Problem 5.8

Identify the oxidized reactant, the reduced reactant, the oxidizing agent, and the reducing agent in the following reactions:

(a) $$\mathrm{Fe}(s)+\mathrm{Cu}^{2+}(a q) \longrightarrow \mathrm{Fe}^{2+}(a q)+\mathrm{Cu}(s)$$

(b) $$\mathrm{Mg}(s)+\mathrm{Cl}_{2}(g) \longrightarrow \mathrm{MgCl}_{2}(s)$$

(c) $$2 \mathrm{Al}(s)+\mathrm{Cr}_{2} \mathrm{O}_{3}(s) \longrightarrow 2 \mathrm{Cr}(s)+\mathrm{Al}_{2} \mathrm{O}_{3}(s)$$

Chemistry notes week 1 Underlined= main topic Highlighted= vocabulary Highlighted= important name Bold= important to remember about the topic  Chemistry- the study of matter and the changes in matter  The changes in matter often include these two:  Physical change- A change in matter that does not include changing the chemical composition of the object  Ex. Ripping a piece of paper is a physical change because the chemical composition did not change  Chemical change- a change in matter where the chemical composition is changed after the reaction is complete  Ex. Burning a piece of paper is a chemical change because the paper has become ash and gas  Rusting, burning, and a production of gas are all good signals that a chemical change in occurring  The Scientific Method  Steps:  1. Make an observation  2. Make a prediction/ form a hypothesis, or a guess as to why something happens  3. Test the hypothesis through experimentation  4. Revise or throw out the hypothesis depending on how successful it was  5. Test the revised hypothesis  The scientific method could lead to two things:  Theory- an extensively tested hypothesis that continues to be proved true  The Atom Theory- everything is made of atoms  This theory has been extensively tested and backed up with evidence  Law- Observation that proves to be true by continuous observations
