2. Batman's car originally moving at a Constant velocity experiences an
acceleration of 7.5 m/s for 12 s. If
the car is now traveling at a speed of
133 m/s, what was the initial speed of
the car?

they are all solids.

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.
