Chapter 12, Problem 12.8A
Interpretation Introduction

(a)

Interpretation:

The picture of bands for each metal Hf, Pt, and Re should be determined.

Concept introduction:

The band theory is used to explain hardness, electrical conductivity, melting point for different metals. It can be explained as a theory related to set of MOs that have very less energy difference between them. These sets of MOs are also known as bands. Melting point of any metal depends on occupancy of both MOs, bonding and antibonding. When the electron from bonding MO can be excessed easily relative to antibonding MO electrons, then melting point metal is higher.

Interpretation Introduction

(b)

Interpretation:

The hardest metal should be determined and also, metal with highest melting point among Hf, Pt, and Re should be determined.

Draw product A, indicating what type of reaction occurs. NH2 F3C CF3 NH OMe NH2-NH2, ACOH A
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.
Correct each molecule in the drawing area below so that it has the skeletal ("line") structure it would have if it were dissolved in a 0.1 M aqueous solution of HCI. If there are no changes to be made, check the No changes box under the drawing area. No changes. HO Explanation Check NH, 2 W O :□ G ©2025 M unter Accessibility
