This week we completed another lab relating to chemical reactions and their equations. In this lab, we reacted we metals with water, hydrochloric acid, silver nitrate and copper sulfate and determined if a chemical reaction had occurred. The four major signs that a reaction has taken place are a change in color, formation of bubbles, heat and / or flame is produced or a solid is formed. This lab helped me visualizes all the rules and reactions we have been studying and also aided in preparation for the test.
