If I have a 70 liter container that holds 45 moles of gas at a temperature
of 3000C, what is the pressure inside the container? Use .0821 L-atm/k-
mol

the answer would be 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.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
