The formation of FeSCN2+ in an aqueous solution is represented by the chemical equilibrium shown below. A light red-brown solution is prepared combining 12.50mL of Fe(NO3)3.0.5mL of 0.002M KSCN and 37.OmL of water that had been slightly acidified. If an additional of 0.5M Fe (NO3)3 is added, which of the following predicts and explains correctly whether the darkness of the color of the solution will change?

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.
