Which statement justifies that phosphine (PH3) is a polar molecule?

1 answer:

4 0

The P-H bond is polar and the molecule is asymmetric.

Non-polar bonds cannot produce polar molecules and symmetric bonds result in even distribution of charge, so no net charge is observed.

Answer:

27.3 L

Explanation:

Reaction

N₂ (g) + 3H₂ (g) ⇒ 2NH₃ (g)
This is the basic reaction at STP

Solving

10 g N₂ x 1 mol NH₃/28 g N₂ x 3 mol H₂/1 mole N₂
⇒ 1.07 mol H₂

V = nRT/P [From Ideal Gas Equation]
V = 1.07 x 62.36 x 298 K / 735
V = 27.3 L
