Copper and silver nitrate (single displacement with copper (II) compound formed).
Hydrochloric acid and silver nitrate (double displacement).
Magnesium and oxygen (synthesis).
Decomposition of zinc oxide to its elements.

Answer 1

1. Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag

2. 2HCl + AgNO3 -> 2HNO3 + 2AgCl
3. 2Mg + O2 -> 2MgO
4. 2ZnO -> 2Zn + O2
