The equilibrium constant, Kc, for the following reaction is 10.5 at 350 K. 2CH2Cl2(g) CH4(g) + CCl4(g)

Calculate the equilibrium concentrations of reactant and products when 0.277 moles of CH2Cl2 are introduced into a 1.00 L vessel at 350 K

please answer and explain

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
