How are bonds formed and broken
Webquestions about the neutralisation reaction of NaOH (aq)+HCl (aq)-->NaCl (aq) Are there three stages to it. - 1 The bonds are broken. NaOH breaks to Na and OH. HCl breaks to H and Cl. - 2 Bonds are formed, NaCl is formed, and energy is produced in the NaCl solution. And the energy from the formation of the bonds, is transferred into the NaCl ...

It takes energy to break bonds (positive enthalpy) and releases energy to form bonds (negative enthalpy) and then you add those enthalpies together. You could also do broken-formed but make sure you use bond enthalpies directly. Top. Hellen Truong 2J. Posts: 50. Joined: Sat Jul 22, …
