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

Front

What is a balanced chemical equation?

Back

An equation where the number of atoms for each element is the same on both sides, indicating that mass is conserved.

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.

Front

What are reactants in a chemical reaction?

Back

Substances that undergo change during a chemical reaction.

Front

What are products in a chemical reaction?

Back

Substances that are formed as a result of a chemical reaction.

Front

What is a synthesis reaction?

Back

A type of reaction where two or more reactants combine to form a single product.

Front

What is a decomposition reaction?

Back

A type of reaction where a single compound breaks down into two or more simpler products.

Front

What is a single displacement reaction?

Back

A reaction where one element replaces another element in a compound.

Front

What is a double displacement reaction?

Back

A reaction where the ions of two compounds exchange places in an aqueous solution.

Front

What is a coefficient in a chemical equation?

Back

A large number placed in front of a chemical formula to indicate the number of molecules or moles of that substance.
