculate the enthalpy chanfe for the reaction of NaOH and CH3COOH.
