At a certain temperature K = 1300 L/mol for the reaction given above. Calculate the concentration of FeSCN2+ at equilibrium if 0.077 mol of Fe(NO3)3 is added to 1.00 L of 0.24 M KSCN. (Neglect any volume change.)

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
