# Bond breaking and bond forming

> In a reaction the reactants' bonds break (absorbs energy) and new bonds form in the products (releases energy); the balance is the reaction's heat.

> [ar-EG] في أي reaction، الـ bonds اللي في الـ reactants بتتكسر (وده بيمتص energy)، وبتتكوّن bonds جديدة في الـ products (وده بيطلّع energy)؛ والفرق بين الاتنين هو حرارة الـ reaction.
