Answer: 0.0014 atm
Explanation:
Given that,
Original pressure of air (P1) = 1.08 atm
Original volume of air (T1) = 145mL
[Convert 145mL to liters
If 1000mL = 1l
145mL = 145/1000 = 0.145L]
New volume of air (V2) = 111L
New pressure of air (P2) = ?
Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law
P1V1 = P2V2
1.08 atm x 0.145L = P2 x 111L
0.1566 atm•L = 111L•P2
Divide both sides by 111L
0.1566 atm•L/111L = 111L•P2/111L
0.0014 atm = P2
Thus, the new pressure of air when the volume is decreased to 111 L is 0.0014 atm
Answer:
Initially
of nitrogen dioxide were in the container .
Explanation:
Volume of the container at low pressure and at room temperature =![V_1=3.4 L](https://tex.z-dn.net/?f=V_1%3D3.4%20L)
Number of moles in the container = ![n_1](https://tex.z-dn.net/?f=n_1)
After more addition of nitrogen gas at the same pressure and temperature.
Volume of the container after addition = ![V_2=5.11 L](https://tex.z-dn.net/?f=V_2%3D5.11%20L)
Number of moles in the container after addition=![n_2=2.28\times 10^{-2} mol](https://tex.z-dn.net/?f=n_2%3D2.28%5Ctimes%2010%5E%7B-2%7D%20mol)
Applying Avogadro's law:
(at constant pressure and temperature)
![\frac{V_1}{n_1}=\frac{V_2}{n_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7Bn_1%7D%3D%5Cfrac%7BV_2%7D%7Bn_2%7D)
![n_1=\frac{V_1\times n_2}{V_2}=\frac{3.4 L\times 2.28\times 10^{-2} mol}{5.11 L}](https://tex.z-dn.net/?f=n_1%3D%5Cfrac%7BV_1%5Ctimes%20n_2%7D%7BV_2%7D%3D%5Cfrac%7B3.4%20L%5Ctimes%202.28%5Ctimes%2010%5E%7B-2%7D%20mol%7D%7B5.11%20L%7D)
![n_1=1.51\times 10^{-2} mol](https://tex.z-dn.net/?f=n_1%3D1.51%5Ctimes%2010%5E%7B-2%7D%20mol)
Initially
of nitrogen dioxide were in the container .
I believe the answer is compound B may have a lower molecular weight compared to compound A.
At the same temperature, lighter particles of a compound have a higher average speeds than do heavier particles of another compound. Thus, particles of compound B are lighter than those of compound A and thus they have a higher average speed, hence evaporating faster compared to compound A.
Answer:
Compounds formed from non-metals consist of molecules.
Explanation:
The atoms in a molecule are joined together by covalent bonds. These bonds form when atoms share pairs of electrons.
I hope I helped, please correct me if I'm wrong!
