The balanced equation
for the reaction is:
6 HNCO(l) →
C3N3(NH2)3(l) + 3 CO2(g)
Convert amount of urea
from kg to moles
Molar Mass of urea = 60.06
g/mol so, 113 kg urea contains
113 kg / 60.06 = 1.88
mol urea
From balanced equation 6
moles of urea yields only 1 melamine, so divide the moles of urea by 6.
1.88 / 6 = 0.313 kmol
melamine
Now multiply 0.313 with
molar mass of melamine that is 126 g/mol
126 x 0.313 = 39.438 kg
Yield of overall
reaction is 73% so multiply 39.438 with 0.73
<span>39.438 x 0.73 = 28.799
kg is the answer</span>
<span>The ammonia molecules have weaker inter molecular bonds then the hydrogen and nitrogen, this means that the ammonia condensed at a lower temperature so will be a liquid that will be separated from the reaction, while the nitrogen and hydrogen remain as gases so are easy are recycle back into the reacting chamber.</span>
Answer:
Intensive
Explanation:
The electrical conductivity of a wire depends on its composition, not the length of the wire.
Hope this helps! If correct pls mark brainliest :)
Pneumonia is an infection of the lungs caused by fungi, bacteria, ... These conditions include asthma, cystic fibrosis, diabetes, and heart failure.
Answer:
It has 2 eyes
Explanation:
Quantitive observation means that it is facts based of numbers, therefore you can count how many eyes it has, but not that it has red eyes
