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

1) When lithium hydroxide pellets are added to a solution of sulfuric acid (H2SO4), lithium sulfate and water are formed. 

2) Magnesium reacts with sodium fluoride to produce magnesium 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 C6H12O6 is burned in oxygen, carbon dioxide and water vapor are formed. 

5) Calcium carbonate combines with hydrochloric acid (HCl) to produce calcium chloride, water and carbon dioxide gas.
