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...
