Consider a gas cylinder containing 0.100 moles of an ideal gas in a volume of 1.10 L with a pressure of 1.00 atm. The cylinder is surrounded by a constant temperature bath at 298.0 K. With an external pressure of 5.00 atm, the cylinder is compressed to 0.500 L. Calculate the AS(gas) for this compression process, in J/K.

thermometer. A sample of aluminum, which has a specific heat capacity of 0.897 J'g.°C', is put into a calorimeter (see sketch at right) that contains 100.0 g of water. The aluminum sample starts off at 92.4 °C and the temperature of the water starts off at 15.0 °C. When the temperature of the water stops changing it's 23.2 °C.

Determine the pOH (to two decimal places) of the solution that is produced by mixing 2.23 mL of 2.32x10-4 M SrH2 with 19.9 mL of 1.80×10-1 M SrO.

A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.8608 g sample of glutaric acid (C3HgO4) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.029x103 g of water. During the combustion the temperature increases from 25.01 to 27.84 °C. The heat capacity of water is 4.184 J gl°c-!. The heat capacity of the calorimeter was determined in a previous experiment to be 839.5 J°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of glutaric acid based on these data. C;HgO4(s) + 50,(g) 4 H,O(1) + 5 CO,(g) + Energy Molar Heat of Combustion = kJ/mol

At constant volume, the heat of combustion of a particular compound is -3916.0 kJ/mol. When 1.329 g of this compound (molar mass = 166.62 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter, including its contents, rose by 7.549 "C. What is the heat capacity (calorimeter constant) of the calorimeter? calorimeter constant: kJ/ "C
