Ethene (C2H4) can be halogenated by the following reaction:
C2H4(g)+X2(g)⇌C2H4X2(g)
where X2 can be Cl2 (green), Br2 (brown), or I2 (purple). Examine the three figures below representing equilibrium concentrations in this reaction at the same temperature for the three different halogens. Rank the equilibrium constants for these three reactions from largest to smallest.
Rank from largest to smallest. To rank items as equivalent, overlap them.

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.
