Ice at -10 degrees C and steam at 130 degrees C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 50.0 degrees C is present. Ignoring the container and the equilibrium vapor pressure of the liquid at 50 degrees C, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 2020J/(kg degree C). Explain everything you´ve done.
Calculate the enthalpy change upon converting 1.00 mol of ice at -25 °C to steam at 125 °C under a constant pressure of 1 atm
Calculate the enthalpy change upon converting 1.00 mol of ice at -25 °C to steam at 125 °C under a constant pressure of 1 atm. The specific heats of ice, liquid water, and steam are 2.03, 4.18, and 1.84 J/g-K, respectively. For H2O, ΔHfus = 6.01 kJ/mol and ΔHvap=40.67 kJ/mol.

Propane (g) is heated from 20°C to 200°C at 2.5 bar. Steam at 200°C and 5.0 bar enters the same heater and exits as a saturated liquid at the same pressure. Taking a basis of 100 mole of propane fed to the exchanger, calculate the values of the specific enthalpies (H) in the following table. The specific volume of propane is 0.0104 m3/mol. Use the gas constant table for conversions if necessary. Species Specific Specific Enthalpy Enthalpy C3H3 100 mol...

Ice at −12.0 °C and steam at 122 °C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 46.0 °C is present. Ignoring the container and the equilibrium vapor pressure of the liquid, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 2020 J/(kg.C°).

a. One kilogram of ice at -20°C is heated to 0°C and melted. The resulting water is heated to 100°C. The water vaporizes and the steam is heated to 400°C. Assume that all of the processes are isobaric, and calculate the change in enthalpy in Joules. The specific heats (at constant pressure) of ice, liquid water, and steam are 2.30, 4.18, and 2.01 kJ/kgoC respectively Calculate the change in enthalpy for the combustion of one mole of glucose according to...

Calculate the final equilibrium temperature when 10.0 grams of steam initially at 100 degree C is mixed with 450 grams of liquid water and 110 grams of ice at 0 degree C in a calorimeter. That is, the liquid water AND the ice are initially at 0 degree C. Ignore any heat energy exchanges with the calorimeter and the surroundings. If you conclude that the final temperature of the system is 0 degree C, then what mass of ice remains,...
