Chemical reaction classification

Front

What is a chemical reaction?

Back

A process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

What are the main types of chemical reactions?

Back

1. Synthesis (Combination) 2. Decomposition 3. Single Replacement 4. Double Replacement 5. Combustion

Front

Define a synthesis reaction.

Back

A reaction where two or more reactants combine to form a single product. Example: A + B → AB.

Front

Define a decomposition reaction.

Back

A 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 reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a double replacement reaction?

Back

A reaction where the anions and cations of two different compounds exchange places to form two new compounds. Example: AB + CD → AD + CB.

Front

What is a redox reaction?

Back

A reaction involving the transfer of electrons between two species, resulting in changes in oxidation states.

Front

What is oxidation in a redox reaction?

Back

The process of losing electrons, resulting in an increase in oxidation state.

Front

What is reduction in a redox reaction?

Back

The process of gaining electrons, resulting in a decrease in oxidation state.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.
