Answer: 322.56 Kelvin

Explanation:

Use the Ideal Gas Law

$PV=nRT$

R is the gas constant

T is the temperature in Kelvins

P is the pressure in atmospheres

V is the volume in liters

n is the number of moles of gas

First, the mm of mercury need to be converted to atmospheres using the conversion factor 1atm = 760 torr.

$751.2mmHg (torr) =0.988atm$

Now plug everything in

$(0.988)(26)=(0.97)(0.0821)T\\T=322.56K$

Answer:

1-Pentene

Explanation:

If we look at all the options listed, we will notice that the rate of reaction of bromine with each one differs significantly.

For 1-pentene, addition of bromine across the double bond is a relatively fast process. It is usually used as a test for unsaturation. Bromine water is easily decolorized by alkenes.

Cyclohexane, heptane are alkanes. They can only react with chlorine in the presence of sunlight. This is a substitution reaction. It does not occur easily. A certain quantum of light is required for the reaction to occur.

For benzene, bromine can only react with it by electrophilic substitution in which the benzene ring is retained. A Lewis acid is often required for the reaction to occur and it doesn't occur easily.
