1. Journal #14 Write the formula equation for the following reaction: Hydrogen gas reacts with chloride gas to form hydrochloric acid gas.

3. Pre-Lab You will identify the products formed in these reactions and summarize the chemical changes. You will observe changes in the chemicals to determine if a chemical reaction has occurred. You will record the temperature of the reactants and products to determine if the reaction is endothermic or exothermic You will record the mass of both the reactants and the products to determine the law of conservation of mass has been satisfied.

4. Pre-Lab You will perform 3 reactions: Hydrochloric acid and calcium carbonate Lead nitrate and potassium iodide Magnesium and hydrochloric acid Remember to pour the acid into the other reaction (Add Acid) Clean thermometer between measurements Have stations checked before leaving Work quickly and efficiently!!

5. Safety Precautions Wear safety goggles Check and clean all lab equipment before use Careful with acids Notify teacher of spills or accidents Clean up lab stations No horseplay
