based on the following balanced equation: 4fe + 3o₂ → 2fe₂o₃ how many moles of fe₂o₃ form from 8 moles of fe? 8 moles fe → ? moles fe₂o₃
Answer
Answer:
4
Explanation:
Step1: Identify mole - ratio
From the equation $4Fe + 3O_2\rightarrow2Fe_2O_3$, the mole - ratio of $Fe$ to $Fe_2O_3$ is $4:2$ or $2:1$.
Step2: Set up proportion
Let $x$ be the moles of $Fe_2O_3$. We have the proportion $\frac{4}{2}=\frac{8}{x}$.
Step3: Solve for $x$
Cross - multiply: $4x = 2\times8$. Then $4x=16$, and $x = 4$.
