  Bonjour,

  Je travaille sur l’osmose et la diffusion, et je me demandais si un œuf (normal, sans cuisson) s’agirait d’un osmose ou diffusion, mais je ne sais pas quoi faire sachant qu’il n’y a eu aucune transformation.

  Aussi, j’aimerais avoir de l’aide sur un œuf qui aurait été dans du colorant/l’intérieur de l’œuf pour établir le changement/osmose,diffusion.

  Merci!

  Hello there, l had a question:

  How come roaches are immune to Radiation and waves, such as micro-waves?

  Radiation literally means the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei. Disintegration... How are roaches not disintegrated? Are they NOT made of atoms?

  Bonjour, nous avons un laboratoire sur les concentrations demain et on nous dit « Vous devez rédiger le rapport de laboratoire dans le but de préparer 50ml de solution À à 18000 ppm et de 100 ml d’une solution B à 0,115 mol/L avec un soluté qui est le C12H22O11. Tu dois utiliser de l’eau distillée pour faire les deux solutions. »

  
  

  Est-ce que quelqu’un pourrait m’aider à calculer la concentration de la solution B svp?
