Question

question 28 (1 point)
consider the reaction: 4fe(s) + 3o₂(g) → 2fe₂o₃(s). what is the stoichiometric ratio of moles of fe versus moles of fe₂o₃?
a) 3 mol: 2 mol
b) 4 mol: 1 mol
c) 4 mol: 2 mol
d) 2 mol: 4 mol

Explanation:

Step1: Analyze the balanced chemical equation

The balanced equation is \(4Fe(s)+3O_{2}(g)\to2Fe_{2}O_{3}(s)\).

Step2: Determine the stoichiometric coefficients

The coefficient of \(Fe\) is \(4\) and the coefficient of \(Fe_{2}O_{3}\) is \(2\).

Step3: Calculate the ratio

The ratio of moles of \(Fe\) to moles of \(Fe_{2}O_{3}\) is \(4:2\).

Answer:

C. \(4\space mol:2\space mol\)
