Worked practice questions

As per your syllabus, a COMBINATION reaction is classified as redox under which condition?

  1. Both reactants are compounds
  2. No condition needed
  3. One product is a salt
  4. At least one reactant is an element
Show answer and solution

Correct answer: D. At least one reactant is an element

Your syllabus: A + B → C is redox if A or B (or both) is in elemental form (which has ox. no. 0).

As per your syllabus, the decomposition CaCO₃(s) → CaO(s) + CO₂(g) is classified as which kind of reaction?

  1. A disproportionation
  2. Not a redox
  3. A combination redox
  4. A displacement redox
Show answer and solution

Correct answer: B. Not a redox

Your syllabus: all ox. numbers stay the same (Ca +2, C +4, O −2). Not all decompositions are redox.

As per your syllabus, eqn 7.32, the reaction Cr₂O₃(s) + 2 Al(s) → Al₂O₃(s) + 2 Cr(s) is an example of which industrial method?

  1. Aluminothermite
  2. Hall-Héroult process
  3. Electrolysis
  4. Bessemer process
Show answer and solution

Correct answer: A. Aluminothermite

Your syllabus: aluminothermic reduction — Al displaces Cr/Ti/V from their oxides for metal extraction.
