Question

In the reaction \( 2 \, \text{H}_2 + \text{O}_2 \to 2 \, \text{H}_2\text{O} \), if 4 moles of hydrogen react completely with oxygen, how many moles of water will be produced?

• A. \( 2 \, \text{mol} \)
• B. \( 8 \, \text{mol} \)
• C. \( 4 \, \text{mol} \)
• D. \( 1 \, \text{mol} \)

Hint:

In stoichiometry problems, always refer to the balanced equation to use the mole ratio between reactants and products.
