Which of these is an unsaturated solution? Choose ALL that apply. O 50 g of KCI in 50 g of water at 90°C
60 g of NH4Cl in 100 g of water at 80°C
O 70 g of NH3 in 100 g of water at 20°C
50 g of NH4Cl in 100 g of water at 60°C
80 g of KNO3 in 100 g of water at 60°C
O 60 g of Kl in 50 g of water at 10°C

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

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.
