The complete combustion of acetylene C2H2g produces 1300 kJ of energy per mole of acetylene consumed How many grams of acetylene must be burned to produce enough heat to raise the temperature of?
The specific heat, or heat capacity, of the substance having its temperature raised will determine how much the heat affects its temperature. The units of heat capacity are a ratio of energy to the product of mass and temperature degree.
How do you calculate the heat of combustion in kJ/mol?
To calculate the heat of combustion in kilojoules per mole (kJ/mol), you can use the formula: Heat of combustion -H / n Where: H is the enthalpy change of combustion in kilojoules (kJ) n is the number of moles of the substance being combusted This formula helps determine the amount of heat released or absorbed during the combustion of one mole of a substance.
What is the molar heat of combustion of 1-octanol?
The molar heat of combustion of 1-octanol is approximately -6,268 kJ/mol. This value represents the amount of heat released when one mole of 1-octanol is completely burned in excess oxygen to form carbon dioxide and water.
What is the heat of combustion of natural gas?
Natural gas is not just one type of hyrdocarbon, and so its heat of combustion (or enthalpy of combustion) will vary from sources. However, it is primarily formed from methane which has a "heat of combustion" of 889 Kilojoules per mole, you could use that value. Hope that's what you wanted!
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.
