Most divergent plate boundaries are underwater (Iceland is an exception) and form submarine mountain ranges called oceanic spreading ridges. While the process is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
Answer:
506kg
Explanation:
From the reaction equation, we can see that 3 moles of hydrogen yielded 2 moles of ammonia.
Now we need to calculate the number of moles of hydrogen reacted. This mathematically equals the mass of hydrogen reacted divided by the molecular mass of the hydrogen molecule.
The mass of hydrogen reacted is 89.5kg. This equals 89.5 × 1000g which equals 89500g. The molecular mass of hydrogen is 2g/mole ( 1 atom of hydrogen has an atomic mass unit of 1 and 1 molecule of hydrogen has 2 atoms).
Now we mathematically calculate the number of moles of hydrogen reacted to be 89500/2 which equals 44,750 moles.
If 3 moles of hydrogen yielded 2 moles of ammonia gas, then 44, 750 moles will yield 44,750 × (2/3) which equals 29,833 moles of Ammonia gas.
Now, let's calculate the mass of Ammonia gas yielded. This mathematically equals the number of moles of ammonia gas yielded multiplied by the molar mass of ammonia gas. The molar mass of ammonia gas is (14 + 3(1)) which equals 17g/mole.
Hence, the mass yielded equals 29,833 × 17 = 506167g
This equals 506,167 ÷ 1000 = 506.167kg.

Sorry I didn’t get the answer
Answer:
a physical change does not change the composition (what it's made of) as a chemical change would.
