Mario takes a cup of water and adds one drop of blue food coloring. He stirs the solution. His lab partner, Liza, records their observations and then adds another cup of water to the solution. What will happen? A) The solution will get warmer. B) The volume of the container will go down. C) The mass of the container will not change. D) The color of the solution will get lighter.

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.
