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. .

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

Explanation:

The given reaction is:

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

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
