level questions: Extracting Metals from their Ores
| Question | Answer |
|---|---|
| What is a Metal Ore? What is an Ore usually Compromised of | -This is simply a Rock with has enough Metal to make it Worth While to Extract it. -It is usually an Oxide of the Metal - Aluminium Ore is called Bauxite [AL₂ O₃] |
| How can a Metal be Extracted from its Ore? | -This can be done Chemically [Reduction] or Electrolysis -And also using Displacement Reactions or Biological Methods |
| How can a Metal be Extracted from its Ore via the Element: Carbon? | -This is simply a Redox Reaction, as Carbon gets Oxidised [Gets Oxygen] and the Metal Oxide gets Reduced [Loses Oxygen] |
| What happens to Copper Oxide in this Reaction? 2CuO + C --> 2Cu + CO₂ | -Copper Oxide here gets Reduced into just Copper. That's it |
| List the Reactivity Series, that also includes Carbon | -Potassium [K] Most Reactive -Sodium [Na] -Calcium [Ca] -Magnesium [Mg] -Aluminium [Al] -Carbon [C] -Zinc [Zn] -Iron [Fe] -Tin [Sn] -Copper [Cu] Least Reactive |
| What does Carbons Place in the Reactivity Series say about how you can Extract a Metal from its Ore? | -The Metals that are below Carbon in the Reactivity Series means Reduction [Involving Carbon] can Take Place -The Metals that are above Carbon in the Reactivity Series means it needs Electrolysis to be Extracted. This is Expensive |
