Two hundred grams of benzene were vaporized at it's boiling Points of 80.2°C at 76 cm Pressure Talking the heat of vaporization of benzene as 394.592 J/g calculate . (a) W (b) q (c) dH ​

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

bcde is the incorrect answer it is a

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
