H. Nitrogen gas and hydrogen gas combine to produce ammonia gas (NH3).

DedPeter [7]

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
