Extraction Using Heat

The video tutorial explains the production of iron from iron ore, focusing on the reactivity series of metals and the role of carbon in the reduction process. It details the formation of iron oxide and the historical shift from charcoal to coke as a carbon source. The tutorial describes the three-step reduction process involving carbon dioxide and carbon monoxide, classifying it as a redox reaction. It also covers the concept of electron transfer in redox reactions and compares the extraction of iron and copper, highlighting the reactivity series.

What was the primary source of carbon for iron production before the industrial revolution?

• Coal

• Coke

• Charcoal

• Wood

Which of the following is NOT a role of carbon in the iron extraction process?

• Oxidizing agent

• Reducing agent

• Temperature supplier

• Fuel

In the reduction of iron oxide, what is the final product formed?

• Iron

• Carbon monoxide

• Iron oxide

• Carbon dioxide

What does the mnemonic 'OIL RIG' stand for in redox reactions?

• Oxidation is gain, Reduction is loss

• Oxidation is loss, Reduction is gain

• Oxidation is light, Reduction is gas

• Oxidation involves light, Reduction involves gas

Why was copper extraction discovered before iron extraction?

• Copper is more abundant than iron

• Copper is found in purer forms

• Copper is less reactive than iron

• Copper requires higher temperatures for extraction
