Chapter 7, Problem 7.35QE

(a)

Interpretation Introduction

Interpretation:

The longest wavelength of light that can eject electrons from a sample of solid carbon has to be determined.

Concept Introduction:

The wave nature of any light can be described by its frequency, wavelength, and amplitude. The wavelength (λ, lambda) of the light is defined as the distance between two successive peaks. Its SI unit is meter. The frequency (v) is defined as number of waves that can pass through the one point in 1 second. Its SI unit is s1. The amplitude (A) of the light wave is maximum height of a wave.

The relation between frequency (v) and wavelength (λ) of the light is as follows:

  v=cλ        (1)

Here, c is the speed of light and its value is 3.00×108 m/s.

(b)

Interpretation Introduction

Interpretation:

The spectral region of an electron ejected from a sample of solid carbon has to be determined.

Concept Introduction:

Refer to part (a).

Please help me with # 4 and 5. Thanks in advance!
A small artisanal cheesemaker is testing the acidity of their milk before it coagulates. During fermentation, bacteria produce lactic acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and develop flavor. The cheesemaker has measured that the developing mixture contains lactic acid at an initial concentration of 0.025 M. Your task is to calculate the pH of this mixture and determine whether it meets the required acidity for proper cheese development. To achieve the best flavor, texture and reduce/control microbial growth, the pH range needs to be between pH 4.6 and 5.0. Assumptions: Lactic acid is a monoprotic acid H H :0:0: H-C-C H :0: O-H Figure 1: Lewis Structure for Lactic Acid For simplicity, you can use the generic formula HA to represent the acid You can assume lactic acid dissociation is in water as milk is mostly water. Temperature is 25°C 1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to include state symbols.…
