Web23 okt. 2015 · Explanation: Start by taking a look at the balanced chemical equation for this reaction 2H2 (g] +O2 (g] → 2H2O(l] Notice that you have a 2:1 mole ratio between hydrogen gas and oxygen gas. This means that, regardless of how many moles of oxygen gas you have, the reaction needs twice as many moles of hydrogen gas in order to proceed.
