Reaction
a) CaCO3→CaO + CO2
b) CO2 + C → 2CO
c) Fe2O3 + 3CO → 2Fe + 3CO2
mol CaCO₃ (MW=100,0869 g/mol) :
mol CO₂ = mol CaCO₃ =13.39(reaction a)
mol CO = 2 x mol CO₂ = 26.78(reaction b)
mol CO(reaction c) = 1.5 mol CO from reaction b = 1.5 x 26.78 = 40.17
mol Fe(reaction c) = 2/3 x mol CO =
Or we can cancel out the same compound in different sides from the sum of the three reactions to find mol Fe
a) CaCO3→CaO + CO2
b) CO2 + C → 2CO
c) Fe2O3 + 3CO → 2Fe + 3CO2
----------------------------------------------+
CaCO3 + Fe2O3 + C + CO + 3CO2 ⇒ CaO + 2Fe
mol Fe = 2 x mol CaCO3 = 2 x 13.39 = 26.78
mass Fe :

Explanation:
Mecury vapor lamp is better to use than Sodium vapor light, this is because because
---The Filaments of the lamp in sodium emit fast moving electrons, which causes valence electrons of the sodium atoms to excite to higher energy levels which when electrons after being excited, relax by emitting yellow light which concentrates on the the monochromatic bright yellow part of the visible spectrum which is about 580-590 or about (589nm) which will fall incident on the calibrations making it difficult to see
While
In Mercury vapor lamp, The emitted electrons from the filaments, after having been excited by high voltage, hit the mercury atoms but the excited electrons of mercury atoms relax and emits an ultraviolet uv invisible lights falling on the mecury vapour lamp to produce white light covering a wide range of (380-780 nm) which is visible that is why it is used for calibrations purposes in lightening applications.
