Answer:
NO would form 65.7 g.
H₂O would form 59.13 g.
Explanation:
Given data:
Moles of NH₃ = 2.19
Moles of O₂ = 4.93
Mass of NO produced = ?
Mass of produced H₂O = ?
Solution:
First of all we will write the balance chemical equation,
4NH₃ + 5O₂ → 4NO + 6H₂O
Now we will compare the moles of NO and H₂O with ammonia from balanced chemical equation:
NH₃ : NO NH₃ : H₂O
4 : 4 4 : 6
2.19 : 2.19 2.19 : 6/4 × 2.19 = 3.285 mol
Now we will compare the moles of NO and H₂O with oxygen from balanced chemical equation:
O₂ : NO O₂ : H₂O
5 : 4 5 : 6
4.93 : 4/5×4.93 = 3.944 mol 4.93 : 6/5 × 4.93 = 5.916 mol
we can see that moles of water and nitrogen monoxide produced from the ammonia are less, so ammonia will be limiting reactant and will limit the product yield.
Mass of water = number of moles × molar mass
Mass of water = 3.285 mol × 18 g/mol
Mass of water = 59.13 g
Mass of nitrogen monoxide = number of moles × molar mass
Mass of nitrogen monoxide = 2.19 mol × 30 g/mol
Mass of nitrogen monoxide = 65.7 g
382.75 is the temperature of the 0.750 mol of an ideal gas occupy a volume of 35.9 L at 114 kPa.
Explanation:
Given:
number of moles (n) = 0.750
volume of the gas = 35.9 litres
pressure on the ideal gas = 114 kPa or 1.125 atm
R (gas constant) = 0.0821J/Kmole
Absolute temperature of gas in celcius =?
the equation for the ideal gas is
PV = nRT
putting the values in the above equation:
T = ![\frac{PV}{RT}](https://tex.z-dn.net/?f=%5Cfrac%7BPV%7D%7BRT%7D)
= ![\frac{1.125 X 35.9}{0.75 X 0.0821}](https://tex.z-dn.net/?f=%5Cfrac%7B1.125%20X%2035.9%7D%7B0.75%20X%200.0821%7D)
= 655.907
655.9 kelvin is the temperature of the ideal gas.
To convert this unit of kelvin into degree celcius:
K-273.15 = C
655.9 - 273.15
= 382.75 degrees
382.75 degrees celcius is the temperature of the ideal gas.
