What is the volume of a 12.2 g piece of metal with a density of 9.43 g/cm??

1.29

Explanation:

You have to find the equation which is d=m/v. d is 9.43=12.2/v. You have to solve for v which you get 1.29

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.
