Flashcard 3 Types of 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: A + B → AB.

Front

What is a Decomposition Reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: 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 + 2O₂ → CO₂ + 2H₂O.
