For each of the following problems, write complete chemical equations to describe the chemical process taking place. Balance the equations.

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.

4) When crystalline sugar, C6H12O6 is burned in oxygen, carbon dioxide and water vapor are
formed.

5) Magnesium carbonate combines with hydrochloric acid (HCI) to produce magnesium
chloride water and carbon dioxide gas.
