Answer:
The value of maximum pressure the balloon could be filled = 6.40 atmosphere.
Explanation:
When helium from the cylinder is filled inside the balloon the heat & work
transfer is zero during the process. so from the first law of thermodynamics
change in internal energy is zero.
⇒ = 0
⇒ =
⇒ = ------------- (1)
Final temperature is equal to initial temperature.
Equation (1) can be written as
⇒ = -------------(2)
Initial volume = 44 L
Final volume = 296 L
Initial pressure = 43.1 atmosphere
Final pressure = we have to calculate
Put all the values in Equation (2) we get,
⇒ × 296 = 43.1 × 44
⇒ = 6.40 atmosphere
This is the value of maximum pressure the balloon could be filled.
Answer:
The answer is option 2 : NO3
Answer:
3.55 x 10^23 molecules F2
Explanation:
molecules = moles x avogadro number
1 mole of gas occupies 22.4 L
moles of F2 = 13.2/22.4= 0.589 moles
moles F2 = 0.589 x 6.022 x 10^23 = 3.55 x 10^23 molecules F2
C) The bonding between carbon atoms allows for branches in carbon chains.
