Question

Va rog ajutati-ma!
este vorba despre ECUATII CHIMICE.
plz
....Fe+...HCl=...Fe Cl2+....H2
....Fe+...HNO3=...Fe(NO3)2+...H2
....Fe+...CuSO4=feSO4+...Cu
...Cu+...O2=..CuO
...Cu+...O2=...Cu2O
...Zn+...HCl=ZnCl2+..,.HCl
...CuCo3=...CuO+..Co2
...NaOH+...HCl=NaCl+...H2O
....Li+...S=...Li2S
...CaO+...H2O=...Ca(OH)2
....FeCl3+...NaOH=...Fe(OH)3+...NaCl

Answer 1

Fe+2HCl=...Fe Cl2+H2
Fe+2HNO3=...Fe(NO3)2+H2
Fe+CuSO4=feSO4+Cu
2Cu+O2=2CuO
4Cu+O2=2Cu2O
Zn+2HCl=ZnCl2+H2
CuCo3=...CuO+..Co2
NaOH+HCl=NaCl+H2O
2Li+S=Li2S
CaO+H2O=Ca(OH)2
FeCl3+3NaOH=Fe(OH)3+3NaCl
