Question

based on the following balanced equation:
2h₂ + o₂ → 2h₂o
how many moles of h₂o form from 4 moles of o₂?
4 moles o₂ → ? moles h₂o

Explanation:

Step1: Analyze the mole ratio

From the balanced equation \(2H_2 + O_2
ightarrow2H_2O\), the mole ratio of \(O_2\) to \(H_2O\) is \(1:2\).

Step2: Calculate the moles of \(H_2O\)

If there are \(4\) moles of \(O_2\), using the ratio \(\frac{2\space mol\space H_2O}{1\space mol\space O_2}\), we have \(4\space mol\space O_2\times\frac{2\space mol\space H_2O}{1\space mol\space O_2}\).

Answer:

\(8\)
