Interpretation Introduction

(a)

Interpretation:

The number of elements present in the first two rows of the periodic table needs to be determined if the angular momentum quantum number l can have integral values of 0, 1, 2, ……, n+1.

Concept introduction:

A wave function is characterized by three parameters called quantum numbers, represented as n, l and ml, which can describe the energy level of the orbital and the three-dimensional shape of the region in space occupied by a given electron.

Interpretation Introduction

(b)

Interpretation:

The atomic number of the element in the second row and fifth column needs to be determined if the angular momentum quantum number l can have integral values of 0, 1, 2, ……, n+1.

Concept introduction:

To calculate the atomic number of the element present in the second row and in the fifth row, add the number of elements in the first row with five. This will give the atomic number of the particular element.

Interpretation Introduction

(c)

Interpretation:

An orbital-filling diagram for the element with atomic number 12 needs to be determined if the angular momentum quantum number l can have integral values of 0, 1, 2, ……, n+1.

Concept introduction:

A set of three rules called the Aufbau principle guides the filling order of orbitals. They are as follows:

First lower energy orbitals are filled followed by the higher-energy orbitals.

An orbital can hold only two electrons, which must have opposite spins.

It two or more degenerate orbitals are available; one electron goes into each until all are half-full.

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.…
