The electrical conductance of copper metal decreases with temperature, but that of a CuSO 4 solution increases with temperature has to be explained. Concept introduction: Electrical conductivity of metals: Electrical conductivity of metal is nothing but the moment of electrically charged particles or electrons. In metals, the atoms are characterized in the presence of valence electrons. The mobility of these valence electrons form one end to another end in a metal will generates electricity. This is called electrical conductivity in metals. Metals: A metal is a material in the form of an element, compound, or in the form of alloy and which is basically hard when it is in solid state. Metals are good conductors and shows electrical conductiviy and thermal conductivity. Due to electron delocalization in conduction band metals shows electrical property. Metals have wide range of applications in industries and our daily life.

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
