i need help i cnt figure this out and the / means divide Block a: 65.14kg before: 100L after: 103.38L 100L - 103.38L = /65.14kg Block B: 0.64kg before: 100L after:101L 100L - 101L = /0.64kg Block c: 4.08kg before: 100L after: 105.83L 100L – 105.83L = /4.08kg Block D: 3.10kg before: 100L after: 103.38L 100L – 103.38L= /3.10kg Block E: 3.53kg before: 100L after: 101L 100L – 101L = /3.53kg

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.
