Which combination of molecules will produce ammonia with no leftovers?
A.8N2 and 4H2

B.5N2 and 6H2

C. 4N2 and 4H2

D. 2N2 and 6H2

Answer 1

The combination that will produce ammonia with no leftovers is; 2N2 and 6H2

The equation of the reaction must be kept in mind;

N2 + 3H2 → 2NH3

We can see that it takes the reaction of 1 mole of ammonia and 3 moles of hydrogen to form ammonia.

This means that the molar ratio of nitrogen to hydrogen is 1:3

The option that correctly fits this mole ratio is  D:  2N2 and 6H2.
