Write a balanced chemical equation for each of the following reactions in a word processor.

1. A solution of glucose (C₆H₁₂O₆) ferments without oxygen to produce a solution of ethanol(C₂H₅OH) and carbon dioxide gas.
2. In the process of photosynthesis, plants use carbon dioxide and water to make glucose(C₆H₁₂O₆) and oxygen.
3. A solution of silver nitrate reacts with a solution of potassium phosphate to produces a yellow precipitate of silver phosphate.
4. Sodium bi-carbonate, NaHCO₃ and vingear, CH₃COOH react to produce carbon dioxide, water and a salt.
5. In the Haber process nitrogen and hydrogen gas combine to produce ammonia
6. In the Solvay process calcium carbonate and sodium chloride are used to produce calcium chloride and sodium carbonate via a indirect pathway.
7. Brown nitrogen dioxide gas combines with water to produce a mixture of nitric acid and nitrous acid.
8. Sodium oxide dissolves in water to produce a strong alkali solution
9. Lithium hydroxide is used in space missions to remove carbon dioxide from the air. Lithium carbonate and water are produced.
10. Colourless nitrogen monoxide combines with oxygen to produce brown nitrogen dioxide.
