Mg(NO3)2+Na3PO4=
CaCl2+Na2SiO3=
ZnBr2+KOH=
Na2S+HCl=
Pb(NO3)2+Fe=

Answer 1

Добрый вечер.

Zn + FeCl₂ = ZnCl₂ + Fe
K₂SO₃ + 2HCl = 2KCl + H₂O + SO₂↑
AlCl₃ + 3NaOH = Al(OH)₃ + 3NaCl
2AgNO₃ + Cu = Cu(NO₃)₂ + 2Ag
3Mg(NO₃)₂ + 2Na₃PO₄ = 6NaNO₃ + Mg₃(PO₄)₂
CaCl₂ + Na₂SiO₃ = CaSiO₃ + 2NaCl 
ZnBr₂ + 2KOH = Zn(OH)₂ + 2KBr
Na₂S + 2HCl = 2NaCl + H₂S
Fe + Pb(NO₃)₂ = Fe(NO₃)₂ + Pb
