WebNov 23, 2016 · The bonds that would be broken are: H-Cl single bond (x 2), Δ H b r e a k = +431 kJ/mol The bonds that would be made are: Mg-Cl single bond (x 2), Δ H m a k e = -406 kJ/mol H-H single bond (x 1), Δ H m a k e = -436 kJ/mol Approximately, Δ H r x n = ∑ Δ H b r e a k − ∑ Δ H m a k e = -386 kJ/mol. WebSep 11, 2024 · The type of energy that breaks the bonds can be light, heat, or kinetic. … WebApr 1, 2024 · It is easier first to think of what happens when a bond is broken in an exothermic reaction. The energy is initially released into vibrations, rotations and translational motion of the two fragments. This energy is then lost as these fragments collide with other gas molecules or with solvent molecules and so eventually ends up as heat. ginger spice indian grocery store
