B) Eight times the number of H+ ions that are consumed

C) one-fifth the number of Fe3+ ions that are produced.

D) one-third the number of H2O molecules that are produced.

In what environment would mineral formation caused by high pressures and high temperatures most likely occur?

Light waves travel than sound waves.

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.
