Answer:
The answer to your question is 1.40 moles of N₂O
Explanation:
Balanced equation
NH₄NO₃ ⇒ N₂O + 2 H₂O
2 -------- N ---------- 2
4 ------- H ---------- 4
3 ------- O ---------- 3
Process
1.- From the balanced equation, we know that 1 mol of NH₄NO₃ produces 1 mol of N₂O so, we use proportions to find the number of moles produced when 1.40 moles of NH₄NO₃ react.
1 mol of NH₄NO₃ ------------- 1 mol of N₂O
1.40 moles -------------- x
x = (1.40 x 1) / 1
x = 1.40 moles of N₂O are produced
Answer:
Here you can use the Clausis Clayperon equation: ln P1/P2=-Ea/R-(1/T1 - 1/T2)
where P1 is the pressure at standard condition: 760 mm Hg
P2 is the variable we need to solve
Ea is the activation energy, which in this case is delta H vaporisation: 56.9 kJ/mol
R is the gas constant 8.314 J/mol or 8.314 J/mol /1000 to convert to kJ
T1 is the normal boiling point 356.7 C, but converted to Kelvin: 629.85K
T2 is room temperature 25 C, but converted to Kelvin: 298.15 K
Once you plug everything in, you should get 4.29*10^-3 mmHg
Explanation:
The major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.
<h3>What are carbohydrates?</h3>
Carbohydrates are biological macromolecules that function as macronutrients by providing energy, which are composed of simple carbon-based molecules linked by glycosidic bonds.
In conclusion, the major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.

Answer:
0.5455
Explanation:
The moles of benzene in the process stream in 1 sec = 450 moles
The moles of toluene in the process stream in 1 sec = 375 moles
So, according to definition of mole fraction:
Applying values as:
<u>Mole fraction of benzene in the process stream = 0.5455</u>
