of Fe is produced during the given experiment.
Further explanation:
The species or reagent in a chemical reaction that governs the amount of product is called the limiting reagent. It is completely consumed in the reaction.
Stoichiometry helps in determining the amount of species present in any reaction by establishing the relationship between reactants and products.
The balanced chemical reaction is as follows:
The reaction stoichiometry states that one mole of reacts with two moles of Al to produce one mole of and two moles of Fe.
We are provided with 3 moles of and 5 moles of Al. Therefore the amount of Fe produced by 3 moles of can be calculated as follows:
Similarly, the amount of Fe produced by 5 moles of Al can be calculated as follows:
Since Al produces less amount of Fe than that formed by , Al is a limiting reagent. It will decide the amount of Fe produced during the reaction. Therefore 5 moles of Fe moles formed in this reaction.
The formula to calculate the moles of Fe is as follows:
...... (1)
Rearrange equation (1) to calculate the mass of Fe.
...... (2)
Substitute 5 mol for the moles of Fe and 55.845 g/mol for the molar mass of Fe in equation (2).
