If a reaction vessel initially contains an N2O4N2O4 concentration of 0.0550 MM at 500 KK , what are the equilibrium concentrations of N2O4N2O4 and NO2NO2 at 500 KK

answer: c.

explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
