1. The chemical equation for the formation of water is 2h2 + o2 →2h2o. rnrna. if 3.3 mol o2 are used, how many moles of h2 are needed?
Accepted Answer
A. If 3.3 mol O2 are used, the number of moles of H2 needed can be calculated using the stoichiometry of the balanced chemical equation:
2 moles of H2 react with 1 mole of O2
Therefore, 3.3 moles of O2 will react with (3.3 moles O2) * (2 moles H2 / 1 mole O2) = 6.6 moles H2
