The chemical processes in the production of steel from haematite ore involve :
Correct answer: D. Oxidation followed by reduction
- A. Reduction
- B. Oxidation
- C. Reduction followed by oxidation
- D. Oxidation followed by reduction
Explanation
Oxidation followed by Reduction: This process involves the oxidation of carbon to carbon dioxide, followed by reduction steps to extract iron from haematite ore. The initial oxidation step generates heat and carbon dioxide, while the subsequent reduction reactions convert iron oxide to metallic iron, which is the desired product for steel production. The other options are incorrect because they do not follow the correct sequence of processes involved in steel production from haematite ore.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
