Essential Formulas & Mathematical Definitions
Roasting: 2ZnS + 3O₂ → 2ZnO + 2SO₂
Calcination: ZnCO₃ → ZnO + CO₂
Thermite: Fe₂O₃ + 2Al → 2Fe + Al₂O₃ + Heat
Extraction of Metals (Metallurgy)
Concentration of ore → Roasting (sulphides in excess air) or Calcination (carbonates in limited air) → Reduction with Carbon/Aluminium → Electrolytic Refining.

High-Yield Exam Strategy & Scoring Tips
Step-by-Step Mark Allocation
Always state the governing principle or formula first, write given values with standard SI units, substitute clearly, and highlight the final numerical answer with units in a box for full step marking.
Common Calculation Traps
Watch for unit prefixes (cm to m, minutes to seconds, g to kg, degrees to radians). In coordinate and ray optics problems, double-check Cartesian sign conventions before computing.
