Answer:
8.33 moles CO2 X. 25mol O2. 16mol CO2. = 13.0 moles
Answer:
The answer would either be Carbon or Silicon.
Explanation:
Use the ideal gas law:
PV = nRT
so, T = PV / nR
n=0.5
V= 120 dm^3 = 120 L (1 dm^3 = 1 L)
R = 1/12
P = 15,000 Pa = 0.147 atm (1 pa = 9.86 10^{-6} )
Put the values:
T = PV / nR
T = (0.147) (120) / (0.5) (1/12)
T= 426 K
The 2 represents that it is a double carbon bond
it looks like..
C-C = C-C
