Enthalpy of combusion is energy change when reacting with oxygen. Enthalpy of formation is energy change when forming a compound. But some enthalpies can be equal.ex-Combusion of H2 and formation of H2O is equal
The enthalpy change to burn 37.5 g of ammonia (NH3) can be calculated using the standard enthalpy of formation of ammonia and the balanced chemical equation for its combustion. The enthalpy change will depend on the specific conditions of the reaction, such as temperature and pressure.
To calculate the enthalpy of combustion for a substance, you need to determine the amount of heat released when one mole of the substance is completely burned in oxygen. This can be done by subtracting the sum of the enthalpies of formation of the products from the sum of the enthalpies of formation of the reactants. The enthalpy of combustion is typically expressed in kilojoules per mole.
The chemical formula for ethane is C2H6. When ethane burns, it reacts with oxygen to produce carbon dioxide (CO2) and water (H2O) as products. The balanced equation for the combustion of ethane is: 2C2H6 + 7O2 -> 4CO2 + 6H2O.
The standard enthalpy of combustion for methane is -890 kJ/mol.
To calculate the enthalpy change of formation from combustion, you can use Hess's law, which states that the total enthalpy change for a reaction is the sum of the enthalpy changes for individual steps. First, determine the enthalpy change for the combustion reaction using a calorimeter or from standard enthalpy values. Then, apply the equation: ΔH_f = ΔH_combustion + Σ(ΔH_f of products) - Σ(ΔH_f of reactants), where ΔH_f is the standard enthalpy of formation. This allows you to derive the enthalpy of formation for the desired compound based on its combustion data.

Water is identical to the standard enthalpy change of combustion of hydrogen because the combustion of hydrogen involves its reaction with oxygen to form water. The standard enthalpy change of this reaction is defined by the energy released when hydrogen combusts completely, which results in the formation of water as a product. Thus, the formation of water from hydrogen and oxygen under standard conditions directly correlates to the enthalpy change associated with the combustion process. Hence, the enthalpy change for the formation of water from its elemental components is equivalent to the enthalpy change of hydrogen combustion.

Incomplete combustion of a hydrocarbon typically produces carbon monoxide and water vapor. The word equation for incomplete combustion of ethane, for example, is: ethane + oxygen → carbon monoxide + water
The enthalpy of combustion of a compound is the amount of energy released when one mole of the compound is burned in oxygen, typically measured in kilojoules per mole (kJ/mol). It varies significantly among different compounds based on their chemical structure and the type of bonds present. For example, hydrocarbons generally have high enthalpy of combustion values due to the high-energy carbon-hydrogen bonds. Specific values for compounds can be found in thermodynamic tables or calculated using standard enthalpy of formation data.

i at first wrote out the enthalpies of combustion for hydrogen ethene and ethane and then manipulated the equations , ultimately my answer ended up being -137 but when i tried to find out the enthalpy on google it just came up this quiestion did you find out what the answer was!?
The enthalpy associated with pentane is roughly 1 to 1 when combustion in a vacuum chamber, if you combustion it outside you will have a greater rate of loss from the pentane.
Yes there are. These gases are hydrogen,methane,ethane,propane,butane,pentane. Hope this helped! ;)
The enthalpy change of combustion of CO2 cannot be measured directly because CO2 is already in its most stable form. In combustion reactions, compounds react with oxygen to form more stable products, releasing heat. Since CO2 is already at the end of the combustion process and cannot be further reacted to release more heat, its enthalpy change of combustion cannot be measured directly.
