The pH of 0.010 M solution of HB needs to be determined, if the pH of salt NaB is 9.00 for 0.050 M solution. Concept Introduction: A base is the substance that gives OH - ions in its aqueous solution. On the basis of base dissociation, they can be classified as strong and weak base. On the contrary, a weak base ionized partially and reaches to equilibrium. BOH (aq) ⇌ OH - (aq) +B - (aq) An acid is the substance that gives H + ions in its aqueous solution. On the basis of acid dissociation, acids can be classified as strong and weak acid. On the contrary, a weak acid ionized partially and reaches to equilibrium. HA (aq) + H 2 O (l) ⇌ H 3 O + (aq) + A - (aq)

Interpretation Introduction

Interpretation: The pH of 0.010 M solution of HB needs to be determined, if the pH of salt NaB is 9.00 for 0.050 M solution.

Concept Introduction: A base is the substance that gives $OH-$ ions in its aqueous solution. On the basis of base dissociation, they can be classified as strong and weak base. On the contrary, a weak base ionized partially and reaches to equilibrium.

$BOH(aq)⇌OH-(aq)+B-(aq)$

An acid is the substance that gives $H+$ ions in its aqueous solution. On the basis of acid dissociation, acids can be classified as strong and weak acid. On the contrary, a weak acid ionized partially and reaches to equilibrium.

$HA(aq)+ H2O(l)⇌H3O+(aq)+ A-(aq)$

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

An expression for the root mean square velocity, vrms, of a gas was derived. Using Maxwell’s velocity distribution, one can also calculate the mean velocity and the most probable velocity (mp) of a collection of molecules. The equations used for these two quantities are vmean=(8RT/πM)1/2 and vmp=(2RT/M)1/2 These values have a fixed relationship to each other.(a) Arrange these three quantities in order of increasing magnitude.(b) Show that the relative magnitudes are independent of the molar mass of the gas.(c) Use the smallest velocity as a reference for establishing the order of magnitude and determine the relationship between the larger and smaller values.
