Step 1

This is a combustion reaction. We know this because we have a hydrocarbon (C3H8) and oxygen (O2) on the reactant side, which is typical for combustion reactions. Furthermore, the products are carbon dioxide (CO2) and water (H2O), which are always the only two Show more…

Key Concepts

Combustion Reaction

A combustion reaction is a type of chemical reaction where a substance, often a hydrocarbon, reacts rapidly with oxygen, producing carbon dioxide, water, and energy in the form of heat and light. Such reactions are characterized by the complete oxidation of the fuel and are commonly found in processes like burning fuels in engines or fires.

Combination Reaction

A combination reaction, also known as a synthesis reaction, is one where two or more reactants come together to form a single, more complex product. These reactions typically involve elements or simple compounds combining to form a compound with a higher level of chemical organization.

Decomposition Reaction

A decomposition reaction is the reverse of a combination reaction, where a single compound breaks down into two or more simpler substances, such as elements or simpler compounds. This type of reaction often requires an input of energy, such as heat or light, to occur.
