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. General formula: 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. General formula: 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. General formula: 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. General formula: 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 and heat. General formula: Hydrocarbon + O₂ → CO₂ + H₂O.

In a chemical reaction, what are Reactants?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

In a chemical reaction, what are Products?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is the general formula for a Combustion Reaction involving a hydrocarbon?

Back

The general formula is: Hydrocarbon + O₂ → CO₂ + H₂O.

Front

What is the difference between a Synthesis and a Decomposition Reaction?

Back

A synthesis reaction combines multiple reactants to form one product, while a decomposition reaction breaks down one compound into multiple products.

Front

What is an example of a Double Replacement Reaction?

Back

An example is: NaCl + AgNO₃ → NaNO₃ + AgCl.
