To calculate the entropy change (ΔS) of n-hexane when 1 mol of it evaporates at 341.7 K, we can use the formula: ΔS=ΔHvapT Where:-ΔS is the change in entropy,-ΔH_vap is the enthalpy of vaporization,- T is the temperature in Kelvin. Step 1: Convert ΔH_vap to JoulesGiven...
I know some rigging and packing technicians that have been doing this for years but they aren't engineers, so they won't know nothing about enthalpy of vaporization. Plus they are our client so I'm supposed to be smart engineer with the equations. Regarding the heat required to evaporate...
Because atmospheric pressure is relatively constant, the pressure in the lungs must change to create airflow between the lungs and the outside environment. During inhalation (inspiration), the diaphragm and supporting muscles (intercostal muscles) contract, which results in an expansion of the thoracic...
C_3H_8 + 5 O_2 \to 3 CO_2 + 4 H_2O The enthalpy of reaction is -2202.0 kJ/mol. How much energy (in kilojoules) will be released if 93.48 g of propane is burned? (Molar mass of propane = 44.11 g Calculate the mass of water produced when 5.54 grams of butane reacts w...
Calculate the internal energy (in joules) of an endothermic system that absorbs 457.08 J and expands from 1.0 to 5.22 L against a pressure of 1.54 atm. If 244 KJ heat is released and 35 KJ work done on the system. Calcu...
1Enthalpy and the Loss of Heat Scientists use the term 'change in enthalpy' to describe a gain or loss in energy by a compound or reaction. If the pressure is kept constant, the change in enthalpy can be generally thought of as a change in heat. When a liquid is cooled, it has a ...
