help me please so i know how to solve future problems. show with clear steps showing the answer. thankyou

(10 pts) Give an example of an industrial application where Raoult's law and Dalton's law have to be used in their calculations. (10 pts) Explain in your own words. Q2(25 pts) A closed tank contains mixture of Methanol and Ethanol at a temperature of 70C. The liquid phase contains 30% of Ethanol. a) (10 pts) Calculate the partial pressures of Methanol and Ethanol in the vapor phase. b) (5 pts) Calculate the total pressure of the vapor phase. c) (10 pts) Calculate the composition of the vapor phase. Q3(25pts) The water is at the pressure of 0.3 bar and temperature of 30C. a) (10 pts) Use Antoine equation to calculate the temperature at which the water will boil. b) ( 5 pts) State if the water is in the condition of subcooled liquid, saturated liquid/steam or superheated steam. c) (10 pts) Calculate the degree of superheating or / subcooling Q4 (25 pts) a) (15 pts) If humid air at 1 bar, 70C has a 15% relative humidity, how much is the molar percentage of water in that humid air? b) (10 pts) Explain how the relative humidity can be affected by the temperature and the total pressure, with the molar fraction of water in the air remaining the same
