If you dissolve 40 g of KCl in 100 g of H2O at 60°C would the solution be a. saturated
b. unsaturated
c. supersaturated
d. not enough information to tell

let that person have a turn to speak : )

im pretty sure its b

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.
