Calculate the heat of mixing when 50g of ethanol (C2H5OH) is added to 200g of water initially at 25°C. Assume the density of water is 1g/mL and the specific heat capacity of water is 4.184J/(g°C). The enthalpy of vaporization of ethanol is 38.56kJ/mol and assume that ethanol-water mixture has a specific heat capacity of 4.2J/(g°C).

A Chemistry student is trying to determine the effect of changing the volume on the equilibrium position of a chemical reaction at constant temperature. If the reaction is initially in equilibrium in a 1 L container with a concentration of [X] = 0.10 M and [Y] = 0.20 M, and then the volume is decreased to 0.4 L, what will be the new equilibrium concentrations of X and Y at the new volume?
