Front

What is essential for a combustion reaction to begin?

Back

Fuel, oxygen and heat are essential for a combustion reaction to begin.

Front

What is the word equation for combustion?

Back

The word equation for combustion is: fuel + oxygen → water + carbon dioxide.

Front

What is the initial energy required to start a combustion reaction called?

Back

The initial energy required to start a combustion reaction is called Activation Energy.

Front

Front

Define a double replacement reaction.

Back

A double replacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What are the products of a combustion reaction?

Back

The products of a combustion reaction are typically carbon dioxide and water.

Front

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as an oxidizing agent in combustion reactions, allowing the fuel to react and release energy.

Front

What is the difference between complete and incomplete combustion?

Back

Complete combustion occurs with sufficient oxygen, producing carbon dioxide and water, while incomplete combustion occurs with limited oxygen, producing carbon monoxide and soot.

Front

What is an example of a fuel used in combustion reactions?

Back

An example of a fuel used in combustion reactions is methane (CH₄).
