Answer:
1.59 atm
Explanation:
The reaction is:
![N_{2}O_{3}(g) - - -> NO_{2}(g)+NO(g)](https://tex.z-dn.net/?f=N_%7B2%7DO_%7B3%7D%28g%29%20-%20-%20-%3E%20NO_%7B2%7D%28g%29%2BNO%28g%29)
The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.
So after the reaction the total pressure is:
![P_{total}=P_{NO_{2}}+P_{NO}](https://tex.z-dn.net/?f=P_%7Btotal%7D%3DP_%7BNO_%7B2%7D%7D%2BP_%7BNO%7D)
we don't include
because it decomposed completely.
Assuming ideal gases
PV=nRT
P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.
so moles of
is:
![n_{N_{2}O_{3}}=\frac{P_{1}V}{RT_{1}}](https://tex.z-dn.net/?f=n_%7BN_%7B2%7DO_%7B3%7D%7D%3D%5Cfrac%7BP_%7B1%7DV%7D%7BRT_%7B1%7D%7D)
from the reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of
.
![n_{NO_{2}}=\frac{P_{1}V}{RT_{1}}](https://tex.z-dn.net/?f=n_%7BNO_%7B2%7D%7D%3D%5Cfrac%7BP_%7B1%7DV%7D%7BRT_%7B1%7D%7D)
![n_{NO}=\frac{P_{1}V}{RT_{1}}](https://tex.z-dn.net/?f=n_%7BNO%7D%3D%5Cfrac%7BP_%7B1%7DV%7D%7BRT_%7B1%7D%7D)
The partial pressure of each gas is:
![P_{NO_{2}}=\frac{n_{NO_{2}*R*T_{2}}}{V}](https://tex.z-dn.net/?f=P_%7BNO_%7B2%7D%7D%3D%5Cfrac%7Bn_%7BNO_%7B2%7D%2AR%2AT_%7B2%7D%7D%7D%7BV%7D)
![P_{NO}=\frac{n_{NO}*R*T_{2}}{V}](https://tex.z-dn.net/?f=P_%7BNO%7D%3D%5Cfrac%7Bn_%7BNO%7D%2AR%2AT_%7B2%7D%7D%7BV%7D)
so total pressure is:
![P_{total}=(n_{NO_{2}}+n_{NO})*\frac{R*T_{2}}{V}](https://tex.z-dn.net/?f=P_%7Btotal%7D%3D%28n_%7BNO_%7B2%7D%7D%2Bn_%7BNO%7D%29%2A%5Cfrac%7BR%2AT_%7B2%7D%7D%7BV%7D)
replacing the moles we get:
![P_{total}=(2*\frac{P_{1}V}{RT_{1}})*\frac{R*T_{2}}{V}](https://tex.z-dn.net/?f=P_%7Btotal%7D%3D%282%2A%5Cfrac%7BP_%7B1%7DV%7D%7BRT_%7B1%7D%7D%29%2A%5Cfrac%7BR%2AT_%7B2%7D%7D%7BV%7D)
We know that T2=3*T1
replacing this value in the equation we get:
![P_{total}=2*\frac{P_{1}V}{RT_{1}}*\frac{R*3T_{1}}{V}](https://tex.z-dn.net/?f=P_%7Btotal%7D%3D2%2A%5Cfrac%7BP_%7B1%7DV%7D%7BRT_%7B1%7D%7D%2A%5Cfrac%7BR%2A3T_%7B1%7D%7D%7BV%7D)
![P_{total}=6*P_{1} = 6*0.265 atm = 1.59 atm](https://tex.z-dn.net/?f=P_%7Btotal%7D%3D6%2AP_%7B1%7D%20%3D%206%2A0.265%20atm%20%3D%201.59%20atm)
Answer:
decane
Explanation:
due to more covalant bonds
Answer:
A tiny sense positively charge core called a nucleus in which nearly all the mass is concentratedm
Answer: 10.63
Explanation: You divide the mass by volume.
You need 4 H2 molecules and 2 O2 molecules.
This is because water is H2O which is 2 Hydrogen and 1 Oxygen so if you want to make 4 water molecules, you’ll need 8 hydrogen and 4 oxygen.
Given H2 you need 4 because 4•2 is 8 and for O2 you need 2 because 2•2 is 4.
I hope this makes sense.
