(02.05 MC) The complete orbital notation diagram of an atom is shown.

Based on the diagram, what values can be assigned to the principal quantum number for the electrons in the atom? What information does this quantum number
provide about the location of the electron?

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Consider the reaction: n2(g) + o2(g) ⇄ 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
