Answer: B. 4 moles Fe and 3 moles CO2
Explanation:
write a balanced chemical reaction
that is FeO3 + 3 CO → 2 Fe + 3CO2
2 moles of Fe2O3 reacted with 3 x2=6 moles of Co to form Fe and CO2 therefore CO was in excess and Fe2O3 was limiting reagent.
use the mole ratio to determine the moles of each product.
that is the mole ratio 0f Fe2O3 : Fe is 1:2 therefore the moles of Fe = 2x2=4 moles
the mole ratio of Fe2CO3 : CO2 is 1: 3 therefore the moles of Co2 = 2 x3 = 6 moles
If 2 moles of Fe2O3 react with 9 moles of CO, moles of each product is formed will be 6 moles.
What is a mole?
A standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, etc, is referred to as mole.
According to the given scenario, the first one should create a chemical reaction that is balanced
FeO3 + 3 CO 2 Fe + 3CO2 is the formula.
Because 2 moles of Fe2O3 reacted with 3 x2=6 moles of Co to produce Fe and CO2, CO was in excess and Fe2O3 was the limiting reagent.
To calculate the moles of each product, use the mole ratio.
That is the Fe2O3 mole ratio: Because Fe is a 1:2 element, the mole of Fe is 2x2=4 moles.
Because the mole ratio of Fe2CO3 to CO2 is 1:3, the moles of Co2 are 2 x 3 = 6 moles.
Thus, If 2 moles of Fe2O3 react with 9 moles of CO, moles of each product is formed will be 6 moles.
