Answer:
the answer would be Halogens
Answer:
to increase their number of species on the Earth and want to go long and long
We are given the complete reaction:
<span>3 H2(g) + N2(g) → 2 NH3(g)</span>
First let us convert mass to moles.
moles H2 = 5.22 kg / (2 kg/kmol) = 2.61 kmol H2
moles N2 = 31.5 kg / (28 kg/kmol) = 1.125 kmol N2
Then we find for the limiting reactant. The limiting
reactant is the one who has lower (moles/coefficient) ratio.
H2 = 2.61 / 3 = 0.87
N2 = 1.125 / 1 = 1.125
Hence the H2 is the limiting reactant so we should base
the calculation of NH3 from it. We see that 2 moles of NH3 is produced for
every 3 moles of H2, therefore:
moles NH3 = 2.61 kmol H2 * (2 kmol NH3 / 3 kmol H2) = 1.74
kmol
The molar mass of NH3 is 17 kg/kmol, therefore the mass
NH3 is:
mass NH3 = 1.74 kmol * 17 kg/kmol
<span>mass NH3 = 29.58 kg</span>
