What is the pressure of 4 moles of helium in a 50 L tank at 308 K? Use PV = nRT.
O A. 0.51 atm
O B. 24.64 atm
O C. 2.02 atm
OD. 0.13 atm

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
