Identifying Types of 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: 2H₂ + O₂ → 2H₂O.

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: 2H₂O → 2H₂ + O₂.

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: Zn + 2HCl → H₂ + ZnCl₂.

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: AgNO₃ + NaCl → AgCl + NaNO₃.

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.

Front

What is the general formula for a synthesis reaction?

Back

A + B → AB, where A and B are reactants that combine to form a product AB.

Front

What is the general formula for a decomposition reaction?

Back

AB → A + B, where AB is a compound that breaks down into its components A and B.

Front

What is the general formula for a single replacement reaction?

Back

A + BC → AC + B, where A replaces B in the compound BC.

Front

What is the general formula for a double replacement reaction?

Back

AB + CD → AD + CB, where the ions of two compounds exchange places.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
