Ответ:
Объяснение:
A)
4Al + 3O2 = 2Al2O3
Al2O3 + 6HBr = 2AlBr3 + 3H2O
AlBr3 + 3NaOH = Al(OH)3 + 3NaBr
2Al(OH)3 =t= Al2O3 + 3H2O
Al2O3 + 3H2S = Al2S3 + 3H2O
Б)
ZnSO4 + 2NaOH = Zn(OH)2 + Na2SO4
Zn(OH)2 =t= ZnO + H2O
ZnO + 2HI = ZnI2 + H2O
B)
MgCl2 + H2SO4 = MgSO4 + 2HCl
MgSO4 + BaCl2 = MgCl2 + BaSO4
3MgCl2 + 2K3PO4 = Mg3(PO4)2 + 6KCl
