The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to product. Consider the reaction: P4(s) + 6 Cl2(g) -*4 PCI3(1) If 11.18 g P4 is mixed with 18.56 g Cl2, calculate the theoretical yield (g) of PCl3 produced by the reaction. Solution Number of moles of P4 = 11.18 g / 123.90 g/mol = 0.0902 mol Number of moles of Cl2 = 18.56 g / 70.9060 g/mol = 0.262 mole From the balanced equation we can say that 1 mole of P4 requires 6 mole of Cl2 so 0.0902 mole of P4 will require = 0.0902 mole of P4 *(6 mole of Cl2 / 1 mole of P4) = 0.541 mole of Cl2 But we have only 0.262 mole of Cl2 which is in short so Cl2 is the limiting reactant 6 mole of Cl2 produces 4 mole of PCl3 so 0.262 mole of Cl2 will produce = 0.262 mole of Cl2 *(4 mole of PCl3 / 6 mole of Cl2) = 0.175 mole of PCl3 mass of 1 mol of PCl3 = 137.33 g so the mass of 0.175 mole of PCl3 = 24.0 g Therefore, theoretical yield of PCl3 = 24.0 g .

The sale of stock and the sale of bonds are reported as financing activities. Are payments of dividends to shareholders and payments of interest to bondholders also reported as financing activities? Explain. Solution The payment of cash dividends to shareholders is classified as a financing activity. FINANCING ACTIVITIES include transactions between the company and its owners and creditors. That is, they include the sale or buyback of stocks or bonds issued by the company and dividend payments by the company to its shareholders. In general, changes involving noncurrent liabilities and stockholders\' equity are reported in the financing activities section. Note the difference between investing and financing activities in the context of the purchase and sale of stocks and bonds. When you buy or sell the stock or bond issued by someone else, it is considered an investing activity. When you issue (sell) or buy back stock or bonds that you had issued, it is considered part of a financing activity. Cash inflows from financing activities arise when the company issues stock or borrows (by issuing a bond or by signing a note, or otherwise). Cash outflows from financing activities arise when the company buys back its own stock or bonds, repays loans, or pays dividends to shareholders. Note that dividends paid to shareholders are considered to be part of financing activities, but interest paid to bondholders is included only as an operating activity. Furthermore, as noted earlier, both dividend and interest revenues received by the company are included in cash flows from operating activities section. NONCASH INVESTING AND FINANCING ACTIVITIES include noncash transactions that effect both noncurrent assets and noncurrent liabilities or owners\' equity. .

Precipitation volumetric analysis involves formation reactions of soluble compounds. What are the main factors that influence conditions for a successful analysis? Explain how these factors may influence the profiles of the titration curves. Solution Following factors influence the precipitation volumetric analysis. 1. Nature of solvent- polarity is directly proportional to the precipitation formation. More polar the solvent more the precipitation. 2. Ph of solution is directly proportional to the precipitation formation. More acidic solutuons form precipitate readily than basic solutions. 3. Concentration of solution is directly proportional to the precipitation formation. Diltue solution form less stable precipitate. 4. Formation of low solubility product in precipitation titration decrease the end point in titration. This can be overcome by adjusting ph. 5. Temperature is directly proportional to the precipitation. 6. Foreign elements present decrease the stability of product as they can show coprecipitation. 4. .

Prioritize the three themes of integrated solid waste management. 1^st priority 2^nd priority 3^rd priority Solution 1.Waste Prevention:Waste prevention also called â€œsource reductionâ€seeks to prevent waste from being generated. Waste prevention strategies include using less packaging, designing products to last longer, and reusing products and materials. Waste prevention helps reduce handling, treatment, and disposal costs and ultimately reduces the generation of methane 2.Recycling and Composting: Recycling is a process that involves collecting, reprocessing, and recovering certain waste materials (e.g., glass, metal, plastics, paper) to make new materials or products. Some recycled organic materials are rich in nutrients and can be used to improve soils. 3.Disposal (landfilling and combustion). These activities are used to manage waste that cannot be prevented or recycled. One way to dispose of waste is to place it in properly designed, constructed, and managed landfills, where it is safely contained. Another way to handle this waste is through combustion. .

Prepare a 3 to 5 paragraph briefing statement which explains the 3 most important reasons why a company should invest in cybersecurity tools and technologies. Your audience is a group of managers (technical and non-technical) who are participating in a conference on reducing risks associated with insider threats. Provide in-text citations and references for 3 or more authoritative sources. Put the reference list at the end of your posting. Solution Reason One The increasing use of Internet of Thing In business organization the Internet of thing means the addition of devices which can access the organization data and increase in number of threats of security flaws. Since these devices werenâ€™t originally registered on network, they may not have enough cybersecurity protections. so it become easy for cyber criminals to use a device to gain unauthorized access to the hidden data of the organization. Reason 2 The Breaches are a financial burden Whenever a breach is discovered, systems are often taken offline to plug the security holes as a result of which the organization may not be able to take more customer order and to fullfil the last order placed, hence it become necessary to include cybersecurity to reduce such financial burden on organization. Reason 3 the real threats are insider threats The fraud employee sometimes inflict tremendous harm to take revange with organization or to have a personal profit. The risk associated with this type of threat is that it is very difficult to find such internal loop holes. Reason 4 Without cybersecurity the reputation of the organization is at risk. If the organization does\'nt opt the cybersecurity strategy then customer always think that there data is at risk and they will diverge from the organization which really harms the reputation of the organization .
