Question

If 75 moles of Aluminum Oxide were produced, how many moles of solid Iron were produced?

a) 37.5 moles
b) 75 moles
c) 150 moles
d) 225 moles

Answer 1

For every mole of Aluminum Oxide produced, 2 moles of solid Iron are produced according to the balanced chemical equation. Therefore, if 75 moles of Aluminum Oxide were produced, 150 moles of solid Iron would be produced.

Step-by-step explanation:

To solve this problem, we must first understand the balanced chemical equation for the reaction between solid aluminum (Al) and iron (III) oxide (Fe₂O₃) to produce aluminum oxide (Al₂O₃) and solid iron (Fe). The balanced equation is:

2Al + Fe₂O₃ → Al₂O₃ + 2Fe

According to this equation, for every mole of Al₂O₃ produced, 2 moles of Fe are produced. Thus, if 75 moles of Aluminum Oxide were produced, then the amount of solid Iron produced would be 2 times that amount, which is 150 moles. Therefore, the correct answer to the question is 150 moles.
