Bonjour , voici un exercice que je n'arrive pas à résoudre. Quelqu'un pourrait m'aider ? Merci d'avance : Ajuste les équations de réactions suivantes
1. 2C+ ..... O2 -> .....CO2
2.
..... CO2 + ..... H2O → .....C6H12O6+ ..... O2
3. 2 C4H10 + .... O2 → ...CO2+ ....H2O
Reproduire le modèle de l'équation chimique :
3 C + 3 02. → 3 CO2
Le modèle est-il équilibré, si oui pourquoi ?
