Title: Activity 5.2
Course: Chemist€ry > Section: 5. OTHER CHEMICAL REACTIONS

This is the most basic COMBUSTION REACTION

Watch the following applet and write down which are the 2 reactants, which are the 2 products and which are the stoichiometric coefficients.

________________________________________________________________

Now try to find the stoichiometric coefficients for these following combustion reactions:

C_2H_6 + O_2 🡪 CO_2 + H_20

C_3H_8 + O_2 🡪 CO_2 + H_20

C_4H_10 + O_2 🡪 CO_2 + H_20

HELP: In order to find the stoichiometric coefficients, the reaction needs to be balanced. That means we need to keep same number of atoms (for each different element) in both sides of the reaction. This is just because Lavoisier’s law.

But I will give you one more clue or help: Watch this video^6.
