Design a heat exchanger for a process where hot air (80°C) needs to be cooled down to 30°C using water (10°C) as the cooling medium. The flow rate of hot air is 2 kg/s and the desired outlet temperature of the cooled air is 35°C. The maximum allowable pressure drop for air side is 50 kPa and for water side is 100 kPa. Design the heat exchanger using the LMTD (logarithmic mean temperature difference) method and calculate the required area of heat transfer.

Calculate the standard enthalpy change for the neutralization of hydrochloric acid (HCl) with sodium hydroxide (NaOH) in aqueous solution when 50.0 mL of 0.100 M HCl was used and 75.0 mL of 0.075 M NaOH was added. Assume that the specific heat capacity of the solution is 4.18 J/g·K and the density of the solution is 1.00 g/mL.

Calculate the entropy change for the reaction of 2 moles of methane gas reacting with 4 moles of oxygen gas to form carbon dioxide gas and water vapor at a constant temperature of 298 K. The reaction is balanced and the standard entropy values for methane, oxygen, carbon dioxide, and water vapor are given as -0.242, 205.16, 213.74, and 188.72 J/K/mol, respectively.
