Question

The balanced chemical equation, 2NO (g) + 5H2 (g) (Arrow pointing this way >>) 2NH3 (g) + 2H2O (g), can be expressed in words as:
Nitrogen dioxide gas plus hydrogen gas yields ammonia gas plus water

Nitrogen monoxide gas plus hydrogen gas yields ammonia gas plus water vapor

Nickel monoxide gas plus hydrogen gas yields nitrogen trihydride plus water

Nitrogen oxide gas plus hydrogen gas yields ammonia gas plus water vapor

I think it's either B, or D. I can't figure out which one it is though. Please help.

Answer 1

Answer:

B) Nitrogen monoxide gas plus hydrogen gas yields ammonia gas plus water vapor

Explanation:

The given reaction is:

$2NO(g) + 5H_{2}(g)\rightarrow 2NH_{3}(g)+ 2H_{2}O(g)$

Here the chemical names of the reactants are:

NO = nitric oxide or nitrogen monoxide in gas phase

H2 = hydrogen gas

NH3 = ammonia in gas phase

H2O = water in gas phase i.e. vapor

Therefore the reaction can be expressed in words as:

Nitrogen monoxide gas plus hydrogen gas yields ammonia gas plus water vapor

Answer 2

Both B AND D are correct and same
