  1. COMBUSTION REACTIONS By – Sam, Andrew and Robby

  2. Combustion: What is it? • A combustion reaction is when an element or compound reacts with oxygen often producing energy in the form of heat or light. • Hydrogen and Oxygen are always present in a combustion reaction.

  3. Examples of Combustion Lighters Rockets Bombs Fire Grills Cars Furnaces

  4. Complete Combustion Reaction Heat and or Light H O O O O H + C H H CO2 molecule CH4 molecule 2O2 Molecule (Always Present!) 2H2O molecule

  5. Incomplete Combustion Reaction Heat and or Light H H H H H H O O O O + C C C O O O O H H H H H H CO molecule CH4 molecule O2 Molecule Answer:

  6. Balancing a Combustion Equation Balancing a combustion equation is just like balancing a regular chemical equation.

  7. Combustion Concept Practice What substance is common to all combustion reactions? Oxygen and Hydrogen. Helium and Chlorine Mr. Sweeten Heat and Light Name the products of the combustion of a hydrocarbon. • Obama • Water, heat and light • A heatless explosion • Love

  8. Problem Solving Tips • The coefficients in a balanced chemical equation must be simplified.(Like a fraction) 2H2O+2O2 H2O+O2

  9. Homework Questions Write a balanced equation for the complete combustion of C6H6.

  10. Mr. Sweeten
