N2+3H2->2NH3
When 3 moles of H2 react, they produce 2 moles of NH3
3 moles of H2 have a mass of 2.02 g
2 moles of NH2 have a mass of 17.0 g
So when 2.02 g H2 react, they produce 17.0 g NH3
If 26.3g H2 react with a yield of 100%, we expect…
2.02g H2_____17.0gNH3
26.3g H2_____x=221gNH3
So now let’s calculate the percentage:
221gNH3_________100%
79.0gNH3_________x=79.0*100/221=35.7%

Answer
Correct Answers are Mid ocean ridges are sites of seafloor spreading
and Younger ocean floor is created
Explanation
Harry H. Hess was a geophysicist. In 1960, he proposed a theory which is later became known as 'Sea Floor Spreading'. Hess discovered that the oceans were shallower in the middle. According to Hess, From Earth’s mantle molten material is continuously flowing along the crests of the mid-ocean ridges.
As soon as temperature of magma decreases, it is pushed away from the flanks of the ridges. Due to this process a younger ocean floor is created.
Hess also proposed that due to light weight of continental crust, it didn't sink back into the deep earth at trenches as did the oceanic crust.
