<span>rms = (3RT/M)^1/2
Therefore, the rms of CO is:
rms(CO) = [(3)(8.3145 J/mol*K)(320 K)/(0.028 kg/mol)]^1/2
rms = [2.65x10^5 m^2/s^2]^1/2
rms = 533.9181 m/s</span>
Answer:
I think first one..........
D. Pressure vs. temperature
<u>Explanation:</u>
In physical chemistry, this diagram or graph is utilized to predict the conditions like volume, pressure and temperature at which thermodynamic- ally different phases like solid, gases and liquid occur and both states exist at equilibrium.
The simple phase diagrams are the pressure–temperature diagrams of a simple substance like water. In that diagram, x and y axes were correspond to the temperature and pressure. It shows, in the space of pressure and temperature, the equilibrium lines occur between all the 3 phases of water.
Benzoxazole is an aromatic organic compound with a molecular formula C7H5NO, a benzene-fused oxazole ring structure, and an odor similar to pyridine.[1][2] Alhtough benzoxazole itself is of little practical value, many derivatives of benzoxazoles are commercially important.
Being a heterocyclic compound, benzoxazole finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.
