Chapter 5 - Chemical Reactions

Terms

100

What is the definition of a product?

A substance that is produced by a chemical reaction

200

What is the definition of reactant?

A substance that is used up in a chemical reaction

300

Describe how the Law of Conservation of energy and matter are involved with balancing equations

Matter and energy cannot be created or destroyed, substances in reactants and products needs to be equal so balancing equations is neccessary

Describe the activity series

A list of elements that is organized from the most reactive element to the least reactive element
