Methanol burns in oxygen to form carbon dioxide and water calculate delta H rxn @ 25 degrees C
Calculate delta H of 2 moles of liquid water starting at 10 degrees Celsius and heated until completely vaporized into H2O gas at 100 degrees C.
"Calculate the delta H of combustion (in kJ) for C2H6(g). Assume water vapor forms during the combustion."
A calorimeter contains 16.0mL of water at 15.0 degrees Celsius. When 2.50 of X (a substance with a molar mass of 68.0g/mol ) is added, it dissolves via the reaction X(s) + H2O(l)>>>X(aq) and the temperature of the solution increases to 28.0 degrees Celsius. Calculate the enthalpy change,...
Calculate the mass of salt needed to bring the freezing point of 200 mL of water from 0 degrees C to -5 degrees C.
Methanol burns in oxygen to form carbon dioxide and water.calculate delta H rxn ,delta S rxn @ 31 degrees C
A calorimeter contains 35.0mL of water at 14.5 degrees C. When 2.20g of X(a substance with a molar mass of 62.0g/mol ) is added, it dissolves via the reactionX(s)+H20(l)= X(aq)and the temperature of the solution increases to 27.0.Calculate the enthalpy change,delta H, for this reaction per mole...
