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>
Answer: clay, silt, sand, pebble, cobble, and boulder.
HCl is lewis acid
And NH4+is conjugate acid
Answer:
(slow)xy2+z→xy2z (fast) c step1:step2:xy2+z2→xy2z2
Explanation:
Step1: xy2+z2→xy2z2 (slow)
Step2: xy2z2→xy2z+z (fast)
2XY 2 + Z 2 → 2XY 2 Z
Rate= k[xy2][z2]
When the two elementary steps are summed up, the result is equivalent to the stoichiometric equation. Hence, this mechanism is acceptable. The order of both elementary steps is 2, which is ‘≤3’; this also makes this mechanism acceptable. Furthermore, the rate equation aligns with the experimentally determined rate equation, and this also makes this mechanism acceptable. Therefore, since all the three rules have been observed, this mechanism is possible.
Any fire extinguisher should put out a fire, that is unless the extinguisher is old and faulty.
