Question

When the equation: __Fe2O3(s) + __CO(g) → __Fe(l) + __CO2(g) is correctly balanced using the smallest whole numbers, the coefficient of Fe(l) is

Answer 1

Answer: The coefficient of Fe(l) is 2

Explanation:

Balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.

The balanced chemical equation for the given reaction follows:

$Fe_2O_3(s)+3CO(g)\rightarrow 2Fe(l)+3CO_2(g)$

By Stoichiometry of the reaction:

1 mole of iron (III) oxide reacts with 3 moles of carbon monoxide to produce 2 moles of iron metal and 3 moles of carbon dioxide.

Hence, the coefficient of Fe(l) is 2

Answer 2

Fe2O3+3CO= 2Fe +3CO2 is the balanced equation
