Oxidation
Reduction
Electrolysis
Fractional distillation
Answer is Right!
Answer is Wrong!
The correct answer is B. Reduction.
Iron ore is a mineral that contains iron. It is the primary raw material used to make iron and steel.
Iron ore is mined from the earth and then processed to remove impurities. The most common type of iron ore is hematite, which is a red ore.The manufacturing of iron from iron ore involves the process of reduction. Reduction is a chemical reaction in which an element or compound loses oxygen. In the case of iron ore, the iron is reduced from its oxide form to its metallic form. This is done by heating the iron ore with a reducing agent, such as coke or charcoal. The reducing agent removes the oxygen from the iron ore, leaving behind molten iron.
The other options are incorrect.
- Option A, oxidation, is the opposite of reduction. Oxidation is a chemical reaction in which an element or compound gains oxygen.
- Option C, electrolysis, is a process that uses electricity to separate elements from a compound.
- Option D, fractional distillation, is a process that separates liquids based on their boiling points.
