Here we do experiments and create compounds (which we usually blow up later in the pits). |

| 2Na + 2H2O -> 2NaOH + H2 + heat | The mixing of sodium metal and water. One of the byproducts of the reaction is hydrogen gas. The reaction also produces heat, which ignites the hydrogen. |
| 2Na + Cl2 -> 2NaCl + heat | The production
of table salt from its elemental components. When chlorine gas contacts
sodium metal, salt and heat are produced. The reaction also glows a bright
yellow. |
| (NH4)NaHPO4 -> NaPO3 + NH3 + H2O | The first step in creating phosphorus from ammonium sodium hydrogenphosphate. More on this process can be seen in the phosphorus project file. |
| 4NaPO3 + 2SiO2 + 10C -> 2Na2SiO3 + 10CO + P4 | This is the second step in the creation of phosphorus. In this step, sand and charcoal are added to the sodium phosphite produced in step one. Upon heating, the phosphorus is liberated from the sodium phosphite. |
