Question

how many moles of kcl are produced at the same time as 9 moles o₂? 2kclo₃ → 2kcl + 3o₂

Explanation:

Step1: Analyze the mole ratio

From the balanced chemical equation \(2KClO_3
ightarrow2KCl + 3O_2\), the mole ratio of \(KCl\) to \(O_2\) is \(2:3\).

Step2: Set up the proportion

Let \(x\) be the moles of \(KCl\). Then \(\frac{x}{9}=\frac{2}{3}\).

Step3: Solve for \(x\)

Cross - multiply: \(3x = 2\times9\), so \(3x=18\), and \(x=\frac{18}{3}=6\).

Answer:

\(6\)
