It is solid because of the pressure. Hope this helps :))
I'm not sure what the question is, this is a lab proecdure
Answer: The moles of carbon needed will be, 13.8 moles
Explanation: Moles of = 5.52 mole
Now we have to calculate to moles of carbon.
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 2 mole of react to give 5 moles of carbon
So, 5.52 mole of react to give moles of carbon
Therefore, the moles of carbon needed will be, 13.8 moles
The ideal gas law is: PV=nRT
Pressure
Volume
n= moles
R= gas constant
Temperature in Kelvin
(Degrees in celsius +273)
n= PV/RT
(1.00atm)(5.00L)/(.08026)(295K)= .207mol of gas
