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.
The idea, in English
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.
Explain in Egyptian Arabic
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.
