Stabiliti coeficienții

K2O+H2O=>KOH
Na2O+H2O=>NaOH
ZrO+H2O=>Zr(OH) 2
Al2O3+H2O=>Al(OH)3
SO3+H2O=>H2SO4
P4O6+H2O=>H3PO3
NH3+H2SO4=>(NH4)2SO4
NH3+HCl=>NHCl4​

Answer 1

Răspuns:

K2O + H2O => 2KOH

Na2O + H2O => 2NaOH

ZrO + H2O => Zr(OH)2

2Al(OH)3 => Al2O3 + 3H2O

SO3 + H2O => H2SO4

P4O6 + 6H2O => 4H3PO3

2NH3 + H2SO4 => (NH4)2SO4

NH3 + HCl => NH4Cl
