Inroduction

Quand on mélange des substances ensemble, il y a souvent une réaction chimique.

BUT

Le but est de déterminer si un mélange d'eau et d'alcool est chimique ou physique.

Hypothèse 

A mon avis il n'y aura aucune réaction chimique mais peu être une réaction physique.

Matériel

MicrosoftTeams-image.png
  • Cylindre gradué x 2​

  • ​100ml d'eau

  • 20ml d'alcool

  • Un bécher

Manipulation

Observation

J'ai observer que quand j'ai mélanger les 2 substances il y a eu une réaction chimique: il y a eu du gaz et il y a eu moins de masse dans le bechère

Conclusion

Après l’expérience j'en ai conclu que même si sa a diminuer de poid en fait les atomes ne disparaissent pas mais s'envole dans les aire

Il faut mettre 100ml d'eau dans un cylindre gradué, 20ml d'alcool dans un autre cylindre gradué et il faut en suite mélanger les 2 substance ensemble dans un bechère
