*explain answer for brainliest
Which of the following is a valid mole ratio from the balanced equation 2Fe2O3 + 3C → 4Fe + 3CO2?
two moles of F e two O three over four moles of F e
four moles of C over three moles of F e
two moles of F e two O three over four moles of C
three moles of C over four moles of C O two

Answer 1

Answer:

2 mol Fe₂O₃/ 4 mol Fe  

Step-by-step explanation:

The balanced equation is

2Fe₂O₃ + 3C → 4Fe + 3CO₂

The molar ratio uses the coefficients of the formulas in the balanced equation.

Those in front of Fe₂O₃  and Fe are 2 and 4, respectively.

B is wrong. the correct ratio is 3 mol C/4 mol Fe.

C is wrong. The correct ratio is 2 mol Fe₂O₃/3 mol C.

D is wrong. The correct ratio is 3 mol C/3 mol CO₂.

Answer 2

Answer:

2 mol Fe2O3/ 4 mol Fe is the correct answer.
