Question

Consider the following chemical reaction :
aFe2O3(s) + bCO(g) + cFe(s) + dCO2
In the balanced chemical equation of the above, which of the following will be the values of the coefficients a, b, c and d respectively?
A) 3, 2, 3, 1 B) 1, 3, 2, 3 C) 2, 3, 3, 1 D) 3, 3, 2, 1

Answer 1

Answer:

Fe2O3 + 3CO = 2Fe + 3CO2

Hematite + Carbon Monoxide = Iron + Carbon Dioxide

In this reaction, the iron oxide is reduced to iron, and the carbon is oxidised to carbon dioxide
