Bonjour,
J'ai un DM à faire en Physique Chimie pour Lundi.
L'exercice consiste à ajuster les nombres stœchiométriques :
...Na+...Cl₂ → ...NaCl
...C+...CuO → ...CO₂+...Cu
...SO₂+...O₂ → ...SO₃
...H₂S+...O₂ → ...SO₂+...H₂O
...NH₃+....O₂ → ...NO+...H₂O
...CU²⁺+...OH⁻ → ...Cu(OH)₂
...CaCO₃ → ...CO₂+...CaO
...CO+...O₂ → ...CO₂
...C₂H₆+...0₂ → ...CO₂+...H₂O
...FeO → ....Fe₃O₄+...Fe
...P₄+...Cl₂ → ...PCl₅
...Cu+...Ag⁺ → ...Ag+...Cu²⁺
Vous devez donc compléter les [...]
Voilà, merci d'avance > v <
