Chemical Reactions Test Review

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.

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 is a balanced chemical equation?

Back

An equation that has the same number of each type of atom on both sides, indicating that mass is conserved.

Front

What are reactants and products?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

What is a synthesis reaction?

Back

A type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

What is a decomposition reaction?

Back

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

Front

What is a single replacement reaction?

Back

A type of chemical reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

Front

What is combustion?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat.

Front

How do you balance a chemical equation?

Back

By adjusting the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.
