You have 500 g of dry ice at a temperature of 50 K. How much energy would it take to produce carbon dioxide gas heated to a temperature of 400оC?   Specific heat of CO2(s) = 0.709 J/g K     Specific heat of H2O(s) = 2.040 J/g K Specific heat of CO2(g) = 0.850 J/g K                             Specific heat of H2O(l) = 4.184 J/g K Specific heat of H2O(g) = 2.010 J/g K Freezing point (CO2) = -78.5оC                                                          Freezing point (H2O) = 273.15 K Latent heat of sublimation (CO2) = 199 J/g Latent heat of fusion (H2O) = 334 J/g     Latent heat of vaporization (H2O) = 2260 J/g

. Based on what you have studied about intermolecular forces, predict which of the following liquid has the highest boiling point and why. All three compounds have comparable molecular weights.   Butane, C4H10                          Propanol, C3H7OH                . Acetone, CH3COCH3

You have samples of four compounds: dimethyl ether, methane, difluoromethane, and ethanol. You measure the boiling points of the compounds as -128 °C, -52 °C, -25 °C, and 78 °C, but then lose the labels for each sample. Make the following predictions Which compound boils at -128 °C?
