If 5.02 moles of iron react with excess oxygen gas, how many moles of Fe2O3 can be produced?

The answer to your question is 2.51 moles of Fe₂O₃ will be formed.

Explanation:

Data

Moles of Fe = 5.02

O₂ = excess

Moles of Fe₂O₃ = ?

Process

1.- Write the balanced chemical reaction

                   4Fe  +  3O₂   ⇒    2Fe₂O₃

            Reactants    Elements   Products

                   4                Fe                4

                   6                O                 6

2.- Calculate the moles of Fe₂O₃ when react 5.02 moles of Fe using proportions.

                      4 moles of Fe 2 moles of Fe₂O₃

                      5.02 moles     x

                      x = (5.02 x 2) / 4

                      x = 10.04/4

                     x = 2.51 moles

the answer is c

tell me if wrong

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
