You need to moles of potassium chloride in order to perform a chemical reaction explain how you would figure out how much you needed in the lab and how you were measured it out (would it be by mass, volume of molecules?)

hurricanes form in warm water

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.

explanation:

0.07 g/cm³

1.37 g/cm³
