    In exothermic reactions the enthalpy change is negative, is your enthalpy change negative?

    To determine enthalpy you can look at the bonds broken and formed

    Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process. Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.
