A liquid mixture of n-hexane and n-heptane is to be flashed. How much energy per second is required to heat 1 mol/s of a mixture of 75 mol% n-hexane and 25 mol% n-heptane from 25ºC to 75ºC at 1 atm pressure (with vapor and liquid product streams leaving at 75ºC at equilibrium)? Also find the vapor and liquid product flowrates and compositions.
The combustion of hexane is given by the following reaction. 2 C6H14 + 19 O2 12 CO2 + 14 H2O The enthalpy of reaction is −4163.0 kJ/mol. How much energy (in joules) will be released if 82.22 grams of hexane is burned. (Molar mass of hexane = 86.20 g/mol). J
you decided to investigate how much energy it would take to get solid acetone to gaseous acetone. So assuming you took 125 g of -100 degree Celsius solid acetone and heated it 56 degree Celsius gaseous acetone, how many joules of energy would be required to do this? Acetone has a melting point of -95 degree Celsius and a boiling point of 56 degrees Celsius. The heat of fusion (melting) is 98 j/g and the heat of vaporization is 538.9...
