Which of the following is a valid mole ratio from the balanced equation 2Fe2O3+3C yield 4Fe+3CO2

riadik2000 [5.3K]

Answer :

The balanced chemical reaction is,

$2Fe_2O_3+3C\rightarrow 4Fe+3CO_2$

From this balanced chemical reaction, we conclude that

2 moles of iron oxide react with the 3 moles of carbon to give 4 moles of iron and 3 moles of carbon dioxide.

Therefore, the valid mole ratio from the balanced chemical reaction is,

$Fe_2O_3:C:Fe:CO_2=2:3:4:3$
