Please show all work and explanations! Calculate ΔE, ΔS, ΔG, Q and W for the vaporization of 3.00 moles of liquid water to form water vapor at 100°C and 1.00 atm pressure. The standard molar enthalpy of vaporization of water is 40.67 kJ/mol. The density of liquid water at 100°C is 0.958 g/cm3 . Assume that the water vapor is an ideal gas, but be careful – the initial state is liquid water, so this is not simply an ideal...

15. The gas above the liquid in a sealed bottle of soda is primarily carbon dioxide. Carbon dioxide is also dissolved in the soda. When the distribution of carbon dioxide between the gas and liquid is hase , , at equilibrium, molecules ofcarbon dioxide in the gas phase can stilldissolve in the iquid they strike the surface and are captured. Similarly, molecules of carbon dioxide can escape...

Question 12: (1 point) What are the values of q, w, ΔU, ΔH, ΔS, ΔSsurr, and ΔSuniv for the following a constant pressure process for a system containing 0.572 moles of CH3OH ? CH3OH(l, 26.0 ºC, 1.00 atm) ⟶ CH3OH(g, 118.0 ºC, 1.00 atm) Assume that the volume of CH3OH(l) is much less than that of CH3OH(g) and that CH3OH(g) behaves as an ideal gas. Also, assume that the temperature of the surroundings is 118.0 ºC. Data: Molar heat capacity for CH3OH(l), Cp,m...

you decided to investigate how much energy it would take to get
solid acetone to gaseous acetone. So assuming you took 125 g of
-100 degree Celsius solid acetone and heated it 56 degree Celsius
gaseous acetone, how many joules of energy would be required to do
this? Acetone has a melting point of -95 degree Celsius and a
boiling point of 56 degrees Celsius. The heat of fusion (melting)
is 98 j/g and the heat of vaporization is 538.9...

I. What is the heat capacity of 185g of liquid water? How many Kilojoules are needed to raise the temperature of 10 kg of liquid water from 24.6°C to 46.2°C and 38.5 mol of water from 38.1°C to 79.4°C? Ans: 774.04J/gC, 903.74Kj, 119.75KJ 2. A 2.200 g sample of quinone, C&402. is burned in a bomb Calorimeter whose total heat capacity is 7.854 kJ C. The temperature of calorimeter increases from 23.44°C to 30.57C. What...

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.
