Chapter 17, Problem 17.24P

a)

Interpretation Introduction

Interpretation:

The oxidation half reactions have to be balanced and the stoichiometry coefficients have to be given.

Concept Introduction:

Half reactions:

A half reaction can be defined as component of redox reaction that is either Oxidation or reduction reaction. The change in oxidation states of individual substances present in redox reaction gives the half reaction. Half reactions are common methods of balancing redox reactions.

b)

Interpretation Introduction

Interpretation:

The number of molecules of Oxygen that is necessary to balance the half reaction by reduction of Oxygen has to be calculated.

c)

Interpretation Introduction

Interpretation:

The number of moles of Oxygen that would be necessary for oxidation has to be calculated.

d)

Interpretation Introduction

Interpretation:

The chemical oxygen demand of the sample has to be calculated.

e)

Interpretation Introduction

Interpretation:

The concentration in mol/L has to be calculated.

Concept Introduction:

The number of moles per litre of the solution is called as Molarity. Molarity can be defined as the moles of solute (in grams) to the volume of the solution (in litres). The molarity of a solution can be given by the formula,

Molarity(M)=Molesofsolute(ing)Volumeofsolution(inL)

Predict the organic products that form in the reaction below: OH H+ H+ + ☑ Y Note: You may assume you have an excess of either reactant if the reaction requires more than one of those molecules to form the products. In the drawing area below, draw the skeletal ("line") structures of the missing organic products X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure. ✓ m
Determine the structures of the missing organic molecules in the following reaction: + H₂O +H H+ Y Z ☑ ☑ Note: Molecules that share the same letter have the exact same structure. In the drawing area below, draw the skeletal ("line") structures of the missing organic molecules X, Y, and Z. You may draw the structures in any arrangement that you like, so long as they aren't touching. Molecule X shows up in multiple steps, but you only have to draw its structure once.
