<span>Answer:
Connect the atoms with single bonds. The less electronegative is the phosphorous atom. Hence, the P atom is going to be the central atom. Recall that electronegativity decreases as we move away from the fluorine atom in the periodic chart.

Answer:
V₂ = 70.80 L
Explanation:
Given data:
Initial volume of He = 45 L
Initial temperature = 250 °C
Final temperature = 550 °C
Final volume = ?
Solution:
Initial temperature = 250 °C (250+273.15 K= 523.15 K)
Final temperature = 550 °C (550 + 273.15 k= 823.15 K)
According to Charles Law.,
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 45 L × 823.15 K / 523.15 K
V₂ = 37041.75 L.K / 523.15 K
V₂ = 70.80 L
