based on the following balanced equation: 4al + 3o₂ → 2al₂o₃ how many moles of al₂o₃ form from 12 moles of al? 12 moles al → ? moles al₂o₃
Answer
Explanation:
Step1: Identify mole - ratio
From the balanced equation $4Al + 3O_2\rightarrow2Al_2O_3$, the mole - ratio of $Al$ to $Al_2O_3$ is $4:2$ or $2:1$.
Step2: Set up proportion
Let $x$ be the number of moles of $Al_2O_3$. We have the proportion $\frac{2}{1}=\frac{12}{x}$.
Step3: Solve for $x$
Cross - multiply: $2x = 12\times1$. Then $x=\frac{12\times1}{2}=6$.
