The vapor pressure of liquid iodomethane, CH3I, is 40.0 mm Hg at 249 K.A sample of CH3I is placed in a closed, evacuated contain
lora16 [44]

Explanation:

It is given that vapor pressure of liquid iodomethane is 40.0 mm Hg. So, if we calculate the vapor pressure according to the given values and if its value will be greater than the the given vapor pressure of iodomethane then it means that some of the vapors has converted into liquid state.

As the given values are as follows.

      P_{1} = 72.0 mm Hg,       T_{1} = 404 K

      P_{2} = ? ,               T_{2} = 249 K

As volume is constant so, according to Gay-Lussac's law pressure is directly proportional to temperature.

                      P \propto T         (at constant volume)

or,                    \frac{P}{T} = k

Therefore, the formula to calculate the value of P_{2} is as follows.

              \frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}

            \frac{72.0 mm Hg}{404 K} = \frac{P_{2}}{249 K}

                 P_{2} = 44.37 mm Hg

As calculated vapor pressure is more than the given vapor pressure. Hence, the liquid will convert into gas.

As a result, no condensation will occur and only vapors of iodomethane will be present.

Which electrophiles can react with an enol?
dlinn [17]

THE MOLECULE HAS A C=C AND AN -OH GROUP, SO IT IS CALLED AN ENE/OL, I.E., AN ENOL. ENOLS CAN BE FORMED ONLY FROM CARBONYL COMPOUNDS WHICH HAVE ALPHA HYDROGENS. THEY CAN BE FORMED BY ACID OR BASE CATALYSIS, AND ONCE FORMED ARE HIGHLY REACTIVE TOWARD ELECTROPHILES, LIKE BROMINE.

If you refuse a legal chemical test issued by a law enforcement officer, the Division of Motor Vehicles is required to:
Andru [333]

Answer: Revoke the driver's license for at least 12 months
