Drag each label to the correct location on the image. Each label can be used more than once. The position-time graph describes the motion of a moving object. Describe the motion represented by each segment of the graph.

A- not moving
B- constant velocity
C- positive acceleration
D- negative acceleration

a) the particles of the chair are strongly held together.

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.
