Crazy Rocket Demonstration Notes
2
Equation for the reaction

• (C6H10O5)n(s) O2(g) ?
  CO2(g) H2O(g)

wood oxygen produces
carbon dioxide water
3
Reaction Type

• Combustion
• Any reaction where a substance (usually a
  hydrocarbon) is combined with oxygen to produce
  carbon dioxide and water

4
Energy changes

• Because heat is released in this reaction it is
  called an exothermic reaction.

5
Why does the rocket lift off?

• The heat produced heats the air inside the
  rocket hot air is less dense than cooler air,
  so the rocket lifts off.
