If 2.50 kg of dry ice (solid carbon dioxide) is added to 1 5.0 L of water with an initial temperature of 24.0 degree C what is the temperature of the water when all of the dry ice has sublimed? For CO_2, the enthalpy of sublimation is 25.2 kJ/mol.
PartA Calculate the amount of heat required to completely sublime 97.0 g of solid dry ice (CO2) at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 kJ/mol. Part B How much heat is evolved in converting 1.00 mol of steam at 155.0 ∘C to ice at -55.0 ∘C? The heat capacity of steam is 2.01 J/(g⋅∘C) and of ice is 2.09 J/(g⋅∘C).
Your instructor gives you a 100 g of dry ice (solid carbon dioxide) at -100 °C. Through the course of an experiment, you end up with 100 g of gaseous carbon dioxide at 0 °C. Answer the following questions based on this data. Assume that no heat is lost to the outside environment during the experiment. The specific heats for solid and gaseous carbon dioxide are 0.296 and 0.203 cal/g-°C respectively. Remember, carbon dioxide sublimes from solid to gas at...
Calculate the amount of heat required to completely sublime 58.0 g of solid dry ice (CO2) at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 kJmol−1.
17.34. Another decorative "ice" sculpture is carved from dry ice (solid CO2) and held at its sublimation point of -78.5 C. What is the entropy change to the universe when the COp sculpture, weighing 389 g, sublimes on a granite tabletop if the temperature of the granite is 12'C and the process occurs reversibly? Assume a final temperature for the CO vapor of -78.5 C. The heat of sublimation of CO2 is 26.1 kJ/mol.
Dry ice, CO2(s), is thermodynamically stable at temperatures below -78 °C. The sublimation of dry ice can be described by the following equation: CO2(s) = CO2(g) What are the signs for the enthalpy, entropy, and free energy change for the sublimation at room temperature? Justify your answer for each thermodynamic value.

Please Help!!!! 13. Carbon dioxide (typically called dry ice when it?s in solid form) transitions between its solid phase and its gas phase at a temperature of -78.5 degree C. Suppose we have 3.12 kg of dry ice at -125 degree C. flow much heat must be added to transform all of the dry ice into gas with an equilibrium temperature of -78.5 degree C? The latent heat of sublimation of dry ice is 5.72 x 10^5 J/kg and the...
A piece of dry ice (solid carbon dioxide) with a mass of 26.0 g sublimes (converts from solid to gas) into a large balloon. Assuming that all of the carbon dioxide ends up in the balloon, what is the volume of the balloon at 18 ∘C and a pressure of 738 mmHg ?
