The exchange of 2 positive ions between 2 AB + CD = AD + CB Double Replacement reacting compounds, two + two = two + two forming 2 new compounds as a product Reacts with Oxygen to produce energy as heat and light. Most of the time, it is A + O2 = CO2 H2O Combustion ( ) a hydrocarbon reacting one + O2 = CO2 H2O with oxygen, and the outcome is always carbon dioxide and water
