Answer 1

Ответ:

1) 4Al + 3O2 = 2Al2O3 (синтез)

2) N2 + 3H2 = 2NH3 (синтез)

3) 3Ca + 2H3PO4 = Ca3(PO4)2 + 3H2 (разложение (замещение))

4) Ba(OH)2 + 2HCl = BaCl2 + 2H2O (двойное разложение)

5) ZnCl2 + 2AgNO3 = Zn(NO3)2 + 2AgCl (обмен)

6) ZnCl2 + 2AgNO3 = Zn(NO3)2 + 2AgCl (обмен)

7) 2KClO3 = 2KCl + 3O2 (разложение)

8) NH4NO3 = N2O + 2H2O (разложение)
