Consider the following mechanism for the oxidation of bromide ions by hydrogen peroxide in aqueous acid solution. h+ + h2o2 ? h3o2+ (rapid equilibrium) h3o2+ + br- ? hobr + h2o (slow) hobr+h+ +br- ? br2 +h2o(fast) which rate law is consistent with this mechanism? a. k[br-][h+]-1[h2o2]-1 b. k[h+][h2o2][br-] c. k[h+][h2o2] d. k[hobr][h+][br-]

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.
