Consider the chemical equation shown below.How many moles of oxygen gas are needed to react with hydrogen to form one mole of water? 2H₂(g)+ O₂(g)→ 2H₂O(l)

Question

Quizplus · Accepted Answer

The balanced chemical equation for the formation of water from hydrogen and oxygen is $2H_2(g) + O_2(g) \rightarrow 2H_2O(l)$. This shows that 1 mole of $O_2$ is needed to react with 2 moles of $H_2$ to produce 2 moles of $H_2O$. Therefore, to produce 1 mole of $H_2O$, 0.5 mole of $O_2$ is needed.
