Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

The Sequence of Chemical Reactions Drew Selfridge Dave Allen‚ Lab partner Instructor Yang February 11‚ 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form‚ but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process‚ however‚ some of the Cu+2 ions may be lost. The copper will subjected
