Question

Coroană!!Ajutor vă rog!!

Completați ecuațiile:

____+Cl2=ZnCl2

Fe(OH)3=>______

_____+HNO3=_____

KOH+___=>Fe(OH)3+H2O

Cu(OH)2+___=>KCL2+___

____+CO2=K2CO3+____

KOH+____=>K2SO4+____

_____+___=>NaNO3+___

____+H2O=>LiOH

_____+____=>Ca(OH)2

Na+___=>NaOH+____

___+H2O=>Ca(OH)2+___

____+____=>Ba(OH)2+__

FeCL2+___=>Fe(OH2)+__

Answer 1

Zn+Cl2->ZnCl2

2Fe(OH)3->Fe2O3+3H2O

la a treia lipseste ceva

6KOH+Fe2O3->2Fe(OH)3+3K2O(uite aici e imposibil sa se dea apa)

Cu(OH)2+K2SO4->CuSO4+2KOH(KCl2 e imposibil sa se dea)

2KOH+CO2->K2CO3+H2O

2KOH+H2SO4->K2SO4+2H2O

Na+HNO3->NaNO3+H2↑

Li2O+H2O->2LiOH

CaO+H2O-Ca(OH)2

Na+H2O->NaOH+H2↑

CaO+H2O->Ca(OH)2+Q(caldura)

BaO+2NaOH->Ba(OH)2+2Na

FeCl2+2NaOH->Fe(OH)2↓+2NaCl
