Substance X is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature. Additionally, the values of these other properties of X have been determined: melting point enthalpy of fusion (5. 150- 140- 130. 120- density 110- 80. °C 6.00 kJ/mol 3.00 g/cm³ (solid) 2.50 g/mL (liquid) You may also assume X behaves as an ideal gas in the vapor phase. Suppose a small sample of X at 50 °C is put into an evacuated flask and heated at a constant rate until 10.0 kJ/mol of heat has been added to the sample. Graph the temperature of the sample that would be observed during this experiment. boiling point enthalpy of vaporization heat capacity 125. °C 29.00 kJ/mol 27. J.K1 mol (solid) 15.

Use the phase diagram of Substance X below to find the pressure at which the melting point of X is - 173. °C. 1.6- solid liquid 0.8- gas 100 200 temperature (K) Note: your answer must be within 0.1 atm of the exact answer to be graded correct. atm pressure (atm)

pls help asap! make sure the graph is correct and clear

1. Calculate the amount of heat (in kJ) released when converting 150.2 g of water to ice at -23 degrees Celsius.    2. A closed vessel of volume 10.0 L initially contains 1.303 g of water and no water vapor. Please calculate the mass of liquid water remaining once the system reaches equilibrium at 30 degrees Celsius. The vapor pressure of water at that temperature is equal to 0.0418 atm.   3. A person drinks four glasses of cold water (5 degrees C) every day. The volume of each glass is 195. mL. How much heat (in kJ) does the body have to supply to raise the temperature of the water to 37 degrees C (body temperature)?   4.From these data: N2H4(l) + O2(g) à 2N2(g) + 2H2O(l) H= -622.2 kJ/mol H2(g) + ½O2 à H2O(l) H= -285.8 kJ/mol H2(g) + O­2(g) à H2O2(l) H= -115 kJ/mol Find H for the reaction:                 N2H4(l) + 2H2O2(l) à 2N2(g) + 4H2O(l)   5. Consider the following chemical equation. CH4(g) + 2O2(g) à CO2(g) + 2H2O(l)                 Using the values in the table, calculate…

Prior to the discovery that freon-12 (CF2Cl2) was harmful to the Earth's ozone layer, it was frequently used as the dispersing agent in spray cans for hair spray, etc. Its enthalpy of vaporization at its normal boiling point of -29.2 degree C is 20.25 kJ/mol. Estimate the pressure that a can of hair spray using freon-12 had to withstand at 40 degree C, the temperature of a can that has standing in sunlight.
