Объяснение:

Гидроксид натрия-NaOH

соляная кислота-HCl

оксид магния-MgO

Фосфорная кислота-H3PO4

Сульфат железа(III)-Fe2(SO4)3

хлорид цинка-ZnCl2

Силикат натрия-Na2SiO3

гидроксид цинка-Zn(OH)2

фосфат бария-Ba3(PO4)2

карбонат натрия-Na2CO3

======

1)NaOH+HCl-->NaCl(хлорид натрия)+H2O(вода)

2)MgO+2HCl--->MgCl2(хлорид магния)+H2O(вода)

3)Zn(OH)2+2HCl-->ZnCl2(хлорид цинка)+2H2O(вода)

4)3NaOH+H3PO4-->Na3PO4(фосфат натрия)+3H2O(вода)
