Chemistry Lab: Types Of Chemical Reactions. The purpose of this lab is: 1) To observe some chemical reactions and identify reactants and products of those reactions. 2) To classify the reactions and write balanced equations. $

PURPOSE: To compare the experimental mass to the theoretical mass of a product of a chemical reaction. Given the mole relationships in a balanced chemical equation, and the mass of one of the reactants, it is possible to determine the number of moles of every other substance taking part in the reaction.

This is a set of 4 mini-labs that I use when teaching my unit on Matter and Change. Each mini-lab is a stand-alone activity, so you can choose to do all of them or just a few of them. Purpose of the labs: 1. To determine the density of pennies minted before 1982 and after 1982. 2. To use paper chromatography as a method of separating the components of a mixture. 3. To determine if a strange substance is a solid or a liquid. 4. To observe several chemical changes.
