Answer:
if a 40.0-gram sample of the gas occupies 11.2 liters of space at STP? A balloon is filled with 5 moles of helium gas.
Explanation:
I: Current
V: Voltage
R: resistance
you’re welcome ;)
Answer:
The minimum volume of the container is 0.0649 cubic meters, which is the same as 64.9 liters.
Explanation:
Assume that ethane behaves as an ideal gas under these conditions.
By the ideal gas law,
,
.
where
- is the pressure of the gas,
- is the volume of the gas,
- is the number of moles of particles in this gas,
- is the ideal gas constant, and
- is the absolute temperature of the gas (in degrees Kelvins.)
The numerical value of will be if , , and are in SI units. Convert these values to SI units:
- ;
- shall be in cubic meters, ;
- .
Apply the ideal gas law:
.
Answer:
5.995 psi
Explanation:
30 psi = 2.04 atm
75 mL = 0.075 L
15 mL = 0.015 L
0.075 L/ 2.04 atm = 0.015 L/x
0.075x = 0.0306
x = 0.408
0.408 atm = 5.995 psi
Answer:
answer is b
Explanation:
I think it is b. I don't know what land lenses are but focusing light on the can would heat it up more.
