1. The Basics Balancing Equations

2. The Reaction Burning METHANE or any hydrocarbon gives WATER and CARBON DIOXIDE Burning METHANE or any hydrocarbon gives WATER and CARBON DIOXIDE The Equation Methane Water Carbon Dioxide Carbon Dioxide from burning in air CH 4 + O 2 H2OH2O H2OH2O + CO 2

3. The Reaction CH 4 + O 2 H2OH2O H2OH2O + CO 2 C C H H H H H H H H O O O O Our Methane molecule Our Oxygen molecule

4. The Reaction C C H H H H H H H H O O O O We need ENERGY to get this reaction going

5. The Reaction The ENERGY needs to be enough to break the bonds C C H H H H H H H H O O O O

6. The Reaction The ENERGY needs to be enough to break the bonds C C H H H H H H H H O O O O

7. The Reaction The ENERGY needs to be enough to break the bonds C C H H H H H H H H O O O O

8. The Reaction C C H H H H H H H H O O O O Now all the atoms are free to move

9. The Reaction C C H H H H H H H H O O O O Now all the atoms are free to move

10. The Reaction C C H H H H O O O O Now all the atoms are free to move H H H H

11. The Reaction C C H H H H O O Now all the atoms are free to move and react O O H H H H

12. The Reaction C C H H H H O O Now all the atoms are free to move and react O O H H H H A water molecule

13. The Reaction C C H H H H O O Now all the atoms are free to move and react O O H H H H Another water molecule But what about?

14. The Reaction C C H H H H O O O O H H H H Let’s move these 2 water molecules to one side first

15. The Reaction C C H H H H O O O O H H H H Well, there’s plenty of O2 in the air O O O O O O O O O O O O O O O O As there is ALL the time

16. The Reaction C C H H H H O O O O H H H H The initial energy broke a few more bonds O O O O O O O O O O O O O O O O As there is ALL the time

17. C C H H H H O O O O H H H H O O O O The Reaction These atoms are free to move as well

18. C C H H H H O O O O H H H H O O O O The Reaction These atoms are free to move as well

19. C C H H H H O O O O H H H H O O O O The Reaction and make new bonds

20. C C H H H H O O O O H H H H O O O O The Reaction and make new bonds One CO2 molecule

21. The Equation What we used REACTANTS What we used REACTANTS C C H H H H H H H H One Methane molecule and Two Oxygen molecules O O O O O O O O CH 4 O2O2 O2O2 + + 2 2

22. The Equation What we made PRODUCTS What we made PRODUCTS and One Carbon Dioxide molecule C C O O O O Two Water molecules H H H H O O O O H H H H CO 2 H2OH2O H2OH2O + + 2 2

23. CH 4 O2O2 O2O2 + + CO 2 H2OH2O H2OH2O + + The Equation

24. CH 4 O2O2 O2O2 + + CO 2 H2OH2O H2OH2O + + The Equation 2 2 2 2 Balanced
