Classifying Chemical Reactions

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. Example: Na + Br₂ → NaBr.

Front

What is the general formula for a synthesis reaction?

Back

The general formula for a synthesis reaction is A + B → AB.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a compound breaks down into simpler substances. Example: 2 H₂O₂ → 2 H₂O + O₂.

Front

What is the general formula for a decomposition reaction?

Back

The general formula for a decomposition reaction is AB → A + B.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD → AD + CB.

Front

What is a combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH₄ + 2 O₂ → CO₂ + 2 H₂O.

Front

What is the difference between synthesis and decomposition reactions?

Back

Synthesis reactions combine simpler substances to form a complex product, while decomposition reactions break down a compound into simpler substances.

Front

What is an example of a combustion reaction?

Back

An example of a combustion reaction is the burning of propane: C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O.

Front

What type of reaction is represented by 2NO₂ → N₂ + 2O₂?

Back

This is a decomposition reaction.
