Concept explainers
Interpretation:
The moles of Fe have to be calculated.
Concept introduction:
Mole: The mole is the unit which is used to measure the amount of a substance. A mole can be defined as the number of carbon atoms which is present in exactly 12 g of pure carbon-12. A mole contains 6.023 × 1023 representative particles.
Stoichiometry: It can be defined as a study of quantitative relationships between the amounts of reactants used and amounts of products formed by a
Answer to Problem 8STP
Answer is C. 12 moles of Fe will be produced when 16 moles of H2 are used.
Explanation of Solution
From the above balanced chemical equation, it can bestated that one mole of iron(III) oxide reacts with four moles of hydrogen to produce three moles of iron and four moles of water.
3 moles of iron is produced from 4 moles of hydrogen.
So, 16 moles of hydrogen can produce =
Reasons for incorrect options:
From the calculation, 12 moles of Fe will be produced when 16 moles of H2 are used.
So, 16 moles of hydrogen can produce =
The correct answer is C.
That means other options that is,
A. 6
B. 3
D. 9 are found to be incorrect.
