Calculate the equilibrium constant for the reaction below given that the concentrations of reacting species at equilibrium are (Cl2] = 0.11 M, [H2] = 0.15 M, and (HCl) = 0.95 M.
Cl2(g) + H2(g) → 2 HCl(g)

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.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
