Answer;
The ratio is 1:3
Explanation;
The formation of ammonia (NH3) from hydrogen (H2) and nitrogen (N2) gases according to the equation;
N2 + 3H2 → 2NH3
Molecules of hydrogen react with molecules of nitrogen in the ratio 3:1.
In other words, 1 molecule of ammonia consists of 1 atom of nitrogen (N) and 3 atoms of hydrogen (H). Basically, for ammonia the ratio of nitrogen atoms to hydrgen atoms (N:H) is always 1:3.
