15. Use the chemical equation below to determine how many moles of ammonia (NH) will be produced from 4 moles of nitrogen gas (N). Assume that there is enough H, for all of the N, to be converted to NH.
N2 + 3H2 + 2NH
8 moles
2 moles
3 moles
4 moles

I'm not really sure but I think it is

four

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
