What volume of hydrogen gas, when combined with nitrogen gas,
Westkost [7]

The volume of Hydrogen gas : 24 L

<h3>Further explanation</h3>

Given

16 L Ammonia(NH₃)

Required

The volume of Hydrogen gas

Solution

Reaction

N₂ + 3H₂ ⇒ 2NH₃

Avogadro's hypothesis:  

In the same T,P and V, the gas contains the same number of molecules  

So the ratio of gas volume will be equal to the ratio of gas moles  

V₁/n₁=V₂/n₂

From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so volume of H₂ :

= 3/2 x volume of NH₃

= 3/2 x 16 L

= 24 L

KengaRu [80]

Answer:

<em>The correct option is B) Tropical rain forest</em>

Explanation:

The tropical rain forest biome acquires four main characteristics:

1: Increased amounts of rainfall in a year

2: high average temperatures

3: soil that is not enriched with nutrients

4: increased level of biodiversity.

Extreme levels of biodiversity can be seen in the tropical rain forest biome. Hence, due to increased biodiversity, this biome has multistory communities. This biome contains about 50% of the world's known animal and plant species.
