Question

15. How do you know a chemical reaction has occured? (remember GOTPC) 16. This reaction is classified as a single replacement reaction. Why? 17. After the chemical reaction, there is a brownish substance floating in the solution. What is it? \begin{tabular}{|c|l|l|} \hline \multicolumn{3}{|c|}{ How MANY of each type of atom appears on each side of the chemical equation? } \\ \hline Atom & Reactant side & Product side \\ \hline Aluminum & & \\ \hline Copper & & \\ \hline Chlorine & & \\ \hline \end{tabular} 18. What do all these chemical reactions have in common? 19. How is the Law of Conservation of Matter demonstrated in these reactions?
