1) Excess reagent
1 mol N2 / 3 mol H2
6.0 mol N2 *3 mol H2 / 1 mol N2 = 18 mol H2
18mol H2 > 12 mol H2 => H2 is limiting (you need 18 mol H2 to use all the 6 mol N2), then N2 is in excees.
12.0 mol H2 * 1mol N2/ 3 mol H2 = 4 mol N2 is the quantity that will react, then the excess is 6 mol N2 - 4 mol N2 = 2 mol N2
2) NH3 produced
12 mol H2 * [2 mol NH3 / 3 mol H2] = 8 mol NH3
Aslso, 4 mol N2 *[2molNH3 / 1 molN2] = 8 mol NH3, the same result.
3) Yield
80% * 8 mol NH3 = 6.4 mol NH3

Answer:
Similarities
1. Fresh water and marine water both are essential parts of the water cycle.
2. They contain the same chemical and the amount of minerals in both the ecosystems is same.
3. Both addresses to the aquatic development.
Dissimilarities
1. Marine water carries much higher amounts of suspended chemicals as related to fresh water.
2. This larger collection of the chemical also increases the quantity of salt in marine water than that of fresh water.
3. Plant and animals existing in these water bodies also differ.
