1) When sodium hydroxide pellets are added to a solution of sulfuric acid (H2SO4),
sodium sulfate and water are formed.
2) Calcium reacts with sodium fluoride to produce calcium fluoride and elemental
sodium
3) If a copper coil is placed into a solution of silver nitrate, silver crystals form and copper (I)
nitrate is generated.
