  • 11. 

    ONLY Place the coefficient in your answer___ P     + ____ O2   âž¥ ____ P2O5

    Correct Answer
    4 - 5 - 2
    Explanation
    The given equation represents the balanced chemical equation for the reaction between P and O2 to form P2O5. The coefficients in front of the chemical formulas represent the number of moles of each substance involved in the reaction. In this case, the coefficient for P is 4, indicating that 4 moles of P react. The coefficient for O2 is 5, indicating that 5 moles of O2 react. Finally, the coefficient for P2O5 is 2, indicating that 2 moles of P2O5 are formed.
