Nanotechnology has become an important field, with applications ranging from high-density data storage to the design of “nano machines.” One common building block of nanostructured architectures is manganese oxide nanoparticles. The particles can be formed from manganese oxalate nanorods, the formation of which can be described as follows: Mn 2+ ( a q ) + C 2 O 4 2 − ( a q ) ⇌ M n C 2 O 4 ( a q ) K 1 = 7.9 × 10 3 MnC 2 O 4 ( a q ) + C 2 O 4 2 − ( a q ) ⇌ M n ( C 2 O 4 ) 2 2 − ( a q ) K 2 = 7.9 × 10 1 Calculate the value for the overall formation constant for Mn(C 2 O 4 ) 2 2− : K = [ Mn(C 2 O 4 ) 2 2- ] [ Mn 2+ ][C 2 O 4 2- ] 2

Complete the reaction in the drawing area below by adding the major products to the right-hand side.
If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area
instead.
Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge
bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center.
