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.

Front

Define a Synthesis Reaction.

Back

A type of 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

Define a Single Replacement Reaction.

Back

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

Front

Define 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 Combustion Reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: C + O2 → CO2.

Front

Balance the equation: _Mg + _Cl2 → _MgCl2

Back

Already balanced (1, 1, 1).
