Bonjour ! 1. Quelle masse d'eau obtient-on ? 1.6g + 6.4g = 8g - 4.4g = 3.6g d'eau. 2. Justifier ? 1.6g (méthane)+ 6.4g (dioxygène) = 8g (le mélange) - 4.4g (dioxyde de carbone obtenu) = 3.6g d'eau.

Uitandu-ma pe fereastra, am vazut in departare niste luminite care mi-au atras atentia. Cand s-au apropiat de geamul meu, am vazut ca era un vehicul neobisnuit. Avea de jur imprejur beculete si o culoare stralucitoare. S-a deschis o usa si a aparut o scara, care ajungea la fereastra mea. Eu, curioasa, am deschis geamul si m-am urcat pe scar
