One such reaction is a single replacement reaction, where an element in a compound is replaced by another element.**Reaction Representation:**\[ Fe_{(s)} + CuSO_4_{(aq)} \rightarrow FeSO_4_{(aq)} + Cu_{(s)} \]**Description:**This is a single replacement reaction where a solid iron (Fe) rod is placed in a solution of copper sulfate (CuSO₄). During the reaction, copper (Cu) will be deposited on the iron rod, and the solution will change from blue to green as FeSO₄ forms.**Visual Examination:**- **Left Test Tube:** - Contains a blue solution of copper sulfate (CuSO₄). - An iron rod (Fe) is submerged in the solution.- **Right Test Tube:** - The solution color has changed to green, indicating the formation of iron(II) sulfate (FeSO₄). - Copper (Cu) is now deposited on the iron rod.**Question:**What would you use to prove that copper is reduced in the following reaction?**Answer Choices:**A. A decrease in its oxidation number B. An increase in its oxidation number C. A gain of oxygen D. A loss of electrons **Explanation:**To determine whether copper is reduced, we need to analyze the changes in the oxidation states of copper. In its ionic form in copper sulfate (Cu²⁺), copper has an oxidation number of +2. When copper is deposited as a solid (Cu), it has an oxidation number of 0. A reduction in terms of redox reactions involves a decrease in the oxidation number.**Conclusion:**The correct answer to the question is:**A decrease in its oxidation number** (Option A).This visual illustrates how single replacement reactions involve the transfer of electrons, leading to observable changes in the physical state and coloration of the involved substances.

Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. ionization + F F + e + Bi → Bi + e + Te Te te energy required 1 (least) 3 (most) 2 ↑ ↑ ionization + PbPb + e + C1 → C1 + e + Sb Sb + e energy required X 3 (most) 1 (least) ↑ è 2 Ś ↑
