Which of the following processes involves smelting
Which of the following processes involves smelting
Options
- A{\text{ZnCO}_{3} \to {\text{ZnO+CO}_{2}
- B{\text{Fe}_{2} {O}_{3} \text{+}\text{3C} \to \text{2Fe}\text{+}\text{3CO}
- C\text{2PbS}\text{+}{\text{3O}_{2} \to \text{2PbO}\text{+}{\text{2SO}_{2}
- D{\text{Al}_{2} {O}_{3} {\text{.2H}_{2} \text{O} \to {\text{Al}_{2} {O}_{3} \text{+}{\text{2H}_{2} \text{O}
Correct answer
B. {\text{Fe}_{2} {O}_{3} \text{+}\text{3C} \to \text{2Fe}\text{+}\text{3CO}
Step-by-step solution
Reduction with carbon is called smelting
{\text{Fe}_{2} {O}_{3} \text{+}\text{3C} \to \text{2Fe}\text{+}\text{3CO}
{\text{Fe}_{2} {O}_{3} \text{+}\text{3C} \to \text{2Fe}\text{+}\text{3CO}
