C)The brown gas NO2and the colorless gas N2O4exists in equilibrium; N2O4 (g)
NO2 (g)
0.625mol of N2O4was introduced into a 5.00L vessel and was allowed to
decompose until it reached equilibrium with NO2. The concentration of
N2O4at equilibrium was 0.075M. Calculate Kc for the reaction

Need ! asap will mark 10 pts using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers

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.
