2.Write the balanced chemical equation for the decomposition of mercury(II) nitrate into mercury(II) oxide, nitrogen dioxide and oxygen gas.

-Write the Keq expression for the reaction.

-Calculate the Keq using the following concentrations: [mercury(II) nitrate] = 0.25M, [mercury(II) oxide] = 0.87M, [nitrogen dioxide] = 0.37M and [oxygen] = 0.42M.

-Circle the correct The reaction favored is the (forward, reverse)

some of the qualities most frequently associated with the baroque are grandeur, sensuous richness, drama, vitality, movement, tension, emotional exuberance, and a tendency to blur distinctions between the various arts.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
