question:Calculate the mass of silver chloride precipitate produced when 100 mL of 10% w/v AgNO3 solution is reacted with 100 mL of 10% w/v NaCl solution.

answer:Mass of AgNO3 in solution = 10% x 100 mL = 10 g Molar mass of AgNO3 = 169.87 g/mol Moles of AgNO3 = 10 g / 169.87 g/mol = 0.0589 mol Mass of NaCl in solution = 10% x 100 mL = 10 g Molar mass of NaCl = 58.44 g/mol Moles of NaCl = 10 g / 58.44 g/mol = 0.1711 mol The balanced chemical equation for the reaction is: AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) From the equation, 1 mole of AgNO3 reacts with 1 mole of NaCl to produce 1 mole of AgCl. Since AgNO3 is the limiting reagent (0.0589 mol < 0.1711 mol), 0.0589 mol of AgCl will be produced. Molar mass of AgCl = 143.32 g/mol Mass of AgCl precipitate = 0.0589 mol x 143.32 g/mol = 8.43 g Therefore, 8.43 g of silver chloride precipitate will be produced.

question:How do transaction costs on spot and forward exchange markets affect the incentive to invest in foreign-currency securities?

answer:High transaction costs in both the spot and forward exchange markets can discourage investors from investing in foreign-currency securities. This is because transaction costs reduce the effective return that an investor receives from an investment. In addition to the usual risks associated with investing in foreign securities, such as credit risk and political risk, investors in foreign-currency securities are also exposed to currency risk, or the risk that the value of the foreign currency will fluctuate relative to the investor's home currency. Transaction costs add to this risk by increasing the cost of buying and selling foreign-currency securities. As a result, investors may be less willing to invest in foreign-currency securities if transaction costs are high. This can reduce the liquidity of foreign-currency markets and make it more difficult for investors to diversify their portfolios internationally.

question:How many log cabins of each model must Superior Log Cabins, Inc. sell in 2012 to earn a profit of 300,000?

answer:1. Calculate the variable cost per kilowatt-hour and the fixed costs for utilities using the high-low method. 2. Update Table 2 to include the variable cost for utilities. 3. Summarize the information to calculate the target profit sales point. 4. Calculate the sales revenue needed to reach the target profit. 5. Apply the sales mix percentages to the target profit sales revenue to calculate the number of sales units for each model. To earn a profit of 300,000 in 2012, Superior Log Cabins, Inc. must sell approximately 25 basic cabins, 25 deluxe cabins, and 48 standard cabins.

question:How do you add √24 and √54 using prime factorization?

answer:To add √24 and √54, we can follow these steps using prime factorization: 1. Factorize the numbers inside the square roots. 2. Simplify each square root individually. 3. Combine like terms. Prime factorization: 24 = 2^3 * 3 54 = 3^3 * 2 Now, simplify the square roots: √24 = √(2^3 * 3) = √(2^2 * 2 * 3) = 2√2 * √3 √54 = √(3^3 * 2) = √(3^2 * 3 * 2) = 3√3 * √2 Combine the simplified terms: 2√2 * √3 + 3√3 * √2 = (2√3 + 3√3) * √2 = 5√3 * √2 Since √2 is common in both terms, we can factor it out: 5√3 * √2 = √(3^2 * 2) * √2 = 3√(2^2) * √2 = 3 * 2 * √2 = 6√2 Therefore, √24 + √54 simplifies to 6√2.
