Sample questions

1. 1.What process is used to remove impurities from iron obtained from the blast furnace?
   • A.Reduction
   • B.Oxidation
   • C.Electrolysis
   • D.Distillation
2. 2.Compare the properties of metals and non-metals on the basis of the type of oxides they form. Which of the following statements is correct?
   • A.Metals form acidic oxides, while non-metals form basic oxides.
   • B.Metals form basic oxides, while non-metals form acidic or neutral oxides.
   • C.Both metals and non-metals form only neutral oxides.
   • D.Metals form oxides that react only with bases, while non-metals form oxides that react only with acids.
3. 3.Some metallic oxides can be reduced by hydrogen, carbon and carbon monoxide and some cannot. Why?
   • A.Metallic oxides of less reactive metals can be reduced by these agents due to their lower affinity for oxygen.
   • B.All metallic oxides can be reduced by hydrogen, carbon, or carbon monoxide regardless of reactivity.
   • C.Highly reactive metals form unstable oxides that are easily reduced by these agents.
   • D.The reducibility depends solely on the physical state of the oxide, not the metal's reactivity.
4. 4.Match the metals with their respective methods of refining:

   Metals	Method of Refining
   Zinc
   Lead and Tin
   Iron
   Copper, Zinc

5. 5.Iron reacts with steam to form Magnetic oxide of Iron and Hydrogen. Which of the following is the balanced chemical equation for this reaction?
   • A.Fe + H₂O → Fe₃O₄ + H₂
   • B.3 Fe + 4 H₂O → Fe₃O₄ + 4 H₂
   • C.2 Fe + 3 H₂O → Fe₂O₃ + 3 H₂
   • D.Fe + 2 H₂O → FeO₂ + 2 H₂
