Interpretation:
The correct option for the limiting reactant and the number of moles of Fe3O4 formed in the given reaction needs to be identified when 16.8 g Fe is reacted 10.0 g of H2O.
Concept introduction:
A chemical equation is representation of a
Limiting reactant is defined as a reactant which limits the product formed in the reaction. This reactant actually decides the yield of the reaction.
Answer to Problem 20STP
The option (A) is correct.
Explanation of Solution
Below is the balance chemical equation:
Since,
Molar mass of Fe = 55.845 g/mol
Molar mass of H2O = 18 g/mol
Molar mass of Fe3O4 = 231.533 g/mol
16.8 g Fe
10.0 g of H2O
Here 3 moles of Fe and 4 moles of H2O combines to form 1 mole of Fe3O4.
Now, the amount of product formed from Fe and H2O is calculated as follows:
From Fe:
From H2O:
Here, limiting reagent is Fe since it yields less Fe3O4 compare to H2O. The H2O is in excess. The yield of Fe3O4 is 0.100 mol.
Therefore, option A is correct.
