17. Using the ideal gas law, PV = nRT, in which R is 8.31 (LkPa/mol·K), what would the temperature be if 0.75 moles of helium gas in a 2.0L container have a pressure of 202.65 kPa?
O 540 K
O 9.1K
O 630 K
O 65 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.
