Question

Uzupełnij współczynniki:
K + H₂O -> KOH + H₂
Mg + H₂O -> Mg(OH)₂ + H₂
HNO₃ + Na -> NaNO₃ + H₂
H₂ + Cl₂ -> HCl
C₃H₈ + O₂ -> CO₂ + H₂O
Fe + O₂ -> Fe₂O₃

Answer 1

K+H₂O->KOH+H₂ ; 2 Mg+ 2 H₂O ->Mg(OH)₂ + H₂ ; 2 HNO3+ 2 Na-> 2 NaNO3+H₂ ; H₂+ Cl₂ -> 2 HCl. ; C3H8 + 5 O₂-> 3 CO ₂+ 4 H₂O ; 4 Fe + 3 O₂ -> 2 Fe₂O3

Answer 2

1.2K + 2H₂O -> 2KOH + H₂
2.Mg + 2H₂O -> Mg(OH)₂ + H₂
3.2HNO₃ + 2Na -> 2NaNO₃ + H₂
4.H₂ + Cl₂ -> 2HCl
5.C₃H₈ + 5O₂ -> 3CO₂ + 4H₂O
6.4Fe + 3O₂ -> 2Fe₂O₃

CHYBA JEST DOBRZE !!!!
