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...

All parts of one question. please help
The common laboratory solvent water is often used to purify substances dissolved in it. The vapor pressure of water is 23.76 mm Hg at 25 °C. In a laboratory experiment, students synthesized a new compound and found that when 79.28 grams of the compound were dissolved in 211.4 grams of water, the vapor pressure of the solution was 23.30 mm Hg. The compound was also found to be nonvolatile and a non-electrolyte. What...
