What are reactants in a chemical equation?

Back

Substances that undergo a chemical change during a reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

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

Front

What does it mean to balance a chemical equation?

Back

To ensure that the number of atoms of each element is the same on both sides of the equation.

Front

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound, represented as A + BC → B + AC.

Front

What is a double replacement reaction?

Back

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

Front

What is a synthesis reaction?

Back

A reaction where two or more reactants combine to form a single product, represented as A + B → AB.

Front

What is a decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products, represented as AB → A + B.

Front

What is combustion?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing heat and light.
