How large would the lattice energy need to be for the formation of NaCl2 to be exothermic?
The lattice energy needed for the formation of NaCl2 to be exothermic would need to be larger than the energy required to break the bonds in Na and Cl2 and smaller than the energy released when the new Na-Cl bonds are formed in NaCl2. This would result in a negative overall enthalpy change for the reaction, indicating an exothermic process.
How can you tell if a reaction is releasing energy?
energy is released when the ATP hydrogen bond breaks, there are three hydrogen bonds by gabriela diaz
What does a negative Hf for a molecule reaction?
A negative enthalpy of formation (ΔHf) for a molecule indicates that the formation of the compound from its constituent elements releases energy, making the reaction exothermic. This suggests that the products are more stable than the reactants, as energy is released during the formation process. In thermodynamic terms, a negative ΔHf implies that the overall process is favorable and tends to occur spontaneously under standard conditions.
Why formation of uni-negative ion is exothermiic process?
Because when the negative ion is form the atom evolves energy for gaining an other electron.The energy evolves in anionic process so the formation of negative ion is an exothermic process.
How Compare the formation of positive ions with the formation of negative ions in terms of energy changes?
The formation of positive ions typically involves the loss of one or more electrons from an atom, which requires energy input to overcome the attraction between the electrons and the nucleus; this energy is called ionization energy. In contrast, the formation of negative ions occurs when an atom gains one or more electrons, a process that usually releases energy, known as electron affinity, as the added electron is attracted to the nucleus. Thus, while the formation of positive ions is endothermic (requiring energy), the formation of negative ions is exothermic (releasing energy).
Why is the enthalpy change of combustion always negative?
The enthalpy change of combustion is always negative because it involves the breaking of bonds in the reactants, which requires energy input, and the formation of new bonds in the products, which releases energy. The energy released during bond formation is greater than the energy required for bond breaking, resulting in a net release of energy, hence the negative value.
What does a negative Hf for molecule mean?
Energy was released when the molecule was formed from its elements
What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.

How would you compare the formation of positive ions with the formation of negative ions in terms of energy changes?
The formation of positive ions typically requires energy input in the form of ionization energy to remove electrons, whereas the formation of negative ions releases energy in the form of electron affinity when electrons are added. Positive ions have higher potential energy compared to their neutral atoms, whereas negative ions have lower potential energy. Overall, the energy changes involved in forming positive and negative ions are opposite in nature.
Is energy released or required for sublimation?
