A sample of nitrogen gas reacts with an excess of hydrogen gas to give an actual yield of 22.8 g NH3. The theoretical yield is 26 g. What is the percent yield for this reaction? Reaction: N2(g) + 3 H2 (g) → 2 NH3 (g)

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.
