Calculate the enthalpy change when 50 mL of water at 20°C is mixed with 30 mL of ethanol at 30°C. The specific heat capacity of water is 4.18 J g^-1 °C^-1, the specific heat capacity of ethanol is 2.44 J g^-1 °C^-1, and the density of both water and ethanol are 1 g/mL. Assume that the final mixture is at a uniform temperature.
