Chemical Reactions


1. Explain what a combustion reaction is.
A combustion reaction is a series of chemical reactions between a fuel and an oxidant. In this combustion there is a production of heat, light or both visually seen as a glow or flames.

2. Discuss the demonstration (and show the balanced equation) we saw in class involving reaction exploding hydrogen.
In class we saw the example of the balloon with hydrogen in it, it exploded once we put the fire under it. At the end what was left was H2O and heat. The balanced equation was 2H2 + _O2 à 2 H2O + Heat.

3. Discuss how combustion reactions drive our experiment.
Combustion reactions drive our experiment because in order for it to work we need the combustion heat and propane to have the reaction of moving the flames. So when we see the waves moving we know how the sound waves work.

4. Show the balanced equation for propane combustion.
C3 H8 (g) + 502 (g) à 3CO2 (g) + 4H2O(I)
