Question

4P +502 → 2P2O5

What is the ratio of phosphorous to
oxygen in the reaction?
A. 1 P: 102
B. 1 P: 1.25 02
C. 1.25 P: 10₂
D. 5 P: 402

Answer 1

Answer: The ratio is option (b) 1P:1.25O2

Step-by-step explanation:

To determine the ratio of phosphorous (P) to oxygen (O) in the reaction, we have to compare the coefficients in front of each element in the balanced chemical equation.

4 P + 5 O2 → 2 P2O5

From the equation, we can observe that for every 4 moles of phosphorous (P) and 5 moles of oxygen (O2), we have 2 moles of P2O5

The ratio of phosphorous to oxygen is 4:5.

Now for one mole of Phosphorus, the equation will be

1 P + 1.25 O2 → 0.5 P2O5

Hence, the ratio of phosphorous to oxygen is 1P:1.25O2 which is option (B)

Answer 2

To determine the ratio of phosphorous (P) to oxygen (O) in the reaction, we can compare the coefficients in front of each element in the balanced chemical equation.

The balanced equation is: 4P + 5O2 → 2P2O5

From the equation, we can see that for every 4 moles of phosphorous (P), we have 2 moles of P2O5 (which contains 5 moles of oxygen).

Therefore, the ratio of phosphorous to oxygen is 4:5.

None of the provided options match this ratio exactly. However, option B comes closest with a ratio of 1 P: 1.25 O2.
