Bonjour j'aurais besoin d'aide pour mon devoir de science je vous préviens déjà c'est en anglais alors je vais vous écrire la question:

Dr Boulos thinks that the bracelet may be made from copper, and the ring may be made from magnesium.
Prof Li thinks that the bracelet may be made from iron , and the ring may be made from silver.

Research these different metals to find out what salts they might form if corroded in the ground.
Describe what you would expect to see when the metals had been underground for some time and compare to the archeologists' observation.


Suggest what chemical tests the archeologists could try on the artifacts to find out what metals they are made from. Outline the procedure for these tests, and describe what you would expect to observe in each case.


Si vous avez compris la question merci de me la traduire en Francis parce que moi je n'ai rien compris et si vous adorez la science et que vous avez tout compris de mon devoirs ça serais gentils de m'aidez merci d'avance,j'aurais besoin d'un réponse ici demain
