In a closed container, one gram of water (1 cm) is boiled under constant pressure of 1 atm (1.013 10Pa) until it changes into steam. The heat of vaporization at this pressure is Lv = 2.256 x 106J/kg = 2256 J/g. Assume that water vapor behaves like an ideal gas. The temperature of the steam is 373 K, number of moles of water vapor n = 0.0546 (g mol), the ideal gas constant R = 82.057 (cm3.atm/g mol-K). (a) How...

Please answer 12-17 and show work. I’m not sure which equations to use 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...
Someone help me with question(b) and (c),thx!! (40 %) For a 1-mm-diameter n-hexane droplet burning in air at atmospheric pressure. Assume no heat is conducted into the interior of the liquid droplet and 4. that the droplet temperature is equal to the boiling point. The ambient air is at 298 K. (a) Estimate the mass burning rate of the droplet (b) Calculate the ratio of the flame radius to droplet radius (c) Calculate the flame temperature (d) Plot the temperature...

1.) Determine the enthalpy change when 62.0 g of steam at 135.0 oC is cooled to ice at –15.0 oC. Use the actual enthalpy and heat capacity values 2.) A heater in a hot water tank gives off 30,000 KJ per hour. The initial temperature of 450 kg of water in the tank is 18.0 oC. If the tank is heated for 90 minutes, determine the final temperature of the water. 3.) In general boiling and melting points increase with...
"Vapor Pressure of Water" assignment: VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...
if u can show how u do each one, that would be amazing! How much heat is required to convert 90 g of ice at - 40.0°C into water at 60.0°C? The specific heats (Cs) of ice, water, and steam are 2.09 J/gK, 4.18 J/gK, and 1.84 J/gK, respectively. For H0 AH A) 60.1 kJ = 6.01 kJ/mol, and AH B) 18.8 kJ -40.67 kJ/mol. C) 45.1 kJ D) 37.6 kJ E) 30.5 kJ 11. What is correct for a...
760 You perform the Dumas method experiment. The mass of the empty flask with a boiling stone it is 32.5500 g. After you add the volatile liquid, heat the flask, and condense the remaining liquid, the mass of the flask with the boiling stone and condensed liquid is 33.8802 . The temperature of the water bath is 99.5°C. Atmospheric pressure when you perform the experiment is 745 mm Hg. The volume of the flask is 272 mL. a) Calculate the...
