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: A + B → AB.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where parts of two compounds exchange places to form two new compounds. Example: AB + CD → CB + AD.

What happens to atoms during a chemical reaction?

Back

Atoms are never lost or gained; they are just rearranged to form new substances.

Front

What is the general formula for a synthesis reaction?

Back

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

What is the general formula for a double displacement reaction?

Back

The general formula for a double displacement reaction is AB + CD → CB + AD.

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 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 displacement reaction?

Back

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

Front

What is the difference between synthesis and decomposition reactions?

Back

In synthesis reactions, multiple reactants combine to form one product, while in decomposition reactions, one reactant breaks down into multiple products.

Front

What is the role of energy in chemical reactions?

Back

Energy is required to break bonds in reactants and is released when new bonds form in products.
