Joyce combines 9 atoms of hydrogen and 3 atoms of nitrogen to make 3 molecules of ammonia.
Write a direcand t variation equation that relates atoms of hydrogen, H, to atoms of nitrogen, N how many nitrogen atoms does Joyce need to form ammonia molecules using 51 hydrogen atoms.
I've seen this question and I was curious who can figure it out. I'm new here so can anyone tell me how this work thanks.

`N+3H = NH_3`
So here we need 3H atoms and 1N atom to produce 1`NH_3` molecule.
If n denotes atoms we can say the direct relationship of H and N as;
`1n_N = 3n_H`
Using the above equation to make 51 H we need to to multiply the equation by 17.
`17(1n_N) = 17(3n_H)`
`17n_N = 51n_H`
So we need 17 Nitrogen atoms.
