What is the standard molar enthalpy change of combustion for coconut oil?
Coconut oil is a mixture not a compound.
What is the change of enthalpy associated with the combustion of one mole of pentane The chemical equation is C5H12 8 O2 yields 5 CO2 6 H2O?
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.
Why can't the enthalpy change of combustion of CO2 be measured?
Because you can't combust CO2. CO2 is the final product of the combustion of carbon. You can't combust it further
What is relation between hydration energy lattice energy and enthalpy of solution?
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
What does it mean if the change in enthalpy value for a chemical reaction is positive?
Change in enthalpy value for a chemical reaction is positive is because,there loose of electron(s) in the reaction, and that will change the enthalpy of that particular element from negetive,neutral to positive.
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 is the standard molar enthalpy change of combustion for coconut oil?
Coconut oil is a mixture not a compound.
How do i get the heat of combustion of c25h52?
You're gonna need an enthalpy change of formation table.
The change in internal energy for the combustion of 1.0 of octane at a pressure of 1.0 is 5084.1 If the change in enthalpy is 5074.3 how much work is done during the combustion?
-9.8 kJ
Why is the enthalpy change of combustion for methanol less negative than methane?
The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.

Is energy change involved when a compound is formed?
yes, enthalpy change take place when a bond is either form or break
What is relation between hydration energy lattice energy and enthalpy of solution?
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
The change in enthalpy that accompanies the formation of a compound from its elements?
The energy change that happens when a substance forms from its elements (APEX)
What does it mean if the change in enthalpy value for a chemical reaction is positive?
Change in enthalpy value for a chemical reaction is positive is because,there loose of electron(s) in the reaction, and that will change the enthalpy of that particular element from negetive,neutral to positive.
Why is the enthalpy change of combustion always negative?
It is and exothermic reaction, which means energy is given out heating the surroundings.
