Question

11 fill in the blank 1 point balance the following chemical equation: type your answer... p + type your answer... o₂ ---> type your answer... p₂o₅ include the 1s if necessary.

Explanation:

Step1: Balance phosphorus atoms

Count P on right: 2 in $\text{P}_2\text{O}_5$. Add coefficient 2 to left P:
$2\text{P} + \text{O}_2
ightarrow \text{P}_2\text{O}_5$

Step2: Balance oxygen atoms

Count O on right: 5 in $\text{P}_2\text{O}_5$. Use $\frac{5}{2}$ for $\text{O}_2$:
$2\text{P} + \frac{5}{2}\text{O}_2
ightarrow \text{P}_2\text{O}_5$

Step3: Eliminate fractional coefficient

Multiply all terms by 2:
$4\text{P} + 5\text{O}_2
ightarrow 2\text{P}_2\text{O}_5$

Step4: Verify atom counts

Left: 4 P, 10 O; Right: 4 P, 10 O. Balanced.

Answer:

4, 5, 2
