Phosphine, PH₃, a reactive and poisonous compound, reacts with oxygen as follows: 4PH₃(g)+ 8O₂(g)→ P₄O₁₀(s)+ 6H₂O(g)If you need to make 6.5 moles of P₄O₁₀, how many moles of PH₃ is required for the reaction?

Question

Quizplus · Accepted Answer

The balanced chemical equation shows that 4 moles of PH3 react to produce 1 mole of P4O10. Therefore, to produce 6.5 moles of P4O10, (4 moles PH3/1 mole P4O10) * 6.5 moles P4O10 = 26 moles of PH3 are required.
