Classes of Chemical Reactions Whenever a reaction takes place‚ energy is changed as well when the substances react chemically. Scientists have taken these changes in energy and generalized them. Scientists can take these generalizations and discover more about the nature and tendencies of matter. In this lab‚ the purpose was to perform seven reactions‚ write down their equations‚ and identify the type of reaction. In this lab report‚ several methods of displaying this information will be applied
