Question

In the reaction \( 2 \, \text{H}_2 + \text{O}_2 \rightarrow 2 \, \text{H}_2\text{O} \), how many moles of water are produced when 4 moles of hydrogen react with excess oxygen?

• A. \( 2 \, \text{mol} \)
• B. \( 4 \, \text{mol} \)
• C. \( 6 \, \text{mol} \)
• D. \( 8 \, \text{mol} \)

Hint:

In stoichiometry, always pay attention to the molar ratios from the balanced chemical equation to determine how many moles of product will be produced from a given amount of reactant.
