9. Consider section 10.4 (The Ideal Gas-Equation) in your textbook and our Aug 30 lecture. Imagine that you have 0.80 mol of kryptonite gas enclosed in a 500-ml platinum vessel equipped with a
manometer. The manometer reads 550 psi, What is the temperature (Kelvin) of the kryptonite gas in
the vessel? (NB: the gas constant value
for this situation is expressed as 0.08206 L-atm/mol-K).

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.
