Types of Chemical Reactions

Front

What is a synthesis reaction?

Back

A type of chemical reaction where two or more reactants combine to form one product.

Front

What is the law of conservation of mass?

Back

At the end of a chemical reaction, the total mass of the reactants is equal to the total mass of the products.

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 single replacement reaction?

Back

A type of chemical reaction where one element replaces another in a compound, represented by the formula A + CD → C + AD.

Front

What happens to atoms during a chemical reaction?

Back

Atoms are never lost or gained; they are just rearranged to form new substances.

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 decomposition reaction?

Back

A type of chemical reaction where one compound breaks down into two or more simpler substances.

Front

What is a double replacement reaction?

Back

A type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is an example of a synthesis reaction?

Back

The formation of water (H2O) from hydrogen (H2) and oxygen (O2) gases.

Front

What is an example of a decomposition reaction?

Back

The breakdown of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2).
