Describe what you believe is implied by the term “engagement risk.” What are the key factors likely considered by Deloitte and other audit firms when assessing engagement risk? How‚ if at all‚ are auditors’ professional responsibilities affected when a client proposes a higher than normal degree of engagement risk? I believe that the term “engagement risk” implies that inherent client-specific risks face an auditor throughout the course of an audit‚ thus creating a risk that the auditor will be

What holds the complexes together: The set of ligands are held to a metal ion by largely electrostatic forces (although there really is a high degree of covalency). The forces arise from the positive charge on the metal ion and the electric dipoles of the ligands‚ whose negative ends are associated

constituded by the congugated bonds. These series of reactions synthesize the Schiff Base ligand and Nickel(II) complex of the Schiff base ligand. 0.36g of the Schiff base ligand is yielded and 0.1g of the nickel complex is yielded from the 0.36g Schiff base ligand and 0.5g nickel acetate. Introduction We perform two separate reactions in this experiment in order to obtain Schiff Base Ligand that will substitute the ligands of a nickel hydrated complex.

supervisory roles in auditing public audit firms and individual auditors. This was done through establishment of proper quality control measures on the work of auditors to minimize the audit risks that firms could face while conducting their work. The Ligand Pharmaceuticals case presents a perfect situation where the Sarbanes Oxley act was violated and required the enforcement of the law by the PCOAB. The questions that follow will therefore try to address the auditing provisions that were brought by

hexacyanoferrate(lll) (K3[Fe(CN)6])‚ was already synthesized in Mudie Laboratory. The magnetic moment of K3[Fe(CN)6] was found to be 1.07 MB and that of Fe(acac)3 was found to be 1.43 MB. The ligand CN- was said to be a strong field ligand and its complex was said to be of a low spin. The ligand acac was said to be a weak field ligand and its complex was said to be of a high spin. [K3(acac)3]) had 5 unpaired electrons whereas k3[Fe(CN)6] had 1 unpaired electron. Aim The experiment aim was to determine the magnetic

I. Abstract This experiment aimed to determine the composition of Ni2+- ethylenediamine (en) complexes through Continuous Variations method as well as the number of ligands (n values). This nondestructive method is preferred in determining the amount of complexes present which will also not disrupt the equilibria. 0.3M concentrations of nickel sulfate hexahydrate and ethylenediamene are mixed at certain stoichiometric ratios of 0.3‚ 0.4‚ 0.5‚ 0.6‚ 0.7‚ 0.8 and 0.9 to form several complexes.

Linkage isomerism in cobalt(III) complexes Author: M Hurley Abstract Preparation of nitrito-kO-complex was prepared by ligand substitution from a chloridio-complex chemically made. The nitro-kN-complex was then prepared by isomerisation of the nitrito-kO-complex. Visible absorption and infrared spectroscopy was then carried out on all three complexes. The molar absorption coefficients calculated were 38.0 cm-1 mol-1 L for the chloridio-complex‚ 76.0 cm-1 mol-1 L for the nitrito-kO-complex

In this lab‚ molybdenum hexacarbonyl (Mo(CO)6) was used to synthesize 3 different compounds‚ (η6-C6H3(CH3)3)Mo(CO)3‚ Mo(CO)5dppm and Mo(CO)4C2H6N2. Each of these compounds replaces either 1‚ 2 or 3 carbonyl groups from the Mo center with a different ligand. From these compounds‚ observations about how changing out CO ligands will affect the remaining CO bonds can

They are semiconductor devices that can convert electrical energy directly into light due to the nature of the bonding that occurs in the semiconductor solid. Type of bonding is directly related to conductivity of solid. Bonding in Elemental Solids Electronegativity – the ability of an atom to attract electrons to itself. Atoms with low e.n.
