Observations of Chemical Changes Page. 14 Objectives: The objectives of this experiment are: 1. To observe some properties of chemical reactions 2. to associate chemical properties with household products Background Information: Chemical changes are often accompanied by physical changes. Three that you should not see in this lab are changes in temperature‚ presence of a flame‚ and evolution of light‚ as when as firefly glows. Three physical changes that indicate a chemical change may have

Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light.
