Slide 6 - Diapositive

What is a combustion reaction and how can you identify them?
  • A combustion reaction is...
  • How can you notice the difference?
  • What is formed? 
C
CO2
H

Slide 7 - Diapositive

How to balance the equation?
The 3-step method
Write down the formula of the combustible and add +O2
Check which atoms are present in the combustible and write down after the arrow CO2/H2O/SO2
Balance the equation

Slide 8 - Diapositive

Example of balancing an equation
We start with sugar (C6H12O6)
Than we add +O2 and CO2/H2O/SO2
Now it looks like:



Slide 9 - Diapositive

Example of balancing an equation
Now we look at the amount of C atoms to the left and bring this amount to the right.
After that we look at the amount of H atoms to the left and bring this amount to the right
After this we look at the amount of O atoms to the right and bring this to the left.
Now it looks like:
