Phosphine, PH₃, a reactive and poisonous compound, reacts with oxygen as follows: 4PH₃(g)+ 8O₂(g)→ P₄O₁₀(s)+ 6H₂O(g)If 9.2 moles of phosphine react with sufficient oxygen, how many moles of P₄O₁₀ should form?

Question

Quizplus · Accepted Answer

From the balanced equation, we can see that for every 4 moles of PH₃ that react, 1 mole of P₄O₁₀ is produced. Therefore, we can calculate the number of moles of P₄O₁₀ by dividing 9.2 moles of PH₃ by 4 and getting 2.3 moles of P₄O₁₀. So, the answer is D.
