Question

No2. Закончить уравнения возможных реакций: Ba(OH)2 + H2SO4 =
Fe(OH)3 + HNO3 =
Cu(OH)2 + MgO =
Na2CO3 + HCl = Pb + H3PO4 = Zn + HCl =

Answer 1

Ответ:

Ba(OH)2+H2SO4=BaSO4+2H2O

Fe(OH)3+3HNO3=Fe(NO3)3+3H2O

Cu(OH)2+MgO=CuO+Mg(OH)2

Na2CO3+2HCl=2NaCl+H2CO3

2Pb+2H3PO4=2PbPO4+3H2

Zn+2HCl=ZnCl2+H2
