8.16) A solution containing 94.4 mL of carbon tetrachloride, CCl4, dissolved in 250.0 mL of nitrobenzene, CoH5NO2, was placed in the freezer, which dropped the temperature to 0°C. Did the solution freeze at that temperature? If so, at what temperature? The density of CCIA is 1.59g/cm3. The density of CoH5NO2 is 1.2 g/cm3. Yes, It would freeze at 0 °C. No, it would freeze at 26.74°C. O No, it would freeze at 5.7°C. O No, it would freeze at -16.61°C. O No, it would freeze at -21.07°C.

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.

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
