Max ! a student places a strip of magnesium on an electronic balance and it show the mass of the magnesium to be 101.32 grams. which of these numbers is an estimate?

c, liquids evaporate, creating a gas

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.
