Answer:
256 K
Explanation:
Given data
- Ideal gas constant (R): 0.0821 atm.L/mol.K
We can determine the temperature of the gas using the ideal gas equation.
P × V = n × R × T
T = P × V / n × R
T = 4.20 atm × 20.0 L / 4.00 mol × 0.0821 atm.L/mol.K
T = 256 K
Answer:
A. Biomass
Explanation:
Biomass must be burned to be useful as a fuel.
The combustion of biomass produces carbon dioxide, which is a greenhouse gas.
B, C, and C are wrong. Once these energy sources are built, they produce no greenhouse gases.
Without a list to choose from I would say Hydrocarbons.
Answer:
coloumbs
Explanation:
the value of the charge on a proton is Coloumbs
Answer: The pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.
Explanation:
Given:
,
, ![T_{1} = 308 K](https://tex.z-dn.net/?f=T_%7B1%7D%20%3D%20308%20K)
,
, ![T_{1} = 373 K](https://tex.z-dn.net/?f=T_%7B1%7D%20%3D%20373%20K)
Formula used to calculate the final pressure is as follows.
![\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7DV_%7B1%7D%7D%7BT_%7B1%7D%7D%20%3D%20%5Cfrac%7BP_%7B2%7DV_%7B2%7D%7D%7BT_%7B2%7D%7D)
Substitute the values into above formula as follows.
![\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{1.34 atm \times 2.50 L}{308 K} = \frac{P_{2} \times 1.90 L}{373 K}\\P_{2} = \frac{1.34 atm \times 2.50 L \times 373}{308 K \times 1.90 L}\\= 2.14 atm](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7DV_%7B1%7D%7D%7BT_%7B1%7D%7D%20%3D%20%5Cfrac%7BP_%7B2%7DV_%7B2%7D%7D%7BT_%7B2%7D%7D%5C%5C%5Cfrac%7B1.34%20atm%20%5Ctimes%202.50%20L%7D%7B308%20K%7D%20%3D%20%5Cfrac%7BP_%7B2%7D%20%5Ctimes%201.90%20L%7D%7B373%20K%7D%5C%5CP_%7B2%7D%20%3D%20%5Cfrac%7B1.34%20atm%20%5Ctimes%202.50%20L%20%5Ctimes%20373%7D%7B308%20K%20%5Ctimes%201.90%20L%7D%5C%5C%3D%202.14%20atm)
Thus, we can conclude that the pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.
