Chemistry Lab: Evidence of a Chemical Reaction

This is a great lab to use at the beginning of your chemical reactions unit. Students will perform six reactions and identify the evidence of a chemical change for each reaction. In the evidence of a chemical change lab students will perform reactions that will- Test the Law of Conservation of Mass Endothermic/Exothermic reactions Formation of a precipitate reaction Reactant replaced by the product, (single replacement reaction) Change in temperature (energy) ***THIS LAB IS INCLUDED IN THE FOLLOWING BUNDLE:*** Chemical Reactions Mega Unit Bundle Objectives: Observe reactions and state evidence that a chemical reaction has occurred Based on observations, make inferences about the products and the reaction. Prior Knowledge for Students: Students need to be able to write chemical formulas from chemical names prior to this lab. Students do NOT need to know the types of reactions prior to this lab.
