Bonds made exothermic
Web- 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 solution causing the temperature of it to increase WebBond Energy What makes a reaction endothermic or exothermic? Why? Chemical reactions can be a lot like playing with Legos ® —you must take apart part of your last creation before you can replace it with something new. For many chemical reactions, we have to first break bonds in the reactants before we can put the atoms back into a new …
