g A 100.0 mL100.0 mL solution of 0.0200 M Fe3 0.0200 M Fe3 in 1 M HClO41 M HClO4 is titrated with 0.100 M Cu 0.100 M Cu , resulting in the formation of Fe2 Fe2 and Cu2 Cu2 . A PtPt indicator electrode and a saturated Ag||AgClAg|AgCl electrode are used to monitor the titration. Write the balanced titration reaction.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
