N2 + 3h2 → 2nh3 how many moles of hydrogen, h2, are needed to react with 2.0 moles of nitrogen, n2? round final answers to the tenth position, one place after the decimal. only report the numerical answer. my answer was 10.8

 The number of  moles  of H₂ that are needed  to react with 2.0  moles of N₂  is    6.0 moles

 calculation

N₂  +3H₂→   2NH₃

The moles of  H₂  is  calculated  using the mole ratio

That is from equation above  N₂:H₂  is 1 :3

therefore the moles of  H₂ = 2.0  moles  x (3/1) = 6.0 moles

h let me think

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
