What would happen to the retention time of a compound if the following changes were made? Decrease the flow rate of the carrier gas Increase the temperature of the column Increase the length of the column How do the temperature and flow rate of the carrier gas affect the separation of two compounds that have been shown to separate by GC? 5.

4. The compounds in a mixture separated by GC can be identified by their retention times. If you Suructor nad not told you which peak in the GC chromatogram corresponded to which alker you didn't know the boiling points of the alkenes, how could you determine the identity or each peak by its retention time? Identities of the components in a mixture separated by GC can also be determined by the technique called "spiking". Suppose you had run a chromatogram...

Suppose a firm's tax rate is 35%. 1. What effect would a $9.74 million operating expense have on this year's earnings? What effect would it have on next year's earnings? (Select all the choices that apply.) A. A $9.74 million operating expense would be immediately expensed, increasing operating expenses by $9.74 million. This would lead to a reduction in taxes of 35 % times $ 9.74 million equals $ 3.41 million 35%×$9.74 million=$3.41 million. B. A $9.74 million operating expense...
