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 reactants combine to form a single 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 element in a compound. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

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 a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction. It is present at the start of the reaction.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction. It is present at the end of the reaction.

Front

What is the general equation for a decomposition reaction?

Back

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

Front

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as a reactant in combustion reactions, combining with the fuel to produce energy, carbon dioxide, and water.

Front

What is the difference between a reactant and a product?

Back

A reactant is a starting material in a chemical reaction, while a product is a substance formed as a result of the reaction.
