Calculate the heat of crystallization when 10.0 g of sodium acetate trihydrate (NaCH3COO.3H2O) is dissolved in 100.0 mL of water at 25°C and the solution is allowed to cool to 15°C. The specific heat capacity of the solution is 4.18 J/g °C and the density of the solution is 1.0 g/mL. The heat of solution of sodium acetate trihydrate is -7126 J/mol.

A steel pipe is connected to a copper pipe in a galvanic corrosion couple where the electrolyte is seawater. The corrosion current density of the steel pipe is 3.2 mA/cm2. If the surface area of the steel pipe is 5 cm2, calculate the total amount of charge transferred per hour. Also, calculate the weight loss of the steel pipe per year due to galvanic corrosion, assuming the density of steel is 7.85 g/cm3.
