Question

help please.....anyone?

Answer 1

H2 + N2 -----> NH3
to find the moles from volume, use this formula,
n=V/Vm
n=moles
V=volume
Vm= molar volume = 22.4 dm3
and then balance it

Answer 2

i'd balance the reaction first, it's just a good habit to get into. then start converting units and plugging in numbers

Answer 3

N2 + 3(H2) ---------> 2(NH3)

Answer 4

N2 + 1+1/2 H2 -> NH3
