Combustion Reactions
Combustion reactions are a type of chemical reaction in which a substance combines with oxygen to produce heat, light, and often other products. These reactions are essential for processes such as burning fuel, cooking, and powering engines.
General Equation
The general equation for a combustion reaction is:
fuel + oxygen → carbon dioxide + water + heat
Examples
For example, the combustion of propane (C3H8) can be represented by the following equation:
C3H8 + 5O2 → 3CO2 + 4H2O + heat
Another example is the combustion of methane (CH4):
CH4 + 2O2 → CO2 + 2H2O + heat
Study Guide
- Understanding the Reaction: Learn to identify the reactants and products of a combustion reaction, and understand the role of oxygen as the oxidizing agent.
- Balancing Equations: Practice balancing combustion equations to ensure that the number of atoms on each side of the equation is the same.
- Energy Release: Understand the concept of heat release in combustion reactions and how it relates to the energy stored in the chemical bonds of the reactants.
- Environmental Impact: Explore the environmental consequences of combustion reactions, such as the production of greenhouse gases and air pollution.
- Real-life Applications: Investigate the practical applications of combustion reactions in everyday life, from heating homes to powering vehicles.
By mastering the principles of combustion reactions, you can gain a deeper understanding of the chemical processes that drive many aspects of our daily lives.

Energy
Students who demonstrate understanding can:
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
