Calculate the theoretical flame temperature when an equimolar mixture of methane and ethylene at 25°C is burned with 30% excess air preheated to 400°C. *

The lower heating value for gaseous n-octane is 44,791 kJ/kg, and its latent heat of vaporization is 300 kJ/kg. Using this information, determine the enthalpy of formation at 298 K for liquid n-octane in kJ/kmol. (Here you are to compute the enthalpy of formation from the given information, not look it up in a property table.)

in the manufacture of pulp from the delignification process using an operating temperature of 100C. The types of solvents used include acetic acid and ethanol. the other variables are considered the same. why during the delignification process using a temperature of 100 C?

Calculate the heat capacity for formaldehyde at 25°C. Answer should be in kJ/kgmol°C
