Question

Напишите уравнения возможных реакции
Zn+HBr
CaO+H3PO4
Cu+HCl
Al(OH)3
SO3+NaOH
K2O+Ca(OH)2

Answer 1

Zn + 2HBr = ZnBr2 + H2
3CaO + 2H3PO4 = Ca3(PO4)2 + 3H2O
Cu+HCl≠
2Al(OH)3 = Al2O3 + 3H2O
SO3 + 2NaOH = Na2SO4 + H2O
K2O + Ca(OH)2 ≠

Answer 2

 Zn + 2HBr -> ZnBr2 + H2
 3CaO + 2H3PO4 -> Ca3(PO4)2 + 3H2O
 2Al(OH)3 -> Al2O3 + 3H2O
 SO3 + 2NaOH -> Na2SO4 + H2O
