A 3.00-g sample of aluminum pellets (specific heat capacity=0.89 J/°C g) and a 18.50-g sample of iron pellets (specific heat capacity = 0.45 J/°C-g) are heated to 100.0 °C. The mixture of hot iron and aluminum is then dropped into 77.4 g water at 22.0 °C. Calculate the final temperature of the metal and water mixture, assuming no heat loss to the surroundings. Final temperature = 20.23 °C An error has been detected in your answer. Check for typos. miscalculations...

On a separate sheet of paper, draw the two alternative chair conformations for the product formed by the addition of bromine to 4-tert-butylcyclohexene. The Gibbs free-energy differences between equatorial and axial substituents on a cyclohexane ring are 21 kJ/mol for tert-butyl, and 2.3 kJ/mol for bromine. Calculate the ratio of the two observed products at 34.0 °C using the following equation: AG° = – RT In Keg The gas constant, R, is 8.314 J/K mol. (Enter your answer to two...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
