Based on differences in electronegativity, how would you characterize the bonding in sulfur dioxide, SO2? Essay answers are limited to about 500 words (3800 characters maximum, including spaces). 3800 Character(s) remaining Solution The atom with less electronegative is central atom and the atoms with more electronegtive are terminal atoms. So, Sulphur with less electronegative is central atom and Oxygens are terminal atoms. S ( Z = 16 ) 1st excited state electronic configuration is, 1s2 s2 2p6 3s2 3p3 3d1 S in its first exicted state undergoes sp2 hybirdisation due ot which it has 1 paired sp2 hybrid orbital and 2 unpaired sp2 hybrid orbitals. And also S has one p and one d orbital with unpaired electrons. O (Z = 8) E.C is 1s2 2s2 2p4 Each O has two unpaired electrons in its valence shell. The each sp2 unpaired hybrid orbital of S overlaps with one of the unpaired p - orbital ofeach oxygen along the internuclear axis to form single S - O sigma bond with each Oxygen. The reamining unpaired pure p-orbitals of S overlaps with unpaired p - orbital of each oxygen perpendicular to the internuclear axis to form one pi bonds with each oxygen. Still S ia remained with one lone pair of electons. Due to this SO 2 is in bent shape and has the bond angle < 120 0 .

Auditing and Accounting Cases Investigating Issues of Fraud and Professional Ethics 4th Edition Case 2.6 Page 78 1. Refer to the fundamental principles governing an audit. Under the respon-sibilities principle, auditors are required to exercise due care and maintain professional skepticism throughout the audit. Based on the case information, discuss the ways in which the BLMIS auditor, David Friehling, disregarded his responsibility to uphold the fundamental principles governing an audit Solution Based on the facts of the case, due care was not exercised by the auditors. Auditors failed to conduct independent verification of BLMIS assets, review material sources of BLMIS revenue, examine bank account through which client funds flowed, verify liabilities related to client accounts or verify the purchase and custody of securities by BLMIS. This all shows a lack of intent on part of the auditors to gather and evaluate evidence to provide an opinion. Hence, they did not fulfill the Responsibilities principle. The auditor and/ or his relatives had accounts with BLMIS showing lack of professional independence as well. .

b. Impact testing was used to assess which property of the materials? For metals, what crystal structure was more susceptible to the ductile-to-brittle transition temperature? Why was this the case? Solution Answer:- The Imapct testing was used to to asses the required energy to fracture the material and it can be measure the toughness of the material. we can also known the yield strength of material by using impact testing but we dont have any analytical formual for. we can also calcualte the strain rate for its effect on fracture of material. There is BCC and FCC type of crystal which is more susceptible to the ductile to brittle transiotion temperature. the low carbon steel BCC metals, which become brittle at low temperature or at very high strain rate. incase of FCC metals its remain ductiule at low temperature. In metals there is plastic deformation at room temperature occurs due to dislocation motion. this dislocation motion required a stress to move and its depend on the atomic bonding which is a crustal structure. In this case brittle fracture occurs at low temperature and ductile fracture occurs at high temperature. ductile-brittle transformation occured in between low and high temperature. .

B. lonic Bonds: Some atoms have such a strong attraction for electrons (called electronegativity) that they will steal electrons that are loosely held in place from other atoms. The specific structure of an atom will determine whether it gains or loses electrons to form ions. Ion are charged atoms, and atoms electrons have a negative charge (one negative for each extra electron), and atoms which have a positive charge are atoms which have lost electrons Positively charged ions are called cations. Negatively charged ions are anions. Like charges repel, while unlike charges attract (Opposites attract). Cations are then attracted to anions, and together, they will from ionic compounds. 1. Using the periodic table of elements, analyze the following element, ions and compounds. You will be asked to determine the total number of electrons ro protons in the atom or molecule as written. a.

b. Does Rutherford\'s model predict the correct spectrum? Answer: According to Bohr, why did an atom not collapse in on itself while its electrons traveled around the nucleus? (1) 3. Answer: (1) 4. According to Bohr, what is happening in the atom when a photon of light is emitted? Answer: (1) 5. According to Bohr, what is happening in the atom when a photon of light is absorbed? Answer: 6. When you learned about the energy levels of hydrogen, an energy level diagram was introduced. On this diagram, the no energy level was represented. Go to the Hydrogen Atom simulation (Unit D), and complete the n 1 tono transition. Observe the energy state data. a. What is the energy of the n oo energy level? Answer b. If an electron is initially in the ground state, how much energy must be absorbed by the atom for its transition to the oo energy level? Answer: Solution 3) In Bhor\'s model electrons are moving around the neucleous. Neucleus attract the electrons but still they do not fall on neucleus or they do not collapse because due to movement of electron a centrifugal force is also acting on the electron. This centrifugal force and attractive force of neucleus acts as centripetal force and thus electrons do not collapse. 4) According to Bhor when a photon of light is emitting from an atom the electrons are coming to their higher energy state to lower energy state. 5) Similarly when photon of light absorbed by the atom electrons of lower energy states jumps to higher energy state. .

Auditor Solution 1) The auditorâ€™s opinion on internal control is satisfied, because the management has followed all the guidelines and has taken necessary steps for an effective internal control. 2) The auditor has expressed an unqualified opinion on Hewlett Packardâ€™s financial statements, because the auditor observed during the audit that the income statement, cash flow statement, balance sheet and other financial statements show true and fair view figures. Unqualified opinion means the auditor believes that there is no fraud has committed by the client. 3) The paragraph states that when there are permanent limitations like human fallibility, collusion etc. the auditor cannot give assurance whether the internal controls show the misstatements. Without having proper idea, if management or anyone estimates or forecasts the performance or quality of work to be done may lead to risk and the controls which are expected to follow in those estimates or forecasts may become inadequate or useless due change of conditions. Because we cannot expect same performance in every day and the policies and procedures are slowly become worst or useless. .

Net income was reported as $220,000. What is basic EPS? (Round your answer to 2 decimal places.) Solution Basic EPS is the amount of company\'s profit taht is available to its common stock shareholders. As we pay preferred shareholders before common stock holders , so we deduct the preferred dividend. Basic EPS = (Net income - preferred dividend)/ weighted average number of shares Net Income = $220000 Preferred dividend = 600000 x .09 = $54000 weighted number of shares ( assuming that all the shares were held by company for the whole year) = 42000 therefore, Basic EPS = (220000 - 54000)/42000 = $3.95 .

Fill out the following table for four different IT systems. Â·Â Â Â Â Â Â Â Note two enterprise systems they connect with and their connection type. Â·Â Â Â Â Â Â Â Note two security vulnerabilities the connection may have and two to four ways each vulnerability could be potentially exploited. Additional Comments: An example row has been entered into the table in blue. This is only an example and should not limit what you do. Keep in mind that enterprise systems cover a certain task in the enterprise (HR, CRM, Identity Management, etc.). They are not the components of a system (such as servers). Connections can often be a direct connection/pipe, a file, a common database, or something else. The vulnerability is what would make the connection vulnerable to an attack. The related risk is an attack that could target the weakness. Solution When securing the modern enterprise, consider that IT systems do not operate alone. Securing them involves securing their interfaces with other systems as well. It is important to know the different interconnections each system may have.two security vulnerabilities the system may have and 2 to 4 ways each vulnerability could be potentially exploited. IT System Target System Connection Type Possible Security. Vulnerability Related Risk 1. WMOS 2. WCS 3. network(database) 4.Incorrect accessibility 5.System Failures 6. Users accessing items not allowed 7.Users not having access to needed items 8.Loss of data and reboot time 9.Downtime of production A first step to developing an enterprise security plan is to identify the specific vulnerabilities and related risks facing an organization. This list should be fairly exhaustive. Many vulnerability and threat pairs will not make the final cut for remediation, but an organization can only properly prioritize these if it has fully covered all of the risks. .

Figure 9.3 shows an energy diagram for the dissolving of an ionic compound. Discuss what factors are going to tend to make this process more favorable-in other words would likely make the com pound more soluble. Solution Factors that increases the solubility of ionic compounds: Higher the solvent-solute interaction, higher the solubility of ionic compounds in the solvent. As polar solvent dissolve polar solute, ionic compounds are more soluble in polar solvent like water. Polar solvent strongly attract the ions of the solid compound. Common ion effect decrease the solubility of the ionic compounds if the salts ion is already present in the solvent. For example CaSO?(s) ? CaÂ²?(aq) + SO?Â²?(aq) If either of Ca 2+ and SO 4 2- is already present in the solvent the solubility of CaSO4 in the solvent decrease due to common ion effect. For an endothermic reaction increase in temperature increases the solubility of the ionic compound in the solvent as predicted by Le Chatelier Principle. For an exothermic reaction increase in temperature decreases the solubility of ionic compound in the according to Le Chatelier Principle. .

Be specific and provide at least two examples. Solution Cash flow from operating activities is a section of the cash flow statement that provides information regarding the cash-generating abilities of a company\'s core activities. Example: Cash flow from operating activities is generally calculated according to the following formula: Cash Flow from Operating Activities = Net income + Noncash Expenses + Changes in Working Capital The noncash expenses are usually the depreciation and/or amortization expenses listed on the firm\'sincome statement. A statement of cash flows typically breaks out a company\'s cash sources and uses for the period into three categories: cash flows from operations, cash flows from investing activities, and cash flows from financing activities. Cash flows from operations primarily measures the cash-generating abilities of the company\'s core operations rather than from its ability to raise capital or purchase assets The income statement is one of the three primary financial statements used to assess a company .
