What is the enthalpy of combustion of ethanol and the equation?
it is a reaction when ethanol compeltly burn in oxygen to produce corbondioxide and water.The reaction is exo because heat is giving off Thom, ab, aba and mer
What is the difference of enthalpy of formation and the enthalpy of combustion?
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
What do the symbols mean Delta Hr Hf Hc Hn Ha in chemistry btw i know theyre enthalpy changes?
delta Hr is the enthalphy change of a reaction delta Hf is the enthalpy of formation where one mole of a substance is formed ( generally in its naturally occurring physical state) delta Hc is the enthalpy of combustion where one mole of a substance in its standard state undergoes combustion delta Hn is the enthalpy of neutralization where one mole of H+ reacts with OH- to form one mole of H2O delta Ha is the enthalpy of atomization where a molecule splits to form its neutral atomic components
Which has a lower enthalpy ethanol or dimethyl ether?
Dimethyl ether has a lower enthalpy compared to ethanol because dimethyl ether has a simpler structure and weaker intermolecular forces, leading to lower enthalpy values. Ethanol has more complex molecular structure and stronger intermolecular forces, resulting in higher enthalpy values.
What is the experimental molar heat of combustion of methane?
The standard enthalpy of combustion for methane is -890 kJ/mol.
What is the standard enthalpy change of combustion of ethanol?
The standard enthalpy change of combustion of ethanol is approximately -1367 kJ/mol. This value represents the amount of heat released when one mole of ethanol is completely burned in excess oxygen to produce carbon dioxide and water.
Why is water identical to the standard enthalpy change of combustion of hydrogen.?
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.

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.
What is the experimental molar heat of combustion of methane?
The standard enthalpy of combustion for methane is -890 kJ/mol.
Ethanol CH3CHO - how to write an equation to represent the enthalpy of formation?
The enthalpy of formation equation for Ethanol (CH3CH2OH) can be written as: CH3CH2OH (l) -> C2H5OH (l) + 3/2 O2 (g) This equation represents the formation of 1 mol of Ethanol from its elements in their standard states at 25°C and 1 atm pressure.
What is the specific enthalpy of combustion of ethane?
The specific enthalpy of combustion of ethane is approximately -1560 kJ/mol.
What is the enthalpy change to burn 37.5 g of ammonia?
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.
What is the standard enthalpy for sodium sulfate?
The standard enthalpy for sodium sulphate is -1387kJ/mol.
