What is the experimental molar heat of combustion of methane?
The standard enthalpy of combustion for methane is -890 kJ/mol.
How do you calculate the molar enthalpy of combustion?
To calculate the molar enthalpy of combustion, you need to measure the heat released when one mole of a substance is completely burned in oxygen. This can be done using a calorimeter to measure the temperature change and applying the formula: H q/moles.
How do you find the heat of combustion for 100 grams of trimyristin?
To find the heat of combustion for 100 grams of trimyristin, you would first calculate the molar mass of trimyristin (the sum of the atomic masses of all the atoms in a molecule of trimyristin). Then, use the heat of combustion values for each element in the compound to determine the total heat of combustion for trimyristin. Finally, convert this value per mole of trimyristin to the heat of combustion for 100 grams.
The molar heats of sublimation and fusion of iodine are 62.3kjmol and 15.3kjmol respectively calculate the molar heat of vaporization of liquid iodide?
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
The heat of combustion of heptane is 4817 kj per mol How much heat would be released if 250 kg of heptane undergoes complete combustion?
First, calculate the number of moles in 250 kg of heptane by dividing the mass by the molar mass of heptane (C7H16). Then, multiply the number of moles by the heat of combustion to find the total heat released. Finally, convert the result to kilojoules.
What is the experimental molar heat of combustion?
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
What do you call the heat released when 1 mole of a substance undergoes complete combustion?
You think probable to molar heat, expressed in J/mol.
What is the experimental molar heat of combustion of methane?
The standard enthalpy of combustion for methane is -890 kJ/mol.
How do you figure out molar heat of combustion of phenol at 25 degrees celsius?
The molar heat of combustion of phenol can be calculated by measuring the heat released when a known amount of phenol is completely burned in a calorimeter. The heat released is then used to calculate the molar heat of combustion using the mass of phenol burned and the molar quantity of phenol. This calculation can be done using the formula: heat released = molar heat of combustion x moles of phenol.
What is the heat combustion per gram of quinone?
The heat of combustion of quinone is approximately 2219 kJ/mol. To convert this to per gram basis, we need to know the molar mass of quinone. Quinone has a molar mass of about 108.1 g/mol. Therefore, the heat of combustion of quinone per gram is approximately 20.5 kJ/g.
What is the molar enthalpy of formation of propanol?
The molar enthalpy of formation of propanol (C3H7OH) is approximately -455 kJ/mol. This value represents the heat released when one mole of propanol is formed from its elements in their standard states at 25°C and 1 atm.

What is the standard molar enthalpy change of combustion for coconut oil?
The standard molar enthalpy change of combustion for coconut oil is approximately -3,687 kJ/mol. This value represents the amount of heat released when one mole of coconut oil undergoes complete combustion in excess oxygen.
The molar heats of sublimation and fusion of iodine are 62.3kjmol and 15.3kjmol respectively calculate the molar heat of vaporization of liquid iodide?
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
