Question: A gas mixture is made by combining 8.9 g each of Ar, Ne, and an unknown diatomic gas. At STP, the mixture occupies a volume of 21.10 L. What is molar mass of the unknown gas?
The concentrations of each were then determined as follows: [Fe^3+]= 6.8 x 10 ^-4 M, [SCN ^-]= 3.3 x 10 ^-4 M, [FeSCN ^2+]= 3.0 X 10 ^-5 M. Determine the equilibrium constant for this reaction.
In vibrational motion of HI (g), the iodine atom essentially remains stationary because of its relatively large mass. Assume that the hydrogen atom undergoes harmonic motion and that the force constant is 313.8 N/m
