Question

Which is the next logical step in balancing the given equation? 3CO(g) + Fe2O3(s) Fe(s) + 3CO2(g)

Answer 1

Answer:- Next logical step is to balance Fe.

Explanations:- A balanced equation has equal number of atoms of each element. Looking at the given equation, there are three C and six O on both sides. Left side has two Fe where as the right side has just one Fe. It means Fe is not balanced. So, the next logical step is to balance Fe by placing two before Fe on right side and the balanced equation becomes:

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