Asample of h gas (2.0 l) at 3.5 atm was combined with 1.5 l of n gas at 2.6 atm pressure at a constant temperature of 25c into a 7.0 l flask. the total pressure in the flask is atm. assume the initial pressure in the flask was 0.00 atm.

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.
