Here are the answers to your questions: i) Give the reason why the electron configuration of copper is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^1 and not 1s^2 2s^2 2p^6 3s^2 3p^6 3d^9 4s^2. Step 1: Identify the principle of stability. The electron configuration 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^1 is preferred because a fully filled 3d^10 subshell is more stable than a partially filled 3d^9 subshell. Step 2: Explain the electron promotion. One electron from the 4s orbital is promoted to the 3d orbital to achieve this more stable, fully filled 3d^10 configuration. ii) Mention the two oxidation states of iron in its chlorides. Step 1: Identify common iron chlorides. Iron forms two common chlorides: iron(II) chloride (FeCl_2) and iron(III) chloride (FeCl_3). Step 2: Determine the oxidation states. In FeCl_2, the oxidation state of iron is +2. In FeCl_3, the oxidation state of iron is +3. The two oxidation states are +2 and +3. iii) Name one chemical process in which iron is used as a catalyst. Step 1: Recall industrial processes using iron as a catalyst. Iron is used as a catalyst in the Haber process. The chemical process is the Haber process. Send me the next one 📸
