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
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.
Does energy always released during ionization?
During the formation of anions (negatigely charged ions) energy is released. During the formation of cations (positively charged ions) energy is absorbed.
What kind of energy required to break bonds of reactants and the energy released when products form in an exergonic reaction?
The energy required to break bonds of reactants in an exergonic reaction is activation energy, which initiates the reaction. The energy released when products form is called the released or liberated energy. In exergonic reactions, the released energy is greater than the activation energy, resulting in a net release of 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?
Required
How bond formation and bond breaking related to enthalpy?
Bond formation is an exothermic process, meaning it releases energy, while bond breaking is an endothermic process, meaning it requires energy input. The enthalpy change for a reaction is determined by the difference between the energy released from bond formation and the energy required for bond breaking. If more energy is released during bond formation than is required for bond breaking, the overall reaction is exothermic and vice versa.
Does energy always released during ionization?
During the formation of anions (negatigely charged ions) energy is released. During the formation of cations (positively charged ions) energy is absorbed.
