What is the different between iodine in enthalpy in atomisation and enthalp y of sublimation?

i believe that standard enthalpy change of atomisation is the enthalpy change that takes place when one mole of gaseous atoms is formed from its elements under standard conditions(which includes breaking of bonds between atoms within molecules), while for sublimation it only involves the change of states (from solid to liquid) with no intramolecular bonds broken.

What does the different in potential energy between the reactant and products represent?
It represents the change in enthalpy for the reaction.
What is the difference between enthalpy change and enthalpy change per mole?
Enthalpy is the energy absorbed or lost from a reaction, but enthalpy change per mole is the amount of energy lost per mole, so in order to get the overall enthalpy from the change per mole, you must multiply that value by the amount of moles used in the reaction.
What is the difference between electron affinity and electron gain enthalpy?
electron affinity is the negative of electron gain enthalpy. for example, the electron gain enthalpy of fluorine is -328, and electron affinity is 328 which is -(-328)
How do you determine the enthalpy change of neutralization between HCl and NaOh?
Nats.
How is the enthalpy of reaction related to the enthalpies of formation for the products and reactants?
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
What is the relationship between enthalpy of atomisation of hydrogen and the bond dissociation enthalpy of the H-H bond?
the enthalpy of atomisation of hydrogen is equal and (in principle) identical to the bond dissociation enthalpy of the H-H bond. However, IF the first is measured by calorimetry and the second by spectrometry there might be a systematic difference.
What does the different in potential energy between the reactant and products represent?
It represents the change in enthalpy for the reaction.
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 is the similarity between sublimation and solid?
Sublimation is the direct transformation of a solid in a gas.
What is the difference between enthalpy change and enthalpy change per mole?
Enthalpy is the energy absorbed or lost from a reaction, but enthalpy change per mole is the amount of energy lost per mole, so in order to get the overall enthalpy from the change per mole, you must multiply that value by the amount of moles used in the reaction.

Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
What is the difference between deposit and sublime?
Well first of all; Sublimation is when a solid turns into a gas. This happens in some occasions. For example, dry ice. (Frozen carbon dioxide) And secondly, deposition is when a gas turns into a solid. Deposition and sublimation are quite different. Sublimation is when heat is added. Deposition is when it is cooled.
Which state of matter is not part of the process of sublimation?
Sublimation and Deposition are phases changes that are between gases and solids. This leaves the intermediate step of liquid not part of the process. Sublimation- Solid to Gas Deposition- Gas to Solid
What term refers to the difference between the energy of the transition state and the energy of the reactants?
The different in energy between the products and reactant is known as enthalpy of the reaction, or ∆Hreaction.
