types of chemical reactions

Front

What is a chemical reaction?

Back

A process that involves the transformation of one or more substances into different substances, characterized by the breaking and forming of chemical bonds.

Front

What evidence indicates a chemical reaction has occurred?

Back

The production of a new substance is the best evidence of a chemical reaction.

Front

What is a compound?

Back

A substance formed when two or more elements chemically bond together, such as sodium chloride (NaCl).

Front

What is a combination reaction?

Back

A type of chemical reaction where two or more reactants combine to form a single product, represented by the general formula A + B → AB.

Front

What is a combustion reaction?

Back

A chemical reaction that occurs when a substance reacts with oxygen, producing heat and light, typically resulting in carbon dioxide and water.

Front

What is a single displacement reaction?

Back

A reaction where one element replaces another in a compound, represented by the general form A + BC → AC + B.

Front

What is a double displacement reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds, represented by the general form AB + CD → AD + CB.

Front

What is the general formula for a decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler substances, represented by the general form AB → A + B.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.

Front

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as a reactant that combines with the fuel (such as hydrocarbons) to produce energy, carbon dioxide, and water.
