(a) Interpretation: In the light bulb conductivity test, whether 0.1 M HF solution gives a dark, dim or bright light needs to be determined. Concept introduction: Strong electrolyte is defined as a solution which completely dissociates into ions. The resultant ions are good conductor of heat and electricity. The dissociation of a strong electrolyte is represented as follows: A B ( a q ) → A + ( a q ) + B − ( a q ) A weak electrolyte is defined as a solution which partially dissociates into ions. They are weak conductor of heat and electricity as compared to strong electrolytes. The dissociation of weak electrolyte is represented as follows: A B ( a q ) ⇌ A + ( a q ) + B − ( a q ) Non-electrolyte is defined as a solution which do not dissociate into ions. They do not conduct heat and electricity due to absence of ions in the solution. The dissociation reaction does not take place. A B ( a q ) → no reaction

Photochemical smog is formed in part by the action of light on nitrogen dioxide. The wavelength of radiation absorbed by NO2 in this reaction is 197 nm.(a) Draw the Lewis structure of NO2 and sketch its π molecular orbitals.(b) When 1.56 mJ of energy is absorbed by 3.0 L of air at 20 °C and 0.91 atm, all the NO2 molecules in this sample dissociate by the reaction shown. Assume that each absorbed photon leads to the dissociation (into NO and O) of one NO2 molecule. What is the proportion, in parts per million, of NO2 molecules in this sample? Assume that the sample behaves ideally.
